Summary
Brief summary (as posted)
The purpose of this study is to evaluate the effectiveness of using ultrasound to image and track pancreas/duodenum motion during radiation therapy treatment delivery. Also develop a workflow and process to allow the final ultrasound system to be used routinely by radiation therapists.

Design
Arms and outcomes
Arms (1)
- label
- Pancreas cancer
- description
- Develope a stand, cradle or robotic arm to hold the ultrasound probe, to obtain an ultrasound just before a standard radiation therapy treatment is given.
- interventionNames
- Device: Ultrasound
Primary outcomes (1)
- measure
- Evaluate the use of ultrasound to detect motion of pancrease and surrounding structures
- timeFrame
- 5 years from the date of enrollment
- description
- Design and construct stands to hold the ultrasound probe. Issues to be considered in the design include (i) avoiding the stand and probe blocking radiation beams, (ii) avoiding ultrasound going through the ribs, (iii) minimizing the effect of respiration motion. Explore building the probe into the immobilization device (e.g., Alpha cradle) or using robotic arm.
Secondary outcomes (1)
- measure
- Quality of ultrasound imaging for Pancreas
