2. COMPUTED TOMOGRAPHY
 1972- Godfrey hounsfield of great
britian
 CT is accomplished by passing a
rotating beam of X rays through the
patient and measuring the
transmission
 The data are handled by a computer
that calculate the x ray absorption
 Compare with plain xrays CT uses
about 10 to 100 times more radiation 2
