What this trial studies

This study evaluates the feasibility of various new techniques and software for MR-guided adaptive radiation therapy, which allows for real-time monitoring and adjustment of treatment based on changes in tumor and organ positions. By integrating imaging directly at the linear accelerator, the study aims to enhance the precision of radiotherapy and reduce toxicity to surrounding healthy tissues. It involves multiple parallel cohorts of patients treated with radiation therapy on the MR-Linac, with a focus on collecting data on acute toxicity and treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are undergoing radiation therapy and meet specific health criteria.

Not a fit: Patients with contraindications for MRI, those who are pregnant, or individuals with severe claustrophobia may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve the accuracy and safety of radiotherapy for patients with tumors.

How similar studies have performed: Other studies have shown promise with MR-guided adaptive radiotherapy, indicating potential for success in this approach.
