Description of intervention(s) / exposure
SeedTracker is a real-time position monitoring tool, developed in South Western Sydney Local Health District (SWSLHD), which works in conjunction with the software system in Elekta Linear Accelerators. The majority of prostate cancer patients undergoing radiotherapy have the radiopaque markers implanted in the prostate for pre-treatment position verification. The SeedTracker system monitors the prostate position during the treatment delivery in real-time by detecting the position of the radiopaque markers via monoscopic x-ray images acquired during treatment delivery.
Treating Radiation Therapists will use the SeedTracker in conjunction with the Linear accelerators, with Physics support to monitor the patient during their treatment delivery. This will be delivered daily throughout the prescribed treatment course (20 or 39 days) at the participating hospitals.
This study will assess the use of SeedTracker on patients receiving radiotherapy to the prostate in terms of safety and efficacy impacts to the department and patients through use of surveys and collated treatment delivery times. The study will also quantify prostate motion during treatment and corrections required for position deviations by recording daily data.
The study will analyse collected data to provide insight on any additional workload or resources required for the implementation of real-time position monitoring in conventional prostate radiotherapy and improve radiotherapy treatment delivery accuracy.

Secondary outcome [1] 349169 0
Impact and safety of introducing SeedTracker real-time position monitoring for prostate radiotherapy on departmental resources, scheduling and patient treatment time, will be assessed by the 'SeedTracker - User Evaluation Form' completed by treatment staff. This survey was designed specifically for this study. This is a composite outcome.

Statistical methods / analysis
Prostate Motion trajectory: The prostate motion trajectory during the treatment delivery of all the treatment fractions of all patients will be collected and recorded in SeedTracker system. The number and types of position deviations observed will be analysed to study the intrafraction motion patterns and frequency of position deviations in the studied cohorts of patients.
Treatment time: The overall treatment time for each treatment session with the SeedTracker real-time monitoring will be measured from the activity monitor in Mosaiq Record and Verify system. This time will be compared with the retrospective prostate cancer patients’ treatment activity time to quantify the impact of utilising the SeedTracker real-time monitoring system in departments’ human and treatment machine time resources.
Data for technical assessment of the SeedTracker system: Feedback and recommendations from the individual members of the multidisciplinary team from the participating centres will be collected on a weekly basis. Information on the technical and workflow aspects of the real-time position monitoring with SeedTracker system will be collected.
