Until now, many CT vendors have fallen prey to unnecessary dose both before and at the end of the spiral scan range, which has been a function of spiral multi-slice imaging. As detector size and slice counts grow, the "pre and post over scan range" problem becomes more acute, particularly where older gantry designs are simply updated with newer detector designs to save cost for the manufacturer. Only Siemens' unique Adaptive Dose Shield addresses this growing issue by dynamically blocking the unnecessary dose before and after the spiral scan, ensuring that the only dose applied to the patient is dose that is clinically relevant.
The SOMATOM Definition AS adapts to each patient's clinical situation and also opens the door to new applications in CT imaging. The unique Adaptive 4D Spiral mode of the SOMATOM Definition AS is able to address functional imaging (perfusion images of blood flow over time) of whole organs. This allows Siemens to offer dynamic information of up to 27 cm. In the case of a stroke, physicians can use whole-organ perfusion imaging not only for a small part of the brain, but for all of it.
"A SOMATOM Definition CT scanner transforms itself into a stroke unit, a noninvasive cath lab, a therapy management tool for cancer patients, or an interventional suite - all according to the need of the individual patient," said Kingma. "All of these advances work to improve the quality of patient management and overall efficiency of healthcare, while keeping the costs down."
"Clinical needs have shifted and we have seen a significant upswing in the number of patients who undergo bariatric surgery," said Schoepf. "In the past, we were limited by the bore size and the table weight, but the SOMATOM Definition AS allows us to adapt to the needs of this group of patients."
