Impact of eFOV CT distortion on surface‐guided radiotherapy registration: Phantom‐based analysis
This phantom study demonstrated that eFOV reconstruction can compromise SGRT alignment accuracy, particularly when beam centers are located near distorted regions. Alignment remained within clinically acceptable limits when reference points were sufficiently distant from distortion. These findings provide important baseline data under controlled conditions, and clinical validation with patient cohorts is warranted to confirm their generalizability.
