This study is designed to investigate whether daily images of the pelvis and bladder using a device called a cone beam CT scanner will help to increase the accuracy of radiotherapy treatment. The cone beam CT scanner is a part of the radiotherapy treatment unit. The results of the study may allow patients in the future who are undergoing radiotherapy treatment for bladder cancer to 1) have more accurately directed treatment, 2) have higher doses of radiation delivered to the tumour while keeping doses to the surrounding normal tissues as low as possible. This may allow eradication of the cancer while minimizing side effects of treatment.
This study consists of two phases: Phase A and Phase B. In Phase A, images were collected and analyzed and it was confirmed that it was useful to use the cone beam machine for daily Cone Beam CT Bladder (Phase B)treatment adjustments. In phase B, we hope to be able to use cone beam CT scans to more accurately direct the radiotherapy treatments on a daily basis.

Using cone beam CT scanner will help to increase the accuracy of your radiotherapy treatment. The cone beam CT scanner is a part of the radiotherapy treatment unit.
- To evaluate the feasibility of cone beam CT for daily on-line image guidance in patients receiving radiation therapy for bladder cancer. [ Time Frame: 5 years ]
- Measure interfraction,intrafraction & deformity of bladder;determine adequacy of present margins; report bladder volume changes during treatment; evaluate use of fiducial markers plus CBCT for on-line image guidance & transabdominal ultrasound system. [ Time Frame: 5 years ]
