Flash CT is the world’s fastest tomography device which emits the lowest dose of radiation. It produces cardiac and lung scans in particular as well as images of almost all other parts of the body. As the device uses low doses of radiation and scans rapidly, it is especially instrumental in cardiac check-up programs. The Flash CT provides a full body tomography in just 4 seconds, a cardiac angiography in 0.25 seconds and a lung scan in 0.6 seconds without the patient having to hold his/her breath. The Flash CT is especially beneficial for trauma patients, pediatric patients and obese patients due to the freedom of movement during the scan and its rapidity.
