Development of a Knowledge Based Model (RapidPlan) for Brain Metastasis Stereotactic Radiosurgery and Validation with Automated Non-coplanar Treatment Planning (HyperArc)

Abstract

marker offsets was 0.38 mm (range, 0.24-0.61 mm). Angular dependences of the offsets on gantry and couch rotations were not found. Conclusion: We performed the clinical commissioning and evaluated the localization accuracy of the novel patient positioning system. We have demonstrated that this system has a competent performance in terms of the high localization accuracy and low radiation dose for brain stereotactic radiotherapy.

Early Changes in Serial CBCT-Measured Parotid Gland Biomarkers Predict Chronic Xerostomia After Head and Neck Radiation Therapy

“…As treatment regimens become more personalized, it becomes more important to form accurate risk assessments. Additionally, with the establishment of novel streamlined radiotherapy planning and delivery modalities (10–12), the ability to adapt treatments based on physiological changes during the course of treatment is now practical (13, 14). However, existing normal-tissue complication probability (NTCP) models are based on planned biological dose-volume characteristics, which do not adequately address inter-patient or intra-treatment variation.…”

Leveraging intelligent optimization for automated, cardiac-sparing accelerated partial breast treatment planning

“…While novel platforms such as RapidPlan and HyperArc (Varian Medical Systems) have provided a means of automating planning processes (11,12), many institutions still heavily rely on iterative, manual planning (13,14). Developing alternatives to manual planning would be ideal as the time required to train personnel and manually generate high-quality treatment plans remains costly (15).…”
