Abstract
One embodiment of the present disclosure is directed to a mobile X-ray unit. The mobile X-ray unit may include an X-ray applicator for emitting an X-ray beam for irradiating an object. The mobile X-ray unit may further include a phantom-based dosimetry system configured to perform a dosimetry check of the X-ray beam. The phantom-based dosimetry system may include two sets of dose meters, each set being positioned on a surface at a distinct depth. The mobile X-ray unit may also include a dosimetry control unit configured to receive measurements from the two sets of dose meters and determine whether the dosimetry check is passed based on the measurements.
Claims20
A mobile X-ray unit comprising:
- an X-ray applicator for emitting an X-ray beam for irradiating an object;
- a phantom-based dosimetry system configured to perform a dosimetry check of the X-ray beam, the phantom-based dosimetry system including two sets of dose meters, the two sets of dose meters being positioned on two parallel surfaces each at a different distinct depth with respect to a phantom;
- and
- a dosimetry control unit configured to receive measurements from the two sets of dose meters and determine whether the dosimetry check is passed based on the measurements.
A method for performing a dosimetry check using a phantom-based dosimetry system in a mobile X-ray unit, the phantom-based dosimetry system including two sets of dose meters, including a first set of dose meters positioned on a first surface at a first depth and a second set of dose meters positioned on a second surface at a second depth, the method comprising:
- measuring a plurality of dosimetry parameters using the two sets of dose meters, including a first dosimetry parameter indicative of a change of dose at the first depth and a second dosimetry parameter indicative of a change of dose at the second depth, wherein the first surface is parallel to the second surface, and wherein the first depth and the second depth are different with respect to a phantom;
- and
- determining whether the dosimetry check is passed based on the dosimetry parameters.
