three-dimensional images, including 3-D views of the blood vessels, in an instant.
A 40-slice scanner collects images covering 20 to 32 millimeters in a single pass and a tightly packed 64-slice device can cover about 40 millimeters at a pass, which takes 0.4 seconds. The technology has been particularly exciting for studying the beating heart, providing the first clear non-invasive images of the heart and its major vessels. The scans can be timed to use only images gathered between contractions, so that the heart and its vessels can be seen without the blurring caused by motion.
