Abstract:
The technological advances in computed tomography (CT) scanners and their continuously increased use have raised concern about the patient-induced risks from the CT procedures. In the present review, all available dose metrics used in CT dosimetry are described, evaluated, and compared. The various models and methodologies currently existing for the estimation of the effective dose and, by extension, the carcinogenesis probability as well as the way that this is derived from dose descriptors are also considered.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
