The aim of this research project is to develop and implement methods for the estimation of energy dose rates inside of X-ray fields in the context of computational radiation protection dosimetry. Specifically, we aim to develop sophisticated real time alternative methods for Monte-Carlo-Simulations that are commonly used in this field. Faster methods in this area are gaining relevance as there are ongoing efforts in real time computational dosimetry for certain workplaces to enhance the legal dosimetry for occupationally exposed personnel. Computational dosimetry in general is useful, when the environment is fully specified and the dose rates are spatially varying. The specific case for this project is the doses received by medical personnel during minimal invasive cardiac surgeries. For that application, we also aim to develop useful feedback to the personnel utilizing audio-visual signals as well as a spatially resolved visualization of the energy transported by a specific radiation field for training purposes as well as for real surgeries. As a starting point for this project, methods from the volumetric rendering in the field of real time computer graphics shall be examined. In particular, this work will focus methods based on the recently popularized technique of neural rendering.
