Verification Based on 3D Fluoroscopic Treatment Imaging

Respiratory motion causes significant discrepancies between the planned and delivered dose for anatomy moving with respiratory motion. In this technique, 3D images are estimated continuously throughout treatment delivered, and used to reconstruct the delivered dose to the tumor and healthy tissue. This animation shows anterior-posterior kV projections used to estimate 3D images, and the corresponding accumulated dose over time

This flow chart outlines the methods used to estimate the delivered dose
