Developing a markerless tracking method for real-time tumor motion measurement during radiation therapy
Official title: LEARN: Learning Environment for Artificial Intelligence in Radiotherapy New Technology
Run by University of Sydney · NCT05184790 · Data updated 2026-11-12
This study is testing a new way to track tumor movement during radiation therapy without using markers, to see if it can help doctors target the treatment more accurately for cancer patients.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults receiving radiation therapy for specific cancers, including brain, breast, kidney, and prostate cancers, or cardiac arrhythmias.
✕Probably not a fit
Patients under 18 years of age or those not receiving radiation therapy at participating centers will not benefit from this study.

What this trial studies
This observational study aims to create a whole-of-body markerless tracking method to measure tumor and organ motion during radiation therapy. By utilizing routinely acquired patient data from 300 individuals with various cancers, the study will train, test, and validate this tracking method. The data will be processed through a clinical trial learning system that enhances the accuracy of the tracking software with each patient. The primary goal is to improve targeting accuracy in radiation therapy through advanced imaging techniques.
Why it matters
Potential benefit: If successful, this method could significantly enhance the precision of radiation therapy, leading to better treatment outcomes for patients.
How similar studies have gone: While the approach of using markerless tracking in radiation therapy is innovative, similar studies have shown promise in improving treatment accuracy.
Who can join: the full rules
Show full inclusion / exclusion criteria
Inclusion Criteria: * Will receive radiation therapy for brain, breast, head and neck, kidney, liver, pancreas, prostate, spine cancer treatment or cardiac arrhythmia treatment at a participating centre. * Will receive CT planning, and a cone beam CT scan for at least one fraction of radiation therapy. * Will receive intrafraction x-ray imaging for the liver, pancreas, prostate, spine cancer treatment or cardiac arrhythmia treatment. As intrafraction imaging is not common standard of care for brain, breast, head and neck and kidney cancer treatments there is no requirement to have intrafraction x-ray imaging data for these anatomical sites. * Provides written informed consent. Exclusion Criteria: * Less than 18 years of age
