Official title
Evaluation of Tumor Motion Management Strategies in Radiotherapy Using 4D-MRI
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The main goal of this research is to characterize patient-specific respiration-induced tumor and surrogate motion to evaluate the accuracy and effectiveness of the surrogate-based motion management strategies currently used in clinics. Specifically, the investigators hypothesize that dynamic MRI (Magnetic Resonance Imaging) obtained over a temporal duration consistent with radiotherapy treatments will provide spatio-temporal information of both the tumor and surrogate, and therefore can serve as a means to assess the quality of the tumor motion tracking with the surrogate. To test this hypothesis, the investigators specifically propose to 1) track and characterize the tumor and surrogate motion with 4D (4 dimensional)-MRI and 2) evaluate surrogate-based motion tracking in a cohort of patients with thoracic tumors. External and internal surrogate-based strategies commonly used in clinics have not been appropriately validated. With the increasing adaptation of these surrogate methods for motion management, the proposed research addresses these urgent issues in clinical radiotherapy while providing a means to achieve patient-specific motion management.
