Surface-guided radiotherapy supported frog-leg vulvar treatment setup
Surface-guided radiotherapy kept mean setup shifts near zero during frog-leg vulvar volumetric modulated arc therapy.
Thermo-optical surface guidance supported breast deep inspiration breath-hold radiotherapy setup
Thermo-optical surface monitoring with X-ray correction kept breast deep inspiration breath-hold setup errors within clinical tolerance.
Surface scans showed modest average but substantial individual breast deformation during radiotherapy
Mean treated-breast displacement was 1.6 mm, with larger patient-specific changes near treatment completion and during follow-up.
Monocular surface imaging enables real-time breast dose reconstruction
Patient-specific surface imaging reconstructed breast radiotherapy dose with a 93.8% gamma passing rate and 42-millisecond latency without additional imaging radiation.
