The aims of this project were to (1) develop and apply a process to optimize 3D-printing processes specifically for tissue-equivalent small-field dosimetry phantoms and, (2) design and test a 3D-printed phantom for single-isocenter multi-target (SIMT) stereot...

Treatment planning system (TPS) beam modelling is identified as the largest cause of independent dosimetry audit failure. This study aims to develop and validate a universal beam model (UBM) specific to single-iso multi-target (SIMT) stereotactic radiosurgery...

During liver radiotherapy, respiratory-induced tumor motion can result in target underdose and increased irradiation of surrounding healthy tissue. Existing real-time image-guided approaches often require specialized equipment or invasive marker implantation...

Clinical practice in radiotherapy medical physics is strengthened through shared experience and peer learning. Although peer-reviewed outputs and educational resources are essential, they are often insufficiently timely, specific, or practical for day-to-day...

For single-isocenter multi-target (SIMT) stereotactic radiosurgery (SRS), benchmarking, auditing and inter-institutional standardization of dose delivery remains challenging as it requires specialized equipment and expertise. Electronic portal imaging devices...
