SOMATOM Perspective
“Open new opportunities” VS. “Close doors to growth”
Second best is not an option.
Healthcare service providers are increasingly facing rising costs and shrinking budgets. At the
same time, demand for flawless healthcare has intensified. These two factors make the efficient
use of medical devices crucial to success in clinical practice. Siemens has the ideal answer
to these challenges: SOMATOM Perspective, a CT scanner applicable for all clinical fields that
delivers economical benefits without compromising on patient care.
Equipped with innovative Siemens technology, such as the raw-data based iterative
reconstruction SAFIRE*, SOMATOM Perspective enables better diagnosis while reducing dose –
without sacrificing image quality.
SOMATOM Perspective also improves cost efficiency. The unique eCockpit extends the scanner’s
lifespan by preventing unnecessary wear and tear, and reduces overheads by minimizing energy
consumption. Plus, SOMATOM Perspective is available in four upgradable configurations,
giving healthcare facilities the possibility to tailor the investment to their needs and to grow
In short, SOMATOM Perspective helps to enhance patient care and improve financial
performance – opening new opportunities for hospitals and clinics.
* In clinical practice, the use of
SAFIRE may reduce CT patient dose
depending on the clinical task,
patient size, anatomical location,
and clinical practice. A consultation
with a radiologist and a physicist
should be made to determine the
appropriate dose to obtain
diagnostic image quality for the
particular clinical task.
Widen your clinical portfolio
SOMATOM Perspective covers a wide range of clinical fields
and makes even challenging exams routine.
Image quality
High-quality, detailed images are essential
for accurate diagnoses, particularly when it
comes to small structures – for example,
when evaluating fractures. SOMATOM
Perspective is equipped with Interleaved
Volume Reconstruction (IVR), a technology
that enhances spatial resolution along the
patient’s longitudinal axis by increasing the
number of data points. For this, IVR
generates up to 128 slices during the image
reconstruction. This makes it possible to
visualize very small structures, such as
fine fractures.
The right dose
Multiple follow-up scans and intraoperative
imaging are becoming standard in clinical
practice – so minimizing patients’ and
medical professionals’ radiation exposure is
more important than ever. In addition, lowdose exams make facilities more attractive
for referring physicians. SOMATOM
Perspective offers a number of impressive
dose-reduction features, one particularly
innovative feature is the Sinogram Affirmed
Iterative Reconstruction (SAFIRE). It makes it
possible to reduce dose by up to 60%*.
iMAR – iterative Metal Artifacts Reduction
Improves diagnostic confidence by reducing
metal artifacts – even in challenging cases
like dental fillings, spine implants, and
iMAR is based on the Adaptive Sinogram
Mixing. It combines a strong metal artifact
removal method in areas with severe
artifacts and a soft correction in areas with
less severe artifacts.
The result is an outstanding image quality
with metal artifacts removed while valuable
information remains.
SOMATOM Perspective is
based on a brand-new system
platform that supports a wide
range of clinical fields to open
new opportunities for hospitals
and clinics.
CT-guided interventions
There is a growing need for CT image guidance in minimally invasive interventions.
SOMATOM Perspective is perfectly suited for
guided biopsies, drainages and spinal
injections. It enables 2D CT guidance and
CT fluoroscopy to scan continuously, and
makes it possible to view images in near
real-time to hit the target on the first try.
The wireless tableside i-Control provides full
control of table movement and software
functions. This level of usability is unprecedented on the market and gives Siemens a
definitive edge in CT-guided intervention.
Single Source Dual Energy
Metal artifacts can present a major
challenge when imaging hip implants or
complicated fractures for post-surgery
diagnosis. This is where Single Source Dual
Energy technology comes in. It adds
valuable quantitative information to the
morphology of conventional CT scans to
significantly reduce metal artifacts. Single
Source Dual Energy technology can also
be used in other clinical fields, such as
evaluating kidney stones and verifying gout
diagnoses. And best of all, the examination
is as easy to set up as a regular spiral scan.
