Workflow evaluation of surface-guided initial patient set-up in radiotherapy.

ABSTRACT:

Background and purpose

The desire to avoid tattooing radiotherapy patients lead us to implement surface-guided initial patient set-up (SGRT). To validate SGRT we investigated setup precision, user attitude, and impact on radiotherapy technician (RTT) workflow.

Materials and methods

During a six-month period, initial setup was investigated on six linear accelerators (Truebeam, Varian), each equipped with a thermo-optical surface camera (ExacTrac Dynamic, Brainlab). Precision was assessed by comparing couch shifts based on x-ray imaging acquired after initial setup and number of x-ray imaging procedures for each fraction to data from the prior year, using a tattoo-based setup. The data was split into subgroups (thoracic, abdominal/pelvic, palliative and miscellaneous (gastroin
