Split-Second
Scanning
How often has your daily practice been interrupted or delayed by fragile,
sick, or traumatic patients who either cannot hold their breath or become
impatient during regular scan procedures? Finding a solution to these
hindrances is what has motivated us to design the world’s fastest CT, by
utilizing Dual Source for Flash-like scan speeds of up to 458 mm/s.

With Flash Spiral scanning, holding breath and motion lose their
significance, making the SOMATOM Definition Flash the optimal patient-
friendly CT. We introduce you to the new, cutting-edge of FAST CARE
technology that raises the standard of your patient-centric productivity,
e.g. through FAST Cardio Wizard, that breaks down the restrictions of
previous CT scanning in cardiology. Today, split-second scanning is
proving its value in actual practice. Emergency department trauma scans
of an entire body in less than five seconds with dose usually under 5 mSv
have also been made possible by the Flash’s speed. Now, with the help of
the FAST Spine feature, making the preparation of complex vertebrae
and disc reconstructions a matter of one click and 30 seconds, we take
trauma imaging and neurological CT examinations to the next efficiency
level for earlier and more accurately targeted treatment.

Defining
Low Dose CT
Applying the lowest radiation dose possible is of the utmost importance
for both you and, of course, your patients. Therefore you always want
to be assured that you have taken every means available to protect your
patient from unnecessary radiation. This desire lies at the heart of
our CARE (Combined Applications to Reduce Exposure) research and
development philosophy. Consequently, with Siemens’ continuing effort
to achieve highest dose protection, the new SOMATOM Definition Flash
now combines all features to reduce radiation as low as possible: next to
its already outstanding dose protection portfolio from the initial product
generation, it now adds a wide range of new and improved dose
reduction features.

CARE kV, for instance, is the industry’s first tool for automatically solving
the complex equation for optimal image quality at lowest possible dose
for each individual CT exam while considering tube voltage, tube current,
and contrast changes at different voltages and attenuation. This allows
you to benefit from the industry’s widest tube voltage range – not only
140 kV for bariatric imaging but now, if necessary, also down to 70 kV
where the Definition Flash sets new standards in pediatric safety.

Add the first, raw-data-based iterative reconstruction SAFIRE* and define
low dose for all body regions to take best care of your patients well-being.

34 Dual Source DE for all patients

Dual Source DE
for all Patients
It has always been a CT goal to collect as much information as possible in
order to differentiate tissues. With Dual Energy scanning, the SOMATOM
Definition and SOMATOM Definition Flash open the door to a new world
of characterization, visualizing the chemical composition of material. The
idea of Dual Energy is not new to the CT community. Earlier approaches,
including two subsequent scans at different tube voltages or two
subsequent scans at the same position, failed to seamlessly align the
imaged anatomy and to capture the same phase of contrast
enhancement.

Dual Energy was first successfully introduced into clinical practice with
Dual Source CT, i.e. two X-ray tubes and two UFC (Ultra-Fast Ceramic)
detectors mounted at 90 degrees from each other and perfectly
synchronized during scans. And, to date, Dual Source remains the only
modality that enables the usage of Dual Energy in daily practice at a dose
comparable to a conventional 120 kV scan and with optimum spectra
separation for highest value DE information.

With 12 FDA-cleared applications and more than 700 Dual Source CTs
installed, the number of Dual Energy scans has skyrocketed worldwide
and is expected to continue increasing at an even higher rate. Dual
Energy with Dual Source CT adds the decisive diagnostic confidence for
sustainable and sound treatment decisions – it is the advantage that
proves itself over and over in daily practice.
