Brief summary

This study will look at how feasible it is to use a certain type of Computed Tomography (CT) to scan prostate cancer, called a high quality volume CT scan. It is hoped that this technique will help doctors provide a higher-quality image of the prostate cancer, making it easier to plan the area that will be treated. Using this type of CT scan will also lessen the amount of time patients spend in the scanner. This study will not offer patients a different treatment for their prostate cancer. Patients will receive the most appropriate standard treatment whether or not they are in this study.

Interventions

OTHERHigh Quality Volume CT Scan; MRI Scan

Patients will have the High Quality volume CT scan immediately after their CT scan followed by MRI scan. \--------------------------------------------------------------------------------

Design outcomes

Primary

Measure	Time frame
Using different scanning methods for patients undergoing radical external beam radiotherapy for prostate cancer to determine inter-observer variability in prostate gland delineation on the images.	6 months

Secondary

Measure	Time frame
Determine the concordance between delineators in identifying the prostate apex on the 2 CT image sets. MRI will be considered the gold-standard for identifying the prostate apex.	6 months
