Purpose/Objective:

MRI guided radiotherapy (MRIgRT) using the Elekta Unity MR Linac (MRL) (Elekta AB, Stockholm, Sweden), has opened promising opportunity for hypofractionation, dose escalation and potential of reduced target volume margins in adaptive prostate radiotherapy. In conventional adaptive MRL workflows, the responsibility of online contouring of target volumes and OAR lies with the clinician, yet this approach poses challenges in terms of resource intensity. Alongside delegation of plan approval to physicists, a way to alleviate this is through a shift towards entrusting therapeutic radiographers (RTT) with the task of online target volume contouring.
