A case study on SSD to SAD linear acceleartor calibration transition.

ABSTRACT:

Purpose

Modifying calibration conditions of linear accelerators is infrequent and potentially a high-risk procedure. This study outlines a systematic approach used to transition a linear accelerator's calibration condition in an active clinical environment from source-to-surface (SSD) to source-to-axis (SAD), while maintaining treatment accuracy and avoiding interruption of clinical operations.

Methods

A satellite clinic within a university radiation oncology service operated an Elekta Versa HD linear accelerator with SSD calibration, while other system C-arm accelerators used SAD. With a single installation of the treatment planning system used across all sites, it was decided to convert the machine to SAD calibration. Representative plans with diverse delivery techniques w