Full cardio functionality
Multiple features are available for
streamlining and enhancing complex
cardiac imaging procedures. iTRIM (Iterative
Temporal Resolution Improvement Method),
for example, improves the temporal
resolution to as low as 195 ms to reduce
motion artifacts in cardiac imaging. The
FAST Cardio Wizard provides step-by-step
guidance for higher reliability and
reproducibility. Moreover, ECG Check and
Cardio BestPhase automatically identify the
most suitable arterial phases.
* In clinical practice, the use of
SAFIRE may reduce CT patient dose
depending on the clinical task,
patient size, anatomical location,
and clinical practice. A consultation
with a radiologist and a physicist
should be made to determine the
appropriate dose to obtain
diagnostic image quality for the
particular clinical task.
The following test method was
used to determine a 54 to 60%
dose reduction when using the
SAFIRE reconstruction software.
Noise, CT numbers, homogeneity,
low-contrast resolution and highcontrast resolution were assessed
in a Gammex 438 phantom.
Low-dose data reconstructed with
SAFIRE showed the same image
quality compared to full-dose data
based on this test. Data on file.
Manage your financial performance
SOMATOM Perspective is designed to reduce costs across the
entire lifecycle, allowing more medical institutions to enhance
patient care.
The most economical CT of its class
When choosing a CT scanner, there is
much more to consider than just the initial
investment. Running costs, added up over
the hardware’s lifetime, must also be
factored in when calculating the return on
investment. SOMATOM Perspective was
designed for cost-effective installation and
everyday operation. With its slim gantry and
sleek design, SOMATOM Perspective takes
up just 18.5 m2 (199 ft2) of floor space.
Installation is simple, and often takes less
than two days. As it only requires
70 kVA, there is no need for power
upgrades – allowing you to use existing
CT electricity sources. The low power
requirement reduces the scanner’s heat
dissipation to just 8.5 kW. This means it
requires less cooling, reducing overall
electricity consumption by up to 50%
compared to a conventional CT scanner.
In addition to clinical requirements,
SOMATOM Perspective also
addresses financial demands of
business administrators.
Efficient operation with eCockpit
Today’s medical facilities face increasing
pressure to cut costs while maintaining or
boosting standards of care. For CT departments, this means minimizing runtime costs
while delivering better clinical diagnoses.
This is where SOMATOM Perspective’s
unique eCockpit suite comes in. eCockpit is
a bundle of new features that support
highly economic scanner usage and reduce
overhead costs. The entire working day was
taken into account, from start-up to
scanning to scan breaks. eStart gradually
warms up the tube after extended periods
of non-use (such as overnight), reducing
wear and tear associated with cold starts of
the tube. eMode automatically helps to
ensure the optimum balance between dose,
efficiency, and image quality – and further
extends the scanner’s lifespan. eSleep
minimizes electricity consumption while the
scanner is not in use, for example overnight
or during breaks, avoiding increases in
operating costs.
Future-proof investment
Healthcare facilities operate in a rapidly
changing and often unpredictable financial
environment – so flexibility is a must.
Choosing SOMATOM Perspective means
being prepared for today and tomorrow.
The scanner is available in four upgradeable
configurations: from the versatile 16-slice to
the powerful 128-slice version for more
advanced applications. It can be fully
upgraded on-site, at any time – making it a
future-proof investment that can grow with
changing needs and open new opportunities.
Ease your working day
SOMATOM Perspective offers a streamlined workflow
to ease examination procedures for both users and patients.
Expediting the daily routine
Efficient workflows are key in today’s
medical facilities. To this end, all SOMATOM
Perspective configurations feature Fully
Assisting Scanner Technologies (FAST) to
automate time-consuming processes. In the
daily routine, FAST Planning enables oneclick positioning of the scan and recon
range, ensuring a more reproduceable,
faster and more standardized workflow.
This reduces the risk of rescanning due to
incorrect positioning. In addition, this
feature can be used in critical clinical
situations where there is no time for
extensive manual CT preparations.
FAST Spine helps streamline another highly
time-intensive task: the preparation of
anatomically aligned spine reconstructions.
The software detects and labels vertebrae
within a predetermined scan area, and
calculates their position for anatomically
correct image reconstruction. This delivers
significant time savings while reducing the
risk of mislabeling associated with manual
A streamlined workflow is about
more than just throughput. It also
provides maximum efficiency of
both staff and the CT system, for
every case.
