Computed Tomography Technologist Practice Exam

Dose Length Product (DLP) is a specific measure used in computed tomography (CT) that quantifies the total radiation exposure a patient receives during a scan, taking into account both the dose of radiation per slice and the length of the scan in terms of the number of slices or the extent of the area being imaged. Essentially, DLP is calculated by multiplying the volume of the scanned area (irradiated length) by the dose of radiation delivered per unit length. This makes it a crucial metric for understanding and assessing the radiation risk associated with the imaging procedure.

In contrast, the other options — patient comfort, equipment operational efficiency, and technologist performance — do not directly relate to the quantification of radiation exposure during a scan. While these factors are important for overall patient care and workflow, they do not reflect the specific measurement that DLP provides in the context of radiation safety and dose management.
