Evaluation of a Novel Atlas to Reduce Variability of Contouring Masticatory Muscles in Head and Neck Cancer Patients

Trismus is caused by damage to the masticatory muscles resulting from cancer or its treatment. Contouring these muscles allows avoidance planning to reduce radiation related toxicity. Clinician contouring is however undermined by inter-observer variability. A validated contouring atlas for the masticatory muscles would help standardise volumes, reduce inter-observer variability and improve accuracy. This study aimed to evaluate a novel in-house...
