Brief Summary:
This study is investigating measurement of prostate motion during radiotherapy using the implanted gold markers. If motion is greater than 3mm then the beam will be stopped and position corrected (gating).

Arm Intervention/treatment
Experimental: R/T gating kV intrafraction monitoring

Intervention: Recruitment will be performed in 2 phases:

Phase I will include the first 10 patients. All patients will be treated on a standard fractionation protocol with 40 fractions. This will allow 400 potential fractions to be auto-segmented in real time. Once Phase I is successfully completed we will aim to continue recruitment of a further 20 patients as Phase II. For this phase we will open recruitment to patients with lymph node positivity, hypofractionation (as per Department protocols) and intermittent imaging (imaging less frequently than every fraction).

Radiation: R/T gating kV intrafraction monitoring
This is a Phase I Pilot study to assess the feasibility of implementing prostate radiotherapy gating using kV intrafraction monitoring.




Primary Outcome Measures :
  1. Feasibility [ Time Frame: 2 years ]
    Technique will be determined as feasible if 90% of treatment fractions are successfully segmented in real time.


Secondary Outcome Measures :
  1. Time for procedure [ Time Frame: 2 years ]
    Measurement of time taken to perform KIM gating to guide future department resource questions.
