Because the modules are self-directed, learners can complete them when they have available time in the clinic. Since these workshops teach basic planning concepts and skills, they should be completed in order: first AP/PA spine, then three-field breast, and finally IMRT (intensity-modulated radiation therapy). Learners do not need to complete a dosimetry rotation to learn conceptual and practical aspects of radiation treatment planning. The modules can be repeated to ensure that the concepts and practical aspects covered are fully understood. These modules have been completed by multiple radiation oncology residents and have received positive reviews. It takes approximately 1 hour to complete each module. Residents have consistently rated their comfort level and understanding of treatment planning as improved after completion of the modules. Educational Objectives By the end of the AP/PA spine module, learners will be able to: Open a treatment plan.Contour a target.Create a planning target volume (PTV) using an expansion.Set a treatment isocenter.Create a treatment field.Set beam borders.Prescribe a dose and number of fractions.Turn on isodose lines.Evaluate a basic dose-volume histogram.Change a beam energy.Copy and oppose a treatment field.Understand the concept of depth-dose curves.Understand dose volume histograms.Understand different beam energy and the effect on maximum dose.Understand gross tumor volume to PTV expansion and the significant increase in volume with a small PTV expansion.Understand single versus opposed beams and the effect on maximum dose. By the end of the three-field breast module, learners will be able to: Set two isocenters for the tangent fields and supraclavicular fields.Select tangent beam angles.Set the jaws for tangent and supraclavicular beams.Match the tangent beams and supraclavicular fields in a two-isocenter plan.Create a second treatment planning trial.Set the isocenter for a monoisocentric treatment plan.Compare two planning trials. By the end of the intensity-modulated radiation therapy (IMRT) module, learners will be able to: Set IMRT optimization parameters.Set planning objectives for the target volume and organs at risk.Use a ring structure to constrain the high dose region of an IMRT plan.Compare two IMRT trials.Understand targets and organs at risk.
