Embodiment Construction

[0019] The following detailed description presents embodiments of the present disclosure by way of example and not by way of limitation. It is contemplated that the present disclosure has general application to embodiments of structures and methods for active measurement of radiation peak skin dose to a patient during a medical procedure. The measurement system is low cost, thin and flexible, and can be incorporated into the existing frame of the surgical system.

[0020] Embodiments of the present disclosure describe incorporating a dose measurement device or dosimeter within an examination table that generates an accumulated peak skin dose as a function of position with an approximate 2-3 millimeter (mm) to approximately 1 centimeter (cm) Size resolution. Dosimeters are substantially transparent to x-ray radiation, preventing only a small percentage of delivered dose. The dosimeter is placed in close proximity to the patient's skin to accurately measure effects such as sca...

Abstract

A method of imaging a patient and an X-ray dosimetry system are provided. The X-ray dosimetry system includes a support platform configured to support an object to be imaged and a digital X-ray dosimeter mounted on a surface of the support platform. The X-ray dosimeter is configured to receive incident radiation prior to the incident radiation having passed through the object to be imaged, the X-ray dosimeter comprising a thickness of less than about four millimeters.

Description

Background technique [0001] The present description relates to radiation detectors and, more particularly, to systems and methods for directly measuring a patient's peak skin dose on a patient table. [0002] During fluoroscopic medical imaging procedures, injury to the patient and / or physician due to overexposure to radiation can occur, and skin damage is a risk to the physician as well as the patient. In order to minimize the dose of radiation during such procedures, it is important to measure the peak dose delivered to the skin during the fluoroscopy procedure. However, measurement of peak skin dose has been challenging, and at least some known imaging systems do not include methods for tracking peak skin dose. Systems that include skin dose monitoring typically employ algorithmic and estimation techniques in order to estimate peak skin dose. This estimation involves tracking the patient position and the X-ray tube output to track the peak skin dose delivered to the skin....
