Appears to be a simple, fast, non-invasive, and reproducible method to analyze the set-up alignment in 3DCRT of prostate cancer patients.1

Surface imaging can detect setup errors predictive of registration errors measured by ultrasound. This data suggest that the two IGRT modalities could be considered as complementary to each other and could represent a daily "low-cost" and non-invasive IGRT modality in prostate cancer patients.2

SGRT decreased the translational magnitude shifts significantly (P < .05) by 0.5 ± 1.4 mm for pelvis. The quality of patient positioning before ion-beam treatments has been optimized by using SGRT without additional imaging dose. SGRT clearly reduced inefficiencies in the patient positioning workflow.3

The inter-fractional patient setup accuracy was significantly better using AlignRT compared to laser alignment with skin marks. Reducing the frequency of CBCT scans reduces imaging dose and overall treatment time.6
