DICOM interface and visualization tool for Geant4-based dose calculation

摘要

We developed a DICOM interface and a visualization tool for Geant4-based medical physics applications for the use of dose calculation, in particular to radiotherapy in purpose of accurate full-simulation of particles propagating and interacting with not only medical devices but also patient tissues. DICOM is commonly used to transport digital images such as patient image information in the above-mentioned domains. With the DICOM interface, we succeeded in retrieving various manufacturers' DICOM data stream, constructing Geant4 geometry and simulating particle interaction with patient tissues in our Geant4-based application. The visualization tool provides volume rendering and fusion of patient image and calculated dose distribution.
