An advanced scanning machine has just been released, capable of capturing images in less time than a heartbeat. The Somatom Definition features two scanning devices, allowing it to produce images of the body twice as fast as usual.

Siemens, the manufacturer, states that due to its high speed, this device is ideal for diagnosing cardiovascular diseases. It will be launched in the UK next autumn.
Scanning experts indicate that the “dual” imaging technology could reduce the need for additional invasive diagnostic techniques.
CT scan technology utilizes special X-ray equipment to capture images from various angles around the body. A computer then processes the information to produce cross-sectional images of tissues and internal organs. Traditionally, scanners only have one X-ray tube, with a single detector positioned directly in front. The scanner moves in a spiral around the patient, from head to toe, to generate comprehensive images. Currently, this type of machine can perform three rotations per second.
However, scientists aim to increase the rotation speed further, allowing for quicker overall examinations. This also means that patients will undergo scans more rapidly, freeing up time for additional patients.
According to Gunter Dombrowe, director of medical solutions at Siemens in the UK, it is technically impossible to make traditional scanners operate any faster. To address this issue, the Somatom Definition employs two X-ray tubes and two detectors. One tube starts at 0° and continues around the body to 90°, while the other tube begins at 90° and finishes at 180°, thereby halving the scanning time.
Dr. Dombrowe noted that this is particularly important when conducting heart examinations. Currently, CT scans of the heart require patients to be administered a medication to slow their heartbeat, producing clearer images. With the new scanning machine, doctors can capture nearly static images of the heart.
The first Somatom Definition was installed at the University of Erlangen in Germany.
