First day of treatment

On the first day of treatment, we acquire AP and lateral films and compare them with DRRs to verify the patient setup before treatment.
  • If the films are approved, we acquire video images from cameras permanently mounted in the treatment room. The video images are used as reference images for online setup correction on all other treatment days. If video is not available, electronic portal imaging could be used for online setup correction.
  • Time to preport, verify setup and treat = 30 min.
