Treatment time and learning curve analysis of 1.5 T MR-Linac workflows led by radiation oncologists or therapists.

ABSTRACT:

Background and purpose

This study assessed the treatment time of online adaptive (i.e. Adapt-to-Shape, ATS) and virtual couch shift (i.e. Adapt-to-Position, ATP) magnetic resonance guided radiotherapy (MRgRT) on a 1.5 Tesla MR-Linac. Additionally, the transition from a radiation oncologists (RO)-led to a radiation therapist (RTT)-led workflow, and the presence of a learning curve were assessed.

Materials and methods

This study was conducted utilizing the prospective Multi-OutcoMe EvaluatioN of radiation Therapy Using the MR-Linac study (MOMENTUM, NCT04075305). Mean (±standard deviation) online adaptation time and total treatment time were collected from MR-Linac log files. Learning and proficiency phases were defined using a cumulative sum (CUSUM) analysis. Independent T-tes
