Introduction to Computed Tomography exam CT founded in 1970 by Sir Godfrey Hounsfield who Developed the algorithms for the reconstruction of the images? Allan Cormack Localizer, also called scanogram, topogram, pilot or survey is the 1st C.T image of exam, or scout film Voxel ( 3D tissue element) The basic unit of computed tomography reconstruction, represented as a pixel in a computed tomography image display.
