Dosimetry for optimisation of patient protection in computed tomography.
Appl. Radiat. Isot. 50, 165-172 (1999)
The complex conditions of irradiation in computed tomography (CT), involving highly-collimated X-ray beams, necessitate the use of specially-defined dose descriptors such as the computed tomography dose index (CTDI). When used in a weighted form (CTDIW), this concept can describe the absorbed dose from a single slice in standard head and body phantoms. The model can easily be extended to characterise patient exposure for a complete examination by means of the reference dose quantity dose-length product (DLP). Effective dose can also be estimated from DLP, when required.
