Brief Summary:
Cancers are often treated with external beam radiotherapy. Current radiotherapy treatments are performed using computed tomography (also known as CT) scans which may not always clearly identify the cancer. In some instances, magnetic resonance imaging (MRI) may be able to better identify cancers. Therefore, efforts are currently underway to use the MRI scans to improve radiotherapy treatments or eventually even use radiotherapy equipment that only uses MRI scans to guide treatments. This new technology that will only use MRI scans to guide treatments is called the Linac-MR (linear accelerator with an MRI). The purpose of this pilot phase of the study is to test whether the Alberta linac-MR P3 system at the Cross Cancer Institute can acquire high quality MR images safely. It will allow the researchers to develop the best collection of MR images possible with this new machine, in order to allow them to visualize tumors for future patients that are treated on this machine.

Condition or disease Intervention/treatment Phase
Cancer Device: MR scan with the Alberta linac-MR P3 system Not Applicable

Detailed Description:
This prospective, pilot phase, clinical trial is an imaging study to optimize the necessary MR sequences on the Alberta linac-MR P3 system to allow for MR-guided radiotherapy in adult patients with cancer that are treated with high dose external beam radiotherapy. Each participant will undergo a single MR imaging session (30 - 40 minutes) on the Alberta linac-MR P3 system. Towards the end of the study, patients will be approached to participate in an optional sub-study, where they will undergo a total of five MR imaging sessions (performed every two to five days) to allow for an assessment of inter-fraction motion.

Arm Intervention/treatment
Experimental: MR Imaging on the Alberta linac-MR P3 system
All participants will undergo a single MR imaging session (30-40 minutes) on the Alberta linac-MR P3 system.
Device: MR scan with the Alberta linac-MR P3 system
Single MR imaging session to develop and optimize the necessary MR sequences on the Alberta linac-MR P3 system to allow for MR-guided radiotherapy.

Primary Outcome Measures :
  1. Number of high-quality MR image data sets acquired for each major tumour site (prostate, liver, lung, CNS, and breast) [ Time Frame: Through study completion, approximately 1 year ]
    Clinical radiologists, medical physicists, and radiation oncologists will work together to develop MR sequences that can delineate tumour target volumes on the Alberta linac-MR P3 system. Over the course of the trial, the clinical radiologists will work with medical physicists to optimize these sequences to allow for the development of optimal MR images, with the goal to develop of series of protocols that can be utilized to provide clear MR image guidance for each tumour group.

Secondary Outcome Measures :
  1. Quantify the patient experience on the Linac-MR [ Time Frame: After the first and last scan, up to 5 weeks ]
    Participants will complete a questionnaire at the end of their first scan regarding their experience having imaging done on the Linac-MR. Participants taking part in the optional sub-study will complete the same questionnaire at the end of their last set of imaging.
