Embodiment Construction

[0042] According to one aspect of the present invention, a method of radiation dosimetry is described which facilitates determination of a dose response in a manner which takes into account variations in the thickness of a radiation-sensitive material. According to a particular embodiment, the dose response can be calculated using at least two component channels, in particular using two color channels of a flatbed color scanner. The method thus allows splitting the measured response into two parts, one dose-dependent and the other dose-independent. The dose-independent portion contains values ​​proportional to the thickness of the radiation-sensitive layer. This section can be used to correct dose responses derived from radiation-sensitive active ingredients to account for variations caused by differences in active ingredient thickness.

[0043] The term "image" as used herein refers to digital data corresponding to a scanned sample. Digital data can be raw values ​​obtained...

Abstract

A radiation dosimetry method and associated devices for carrying out the method are disclosed herein. More particularly, a method and associated apparatus which compensates for variations in amounts of a radiation sensitive material in a radiation dosimetry film is provided.

Description

technical field [0001] The present application relates to a radiation dosimetry method and related devices for performing the method. More specifically, the present invention relates to methods and related apparatus for compensating for variations in the amount of radiation-sensitive material in a dosimetry film. Background technique [0002] In facilities where radiation-emitting sources are used, such as in hospitals where cancer patients receive radiation therapy or in blood banks where blood products are irradiated, various methods are used to quantitatively determine the radiation dose delivered by the source. Methods used in practice include the use of thermoluminescent dosimeters (TLDs), ionizing radiation detectors, photographic film, and radiochromic materials. TLDs are inconvenient to use because they require a complex and time-consuming readout process. Ionizing radiation detectors are difficult to use, bulky and require complex setup. Photographic film require...
