SOMATOM Definition

Siemens’ SOMATOM® Definition is the world’s first dual-source computed tomography (DSCT) system. This CT system uses two X-ray sources and two detectors at the same time at different power levels, compared to all other CT systems that use only one set. The result is two data sets with diverse patient information, which allows doctors to differentiate, characterize, isolate and distinguish body tissues and fluids, leading to new breakthroughs in medical imaging.

SOMATOM Definition

This clinical image was acquired using the SOMATOM® Definition from Siemens Medical Solutions. A patient with known chronic obstructive pulmonary disease and contraindication for beta blockers was scanned to diagnose the reason for a sudden onset of acute atypical chest pain. The patient's shortness of breath made a scan time below 10 seconds necessary, and a temporal resolution of constant 83 milliseconds allowed motion-free imaging of a varying heart rate from 85-93 beats per minute.

SOMATOM Definition

This clinical image was acquired using the SOMATOM® Definition from Siemens Medical Solutions and shows motion-free imaging of the left coronary and circumflex arteries. With the Definition, even smallest side branches of the coronaries can be visualized. The patient was admitted with atypical chest pain under exertion. A six-second cardiac CT scan was performed to rule out coronary artery disease. The heart rate during the scan varied from 79-86 beats per minute.

SOMATOM Definition

This clinical image was acquired using the SOMATOM® Definition from Siemens Medical Solutions and shows a comparison of the right coronary artery in diastole (phase of cardiac filling) and systole (phase of cardiac contraction). The right coronary shows the highest range of motion during the cardiac cycle and thus can be difficult to image. It can be clearly seen that the right coronary artery is displayed without motion artifacts in both phases. The patient was admitted with atypical chest pain under exertion. A six-second cardiac CT scan was performed to rule out coronary artery disease. The heart rate during the scan varied from 79-86 beats per minute.

SOMATOM Definition

This clinical image was acquired using the SOMATOM® Definition from Siemens Medical Solutions and shows a comparison of the left coronary artery and circumflex artery in diastole (phase of cardiac filling) and systole (phase of cardiac contraction). Normally, only images from the relatively motion-free diastolic phase can be used for CT imaging. Due to the superior temporal resolution of the SOMATOM Definition, all cardiac phases can be displayed without motion artifacts. The patient was admitted with atypical chest pain under exertion. A six-second cardiac CT scan was performed to rule out coronary artery disease. The heart rate during the scan varied from 79-86 beats per minute.

SOMATOM Definition

This clinical cardiac image was obtained on the Siemens SOMATOM® Definition – the world’s first dual source computed tomography (DSCT) system – at a heart rate of 130 beats per minute. The SOMATOM Definition provides visualization of even the smallest coronary arteries without motion artifacts even at elevated heart rates.
