Figure 1. A clear reduction in inter-individual contouring variability was observed when comparing the delineations of the participants during the first training session (m1) and the second one (m2), as illustrated for the corpus callosum, amygdala, and thalamus. Conclusion Explanatory movies were developed with the aim of reducing inter- and intra-individual variability in the delineation of the 10 OARs introduced in the updated EPTN atlas. These movies will be made available on www.cancerdata.org.

Materials and Methods McMedHacks is a free and student-led 8-week summer program. Registration for the event was open to everyone, including a form to survey participants’ area of expertise, country of origin, level of study, and level of programming skills. The weekly workshops were instructed by 8 students and experts assisted by 20 mentors who provided weekly tutorials. Recent developments in DL and medical physics were highlighted by 21 leaders from industry and academia. A virtual grand challenge Hackathon took place at the end of the workshop series. All events were held virtually and recorded on Zoom to accommodate all time zones and locations. The workshops were designed as interactive coding demos and shared through Google Colab notebooks. Results McMedHacks gained 356 registrations from participants of 38 different countries (Fig. 1) from undergraduates, to PhDs and MDs. A vast number of disciplines and professions were represented, dominated by medical physics students, academic, and clinical medical physicists (Fig. 2). Sixty-nine participants earned a certificate of completion by having engaged with at least 12 of all 14 events. The program received participant feedback average scores of 4.768, 4.478, 4.579, 4.292, 4.84 out of five for the qualities of presentation, workshop session, tutorial and mentor, assignments, and course delivery, respectively. The eight-week long workshop’s duration allowed participants to digest materials taught in a continuous manner as opposed to bootcamp-style conference workshops.
