Patient Specific Quality Assurance (PSQA) programs are essential for validating the dosimetric accuracy of intensity modulated radiation treatment plans (IMRT, VMAT, etc). Numerous publications from COMP and AAPM highlight the significance of PSQA and offer guidance on establishing comprehensive PSQA programs. Traditionally, PSQA has been primarily measurement-based, involving the comparison of measurements to treatment plans recalculated in a phantom geometry and/or array detector. However, this method has several limitations and strains institutional resources, especially with the increased use of IMRT/VMAT over the past decade. New PSQA approaches have been developed to enhance the effectiveness of PSQA while reducing the resource burden. This continuing education session aims to review the current PSQA practices in Canada, evaluating the benefits and drawbacks of different methods, with a focus on ensuring
