Use of a novel anthropomorphic prostate simulator in a prostate brachytherapy transrectal ultrasound imaging workshop for medical physicists

•Image guidance is fundamental to low dose rate prostate brachytherapy.•Ultrasound imaging training is not required in radiation oncology training.•Simulation based training is an effective approach to ultrasound training.•Perceived and objective improvement in knowledge after ultrasound training workshop.•Potential for interdisciplinary training for the prostate brachytherapy team.
