We will perform a phase I observational trial investigating the feasibility of the Markerless Tumour Tracking technology. Markerless Tumour Tracking will be integrated with existing treatment machines to provide real-time monitoring of tumour motion during treatment delivery. Eligible patients are implanted with fiducial markers, which act as the ground truth for evaluating the accuracy of Markerless Tumour Tracking. The patients will undergo the current standard of care radiotherapy, with the exception that kilovoltage x-ray images will be acquired continuously during treatment delivery and used to calculate online Markerless Tumour Tracking. Markerless Tumour Tracking determines the mean tumour position calculated over the most recent 15 seconds and displays shifts exceeding 3 mm. The trial will be a single-institution study recruiting only at RNSH Radiation Oncology Department. As this trial investigates feasibility, our focus will be on estimating the proportion of treatment time in which the Markerless Tumour Tracking is within acceptable limits.
