摘要： 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.

摘要： An embodiment of the present disclosure is directed to a radioactive source tracking system adapted to determine in real time a spatial position of a gamma source in a volume, including a set of spatially distributed position sensitive detectors operable in real time arranged about the volume. The system includes a real time computer system adapted to calculate the spatial position per time stamp of the gamma source in the volume based on respective signals generated by the position sensitive detectors. In addition, the radioactive source is represented by a 3D or 4D data stream in real time. Other embodiments of the present disclosure are directed to a method for tracking a radioactive gamma source and a computer program product for causing a processor to determine a real time 3D or a 4D spatial position of a gamma source.

摘要： A system for transporting a source for brachytherapy may include a source guide, a detector, and a controller. The source guide may be configured to guide a source transport for transporting the source, wherein the source guide includes at least one electronic tag. The detector may be configured to detect a frequency signal generated by the at least one electronic tag, wherein the frequency signal varies when the source transport is proximate to the at least one electronic tag. The controller may be configured to receive the frequency signal from the detector and determine a path of the source transport based on the frequency signal. A method for transporting a source used for brachytherapy may include detecting a frequency signal generated by at least one electronic tag associated with a source guide configured to guide a source transport for transporting the source. The frequency may vary when the source transport is proximate to the at least one electronic tag. The method may further include determining a path of the source transport based on the frequency signal.
