ultrafast CT

electron beam tomography (EBT),

computed tomography in which the circular motion of the x-ray tube is replaced by rapid electronic positioning of the cathode ray around a circular anode, allowing full scans in tens of milliseconds.
Synonym(s): ultrafast CT

ultrafast CT

Imatron Imaging A CT imager that captures images in microsecs vs secs for conventional CT; the ↑ in speed eliminates the artifacts created by organ movement, making UCT ideal for evaluating coronary artery disease and other forms of heart disease. See Computer tomography.

This 15-year study is the first to evaluate the relationship of the heart disease risk factors measured before menopause (premenopause) and the extent of subclinical disease in the coronary arteries and aorta as measured after menopause (postmenopause) by a new and under-utilized technology, electron beam computed tomography (EBCT), otherwise known as ultrafast CT.
