Using Monte Carlo simulations and the ACE system, to which the group has access thanks to the Elekta-La Fe-UV collaboration, we will proceed to locate systems where the formalism currently used in high-rate brachytherapy treatment planning is no longer valid.
Characterisation of electronic brachytherapy systems using Monte Carlo techniques. The response of commercially available ionisation chambers will then be calculated in order to obtain the correspondence factors that will allow their use in clinical practice.
The first step consists of migrating to C++ CUDA. Next, the numerical techniques needed to use it as an inverse scheduling algorithm will be improved. The final step would be to include it in a planning system and verify it in clinical practice.
Research activity in this line of research focuses on the design and development of instrumentation circuits for signal conditioning in medical physics and biomedical technology. Research is currently being carried out in the field of detectors in intraoperative radiotherapy.
Once the development of effective algorithms has been completed, the necessary computed tomography-ultrasound fusion-strain techniques will be implemented. They will then be implemented in a commercial planning system and clinically verified.
The following beams will be studied: 6 MV, 12 MV, Esteya, HDR & LDR brachytherapy source; the chambers of PTW: Soft X-Ray Chamber Type 23342, 23344 and 34013, Farmer Chamber Type 30010, 30011, 30012 and 30013, Semiflex Chamber Type 31010, 31013 and 31021, Roos Chamber Type 34001 and Advanced Markus Chamber Type 34045.
