SU‐FF‐I‐67: Converting CT Dose Length Product (DLP) to Kerma Area Product (KAP)
Medical Physics, 2009Purpose: The amount of radiation that is incident on patients in CT is measured using the Dose Length Product (DLP mGy‐cm) which is not commensurate with the corresponding quantity currently used in radiography and fluoroscopy, namely the Kerma Area Product [KAP].

We developed a k-factor-creator software (kFC) that provides the k-factor for CT examination in an arbitrary scan area. It provides the k-factor from the effective dose and dose-length product by Imaging Performance Assessment of CT scanners and CT-EXPO.

The purpose of this paper is to reappraise the accuracy of a conversion coefficient (k) reported by International Commission on Radiological Protection Publication 102 Table A.2. The effective doses of the routine head computed tomography (CT), the routine chest CT, the perfusion CT, and the coronary CT were evaluated using the conversion coefficient ...

Journal of the American College of Radiology, 2015
As CT use steadily rises, concern over potential risks of radiation exposure from medical imaging has received increasing attention. Since May 2011, the ACR Dose Index Registry (DIR) has been open for general participation and has been collecting CT radiation dose data from an increasing number of facilities of various types.

Comparison of Dose Length Product during 64 Detector And 256 Detector Cardiac Computed Tomography
2011Purpose: Radiation dose during cardiac computed tomography angiography (CTCA) can be minimized by using a prospective gating (step and shoot) scan mode. There is little data comparing this scan mode between systems.
