简要总结
RATIONALE: New imaging procedures such as CT-on-rails™ may improve the ability to pinpoint the location of the tumor and decrease radiation therapy damage to healthy tissue.
PURPOSE: This phase I/II trial is studying how well computed tomography (CT) scans using CT-on-rails™ work in pinpointing the location of the tumor in patients with prostate cancer.
详细描述
OBJECTIVES:
Primary
- Validate the software for CT-on-rails™ by comparing prostate target localization via daily ultrasound vs computed tomography (CT) in patients undergoing radiotherapy for prostate cancer.
Secondary
- Determine the potential benefit of using fiducials in the prostate of patients undergoing daily CT scans and/or ultrasounds for localization.
- Determine the intra- and inter-radiation treatment setup and target position uncertainties, in terms of isocenter coordinates in space, using both the ultrasound and CT scans compared to the coordinates of the isocenter determined at simulation, in these patients.
