Summary

A more recent competing technology for implementing the DIBH technique is real-time surface photogrammetry using the AlignRT system (Vision RT Ltd., London, UK). AlignRT system use non-ionization near infrared light to track patient surface motion. The system has one projector projecting near infrared optical pattern on patient surface. The optical pattern is imaged by optical cameras (two per pod) at \~25 Hz. The user selects a region-of-interest (ROI) on the surface and the software calculates and displays the real-time position in six degrees (3 translations and 3 rotations) in real-time. Once the patient has matched the pre-determined DIBH position (within threshold accuracy), the radiation beam is enabled to be turned on for treatment.

Conditions

  • Thoracic Cancer
  • Abdominal Cancer

Interventions

DEVICE

Tidal volume measured by spirometer and DIBH surface from CT image

The SOC DIBH CT scan will be transferred to Eclipse treatment planning system for treatment planning. Tidal volume measured by spirometer and DIBH surface from CT image will be used as a reference surface for patient treatment initial setup. CBCT will be acquired before each fractional treatment for the patient alignment before beam delivery.
