Course Material 


Prior to the workshop, participants will be provided a short clinical vignette about a post-operative prostate case. They will then prepare for the workshop by contouring the clinical target volumes (CTVs) on the provided CT Simulation dataset.

During the workshop, Dr. Chad Tang will go over the specified volumes, talk about why he contoured the way he did, and then compare the teachers’ contours with the participants and offer suggestions.


This program is designed to meet the interest of radiation oncologists and radiation oncology residents.


Each of the workshop sessions will last for two hours.  The session will cover the following areas:

  • (Pre-course) Access to platform and hands-on contouring by participants

  • Short talks each by sub-site surgeon, radiation oncologist and radiologist

  • Presentation of the case and delineation guidelines used

  • Breakout session to review participants’ contours in comparison to the reference contours

  • Summary of key points by expert panel 

  • Discussion between participants and experts

Learning Objectives

  • Describe clinical and anatomical rationale for the selection of clinical target volume and organs at risk delineation

  • To be familiar with areas at risk for recurrence after prostatectomy and of nodal dissection templates employed by urologists. 

  • Learn about the post-operative imaging modalities used to identify residual/recurrent tumour  

  • To be aware of the common pitfalls in delineation

  • To be updated of the latest available contouring guidelines