Illumination MoodlightTM
Making examinations less stressful,
particularly for children and claustrophobic
patients, helps optimize workflows and boost
throughput. SOMATOM Perspective includes
the Illumination Moodlight – an LED panel
integrated into the sleek, modern gantry. The
color can be easily adjusted to the operator’s
or the patient’s preference, providing a more
comfortable scanning environment. The
Illumination Moodlight can change color
throughout the day, or may be set to a single
tone that harmonizes with the room.
Integrated display panel
The display panel on the front of the gantry
shows current scan parameters such as kV,
mA, scan time, table position, gantry tilt,
and ECG trace – a major benefit during
cardio exams. In addition, it displays the
patient’s name for better communication.
Slim design
SOMATOM Perspective boasts a
very slim gantry: just 68 cm (26.8 inches)
deep. This streamlined design increases
patient comfort and provides easy access
during interventional procedures.
Storage box
Having accessories close at hand makes
patient positioning faster and easier. The
convenient integrated storage box holds all
basic CT positioning accessories.
Added benefits of post-processing
The post-processing software syngo.via from Siemens helps
prepare cases, enhances interdisciplinary collaboration, and
facilitates faster, more reliable diagnoses.
syngo®.via for sustainable care
As the number of chronic disease patients
rises, the demand for high-quality and
efficient care is increasing. syngo.via,
Siemensʼ state-of-the-art imaging software,
provides an excellent user experience and
boosts efficiency. syngo.via helps foster
sustainable care by equipping physicians
with workflows and applications for
evaluating images from multiple modalities
– also including Computed Tomography.
Automated Case Preparation
syngo.via assists in the analysis of individual
cases, prepares images, suggests an optimized workflow, and offers guidance when
needed. For example, when a cardiac case
is opened, Automated Case Preparation
has already pre-processed the images and
displays them in the appropriate layout
together with the right evaluation tools.
Evaluation of the coronary vessels, the
functional parameters, and the prepared
calcium score can start immediately.
Image networking
syngo.via speeds up the way users connect
and share information with clinical partners
and patients – even on the go.* syngo.via’s
client-server configuration supports task
sharing within teams, just as required in
3D labs and larger radiology departments.
Images can be shared among multiple users
at once, providing a sound basis for joint
preprocedural planning.
syngo.CT Bone Reading –
rib and spine assessment
redefined (left).
CT Oncology Engine – singleclick oncological quantification
Functions tailored to any clinical field
syngo.via includes standard functionality
for general 2D, 3D, and 4D multi-modality
reading. To complement this standard
configuration, Siemens offers additional
specialized applications – available either
single or bundled as the CT Clinical Engines.
Engines are fine-tuned for specific diagnostic
procedures, comprising the most innovative
scanner hardware and highly advanced
software applications. SOMATOM Perspective
optionally features the CT Acute Care Engine,
the Cardio-Vascular Engine, the CT Neuro
Engine, and the CT Oncology Engine.
Oncological imaging
One of the most common CT use cases
is oncological imaging. Here, SOMATOM
Perspective and syngo.via are an ideal
combination. They make it possible to
reliably find the tumor, stage it, and
conduct follow-up comparisons of all
cancerous findings at different time points.
Besides semi-automated RECIST and
volume measurements, the CT Oncology
Engine even allows quantification beyond
size. Advanced HU Statistics provides
quantification of tumor tissue, identifying
hypodense areas that could be an indicator
of tumor necrosis and potential therapy
response (right image above). In addition,
syngo.CT Bone Reading delivers revolutionary visualization of the bony structures that
need to be assessed in every routine chest
and abdominal CT scan. The ribs and spine
are displayed “rolled” onto a 2D image
plane (left image above), for simpler
reading. In short, SOMATOM Perspective
and the CT Oncology applications provide
quantitative information for making wellinformed decisions.

Best image quality at the right dose
SAFIRE* brings the full dose-saving potential
of iterative reconstruction to clinical
practice. The new, powerful SOMATOM
Perspective image reconstruction system
(IRS) can process up to 15 images per
second, making SAFIRE suitable for everyday
use. Dose can be reduced by up to 60% as
an image-improvement process is launched
right after the scan to reduce noise and
artifacts. Iterative loops are performed in
the image and the raw data space.
