A reconfigurable detector for measuring the spatial distribution of radiation dose for applications in the preparation of individual patient treatment plans

In this work, a novel reconfigurable Dose-3D detector intended for a full spatial therapeutic dose measurement to improve radiotherapy treatment planning is presented. The device is composed of a reconfigurable detection phantom allowing patient-centric adjustments to its geometry, a scalable data acquisition system (including hardware, firmware, and low-level software) designed to change with the phantom's configuration seamlessly, and a high-level software package for tumour geometry extraction based on computer tomography scans. Extracted geometry will be used in the Monte Carlo simulations and the configuration of the phantom. Each of the components to be used in the measurement system has been assessed obtaining the following results. The scintillating voxels' light output is sufficient. The data acquisition system with its hardware and software has been tested using artificial testing signals and laser light proving a reliable and robust means of physics data reconstruction.
