A parameter used as a surrogate measure for patient dose in a computed tomography scan of length L. By convention the DLP is reported in the units of mGy x cm and is the product of the energy deposited in a single slice (CTDIvol) multiplied by the scan length L. This quantity is analogous to the ‘kerma-area product (K<sub>ap</sub>)’ used in planar radiography.

A parameter used as a surrogate measure for energy imparted to the patient in a computed tomography scan of length L. By convention the DLP is reported in the units of mGy cm. See ICRU Report 87 (ICRU 2012) for more details.