Without SAFIRE
Artifact cancelation
The process starts with an image
reconstruction in the raw data space by a
filtered back projection (1). The resulting
image is converted again into a sinogram
with a forward projection (2) to validate it
again with the measured data (3). During
this step, artifacts still present in the
sinogram are detected and removed.
Noise cancelation
In the image data space the image from the
filtered back projection is also validated (4)
with the measured data to lower noise. At
the end of the process, a high-quality
diagnostic image is produced, with excellent
contrast, sharpness and noise levels –
despite a potential initial dose reduction.
SAFIRE significantly improves
image quality.
* In clinical practice, the use of
SAFIRE may reduce CT patient dose
depending on the clinical task,
patient size, anatomical location,
and clinical practice. A consultation
with a radiologist and a physicist
should be made to determine the
appropriate dose to obtain
diagnostic image quality for the
particular clinical task.
The following test method was
used to determine a 54 to 60%
dose reduction when using the
SAFIRE reconstruction software.
Noise, CT numbers, homogeneity,
low-contrast resolution and high
contrast resolution were assessed
in a Gammex 438 phantom.
Low dose data reconstructed with
SAFIRE showed the same image
quality compared to full dose data
based on this test. Data on file.

The Iterative Temporal Resolution
Improvement Method (iTRIM) delivers a
superior temporal resolution compared to
conventionally reconstructed CT images,
while maintaining the same overall image
impression. It improves the temporal
resolution by 20%, and effectively reduces
motion artifacts.
140° partial dataset
180° regular dataset
Minimized motion artifacts
iTRIM uses a full 180° in combination with
a partial 140° cardiac dataset for image
reconstruction. The regular 180° dataset has
the necessary information for a completed
cardiac image but may exhibit motion
artifacts. On the other hand the 140°
dataset has a better temporal resolution and
achieves sharper delineation and edges in
areas with higher motion in the image.
Improved temporal resolution
In regions that exhibit motion, the
140° image is used as the final image –
as opposed to the full 180° image for static
regions. The iTRIM reconstruction technique
maintains the same noise level and overall
image quality, while significantly reducing
motion artifacts. This has been objectively
validated in a clinical study*. iTRIM can
dramatically improve temporal resolution –
to as low as 195 ms.
The results using iTRIM show
significantly reduced motion
artifacts compared to the
conventional reconstruction.

The eCockpit suite extends the scanner’s lifespan,
keeps operating costs in check, and seamlessly
integrates into your daily routine.
The unique eCockpit features
eStart, eMode and eSleep
The unique eCockpit suite, standard on all
SOMATOM Perspective scanners, enables
more cost-efficient operation. The entire
working day of a CT system was taken into
consideration, from start-up to scanning to
scan breaks. The features eStart, eMode and
eSleep extend the scanner’s lifespan by
preventing unnecessary wear and tear, and
reduce overhead costs by minimizing energy
consumption. And thanks to a high degree
of automation, the features can be easily
integrated into everyday workflows.
Critical temperature incr
Without eStart
The pioneering eStart feature gently
warms up the tube after extended periods
of non-use. That may be every morning
for high-throughput facilities, or prior to
each scan in smaller hospitals. This reduces
deterioration associated with cold starts,
extending the tube’s lifespan. For urgent
cases, for example in traumatology, it is of
course possible to start the scan without
eStart – saving time where it counts.
The easy-to-use eMode enables effective
and patient-friendly operation by striking
the right balance between dose, image
quality, and efficiency. Once the user has
prepared a scan protocol and entered all
required information, eMode analyzes the
parameters in real time and instantly
fine-tunes the scan. This ensures that the
system is not operated at peak or system
limit values, reducing wear and tear of
all moveable parts while maximizing
image quality.
eSleep minimizes electricity consumption
while the scanner is not in use, keeping
operating costs in check. SOMATOM
Perspective automatically enters eSleep
mode following extended periods of nonuse, such as at night or during staff lunch
breaks. What’s more, the system rapidly
returns to scan-ready mode when needed,
allowing users to resume their normal
routines in no time.
