Radiochirurgia Zagreb uses Siemens SOMATOM Definition Edge CT device with ultra low radiation dose for fast computer tomography with 384 reconstructed slices.
With around a quarter of therapies adjusted after response assessment, a key challenge in oncology is finding out if the tumor is responsive to therapy.
SOMATOM definition Edge is making therapy response assessment faster, more reliable, and easier to manage which makes the process easier for doctors and for patients as well.
Oncology
With around a quarter of therapies adjusted after response assessment, a key challenge in oncology is finding out if the tumor is responsive to therapy. Making therapy response assessment faster, more reliable, and easier to manage directly benefits the workforce as well as the patients. Investing into a higher quality therapy that uses smaller radiation doses and an early stages tumor locating capabilities using a CT device gives this technology a greater role in preventive care, as well.
The new SOMATOM Definition Edge enables excellent tissue evaluation, allows for the scanning of pediatric and obese patients without dose discussions, and facilitates a minimized sedation and breath hold

Cardiology
Covering greater volumes faster, improving contrast media efficiency in low kV TAVI planning, and introducing reliable, high-speed triple rule-out scanning expands the clinical capabilities.
The Stellar detector
Lower signal, lower voltage, lower dose - the new Stellar detector at the same time improves patient healing and reduces risk without compromising display quality and diagnostic assessment. Based on full electronic integration, Siemens' exclusive TrueSignal technology significantly reduces interference and cross-talk.
STRATON™ tube sa z-Sharp
STRATON ™ tubes with z-Sharp ™ technology and its revolutionary design based on direct anode cooling eliminates the need for heat retention and provides true temporary resolution up to 150ms and a high isotropic resolution of 0.33 mm for any scan, rotation speed and from any position within scanned area. This allows, for example, a significant reduction in moving artifacts in the heart to perform accurate stenosis measurements or stent planning with extreme precision.
SAFIRE tehnologija
With SAFIRE technology, Siemens has set a low-dose display scale with iterative reconstruction based on raw data. For the first time, synogram data is used in the process of improving iterative representations. With this, SAFIRE can reduce the radiation dose by up to 60% and improve the display quality (contrast, sharpness and interference).
SAFIRE in 3 steps:
Multiple iterative loops derived in the raw data domain correct geometric imperfections and other artifacts
Reconstruction of an image from "corrected" raw data
Multiple iterative loops performed in the image domain eliminate image noise due to the final and excellent image quality
For the first time, raw data (or sinogram data) is actually used in an iterative image enhancement process. With this, SAFIRE can achieve a significant reduction in radiation dose1. Or improve image quality (contrast, sharpness and noise) instead, even surpassing the already impressive image quality achieved with IRIS
Features and benefits:
- Up to 60% dose reduction
- Superior image quality
- Fast and customizable workflow with> 20 frames per second
ADMIRE (Advanced Model Iterative Reconstruction)
The lower the dose, the more difficult it is to reconstruct the images with satisfactory quality - this is a common rule in CT. But with ADMIRE technology, the latest generation of iterative reconstruction, physicians and radiologists have access to increased display quality with a natural impression and all clinical applications with such a low dose level that exceeds all expectations.
TwinBeam Dual Energy
TwinBeam Dual Energy, a new dual-energy meter from the same source, enables simultaneous acquisition of high and low kV data sets and a single CT scan, enabling high-contrast dynamic applications. By creating dose-efficient and comprehensive Dual Energy capabilities routinely applicable to almost all patients without compromising on display quality, the new SOMATOM Definition Edge provides greater versatility than any other single-source CT system. TwinBeam Dual Energy allows simultaneous acquisition of high and low energy spectrum that allows additional diagnostic information without increasing the dose. With TwinBeam Dual Energy, response to therapy can be assessed faster, easier, and more reliably.
FAST CARE aplikacije
FAST CARE technology exceeds expectations in both essential dimensions of CT - obtaining reliable results with minimal radiation exposure and speed in obtaining the same..
Adaptive 4D Spiral Plus
The SOMATOM Definition Edge features an Adaptive 4D Spiral Plus for wide-range dynamic displays up to 48 centimeters. This means that it allows not only the delineation of the aneurysm but also the identification of the source of bleeding and the assessment of venous thrombosis.
TrueSingal technology
The lower the signal, the higher the interference, which means the lower the display quality? That is no longer true. Based on the complete electronic integration of the Stellar detector, TrueSignal technology significantly reduces electronic interference, especially in low kV displays. The signal-to-noise ratio has been improved many times over, and low-signal data sets benefit from increased sharpness and clarity because the detector can now differentiate much better between individual voxel signals and surrounding data displays.
iMAR (Iterative Metal Artifact Reduction)
Metal implants cause artifacts that often result in displays of such low quality that they cannot be used in diagnostics, which means that more planning time must be spent and the outcome of the therapy itself can potentially be compromised. iMAR is currently the most efficient algorithm focused precisely on the removal of metal artifacts for improved quality of diagnostic displays.
