A heterogeneous-cavity model for miniaturized detectors of orthovoltage X-rays Open
To meet the needs of modelling small-sized detectors of orthovoltage X-rays, for spatially fractionated radiotherapy, we propose a model to determine responses of the detectors in cases of highly heterogeneous cavity. The model was applied…
