BIOB33H3 Chapter Notes - Chapter 1: Spiral Computed Tomography, Axial Skeleton, Appendicular Skeleton
Document Summary
Provide detailed information about internal systems and structure. Include noninvasive techniques that use radioisotopes, radiation, and magnetic elds to produce images of internal structures. Radiologists - physicians who specialize in the performance and analysis of diagnostic images. A high energy radiation that can penetrate living tissues. X-ray beams travel through the body and hit a photographic place (some are absorbed & some are de ected) Air, fat, liver, blood, muscle, bone (order of increasing radio density) Very radio dense, and the contours of the gastric and intestinal lining can be seen outlined against the white of the barium solution. Use a single x-ray that rotates around the body. The beams strike a sensor monitored by a computer. The rotation of x-ray around the body happens repeatedly which allows the computer to reconstruct a 3d structure of the body. Monitor blood ow through speci c organs (brain, heart, lungs, kidney)
