What method is used to calculate patient dose in radiographic procedures?

The method used to calculate patient dose in radiographic procedures involves utilizing dosimetry data and exposure factors during imaging. This approach allows for an accurate assessment of the radiation dose received by the patient. Dosimetry data includes information on the amount of radiation emitted by the imaging equipment, while exposure factors incorporate variables such as the kVp (kilovolt peak), mAs (milliamperes per second), and distance from the source to the patient. By combining these elements, radiologic technologists can determine the effective dose that is delivered during each specific imaging procedure.

This calculation is critical as it facilitates the evaluation of radiation safety and the management of patient exposure, ensuring that it remains within the established guidelines and justifications for medical imaging. Relying solely on fixed doses, patient weight, or the number of images without considering these specific dosimetry data and exposure factors would not provide an accurate or appropriate measure of patient dose, as these factors can vary widely between different imaging scenarios and patients.
