What is CAD?
CAD, computer aid diagnostics is provided with all screening mammography examinations at all TRA outpatient imaging locations. CAD involves the use of sophisticated computer programming to analyze medical images following initial interpretation by a radiologist. It is estimated that use of CAD can improve diagnostic accuracy of a mammogram examination by 15 to 20%.
CAD (or CADD) stands for Computer-Aided Design & Drafting. It differs from both paint and “draw” programs in that measurement is central to its abilities. A “paint” program lets you manipulate each pixel in an array of pixels that make up an image. If the overall picture shows a car and a building, there is no logical distinction between them – its just an array of colored dots you can manipulate with painting tools. A “draw” program goes a step further – it is composed of separate entities or objects, such as circles, lines, etc. It may provide facilities to group these into “car” and “building”, but the final result is still an image described in terms of its appearance on paper. A CAD program introduces the concept of real-world measurement. A car or building can be drawn as if it were life-size, and later arranged into sheets and printed on paper at any desired scale. Valid measurements may be taken from the drawing and they should properly correspond to the real world object, if t
