Computed Tomographic Angiography: Technical Considerations

ByJacobo Kirsch, Eric E Williamson, Dominik Fleischmann

The basic concept of computing a cross-sectional image from

multiple x-ray projections to create images of an anatomic

structure has remained the fundamental principle of com-

puted tomography (CT) since its origin in 1971. The evolu-

tion of this powerful tool has been spearheaded by hardware

and software advances that allow for rapid, robust acquisi-

tion of scan data and prompt, flexible workstation display.
