Miscellaneous
Dose Area Product Calibration
The following paragraphs explain how to use the Remote Utilities Tool to calculate the Dose Area Product (DAP). DAP is a
calculation of surface dose at a given distance from the X-ray tube multiplied by the surface area receiving the dose. DAP is
equal for all planes that are perpendicular to the beam axis.

Note: DAP is a measurement of radiation from the X-ray tube, and does not represent the radiation being absorbed by the
patient.
