Clinical validation study (10–15 cases vs TPS) #4

Gates v1.0.0 and the publication.

• Acquire 10–15 IMRT/VMAT/SRS clinical QA films (EBT3 or EBT4)
• Compare all 4 methods against TPS reference dose (Eclipse or RayStation)
• Metrics: absolute dose error at central point, gamma 3%/3mm, method agreement
• Sensitivity analysis: lateral correction on/off, pre-irradiation scan, ROI placement
• Document scanner commissioning procedure (lateral correction, linearity)

Produces the dataset for the paper.
