CT Boot Camp Section 1, CT Boot Camp Questions and Answers 100% Pass A single "view" acquired during a CT scan is also called a: -Projection A CT scanner collects several projections as the tube and detectors spin around the patient. Each of these projections represent a unique view of the anatomy that is eventually compiled together to form the 3D volume of data The main difference between image production in CT compared to image production in radiography is: -Projections are compiled into ...
