We can conduct the coronary artery calcium (CAC) score test, coronary computed tomography angiography (CTA), abdominal computed tomography examination (livers and pancreas), and low-dose computed tomography (LDCT) screening using our CT640 ultra-fast computed tomography scanner. We were the first one to have invented a non-invasive and fast test to accurately detect and screen for the hardest-to-find blocked coronary arteries, early-stage lung cancers, hepatic cancers, and pancreatic cancers with the use of a non-ionic contrast agent only once. The whole set of tests are completed at one go. The radiation dose of a CT640 ultra-fast computed tomography scanner is very low, which has a minor impact on human health.
