Brief Summary

The purpose of this study is to evaluate the use of ionizing-radiation photo acoustic imaging (iRAI) for proton radiation treatment.

Conditions

Prostate Cancer

Outcome Measures

Primary Outcomes (1)

• Proton treatment dose overlay between predicted values and iRAI in CT images at the center plane of a tumor to achieve

  95% confidence interval in the gamma passing rate higher than 90% using 5%/5 mm criteria

  Approximately 36 months for trial accrual

Secondary Outcomes (1)

• Reliability of range discrepancies between predicted values and iRAI during 3-day treatments at the proximal, center, and distal plane of a tumor to achieve

  Approximately 36 months for trial accrual

Study Arms (1)

iRAI data collection

EXPERIMENTAL

Radiation therapists will position the participant on the treatment table. After the participant is setup, a water bag will be placed on his abdomen and a 2D transducer is placed on top of the water bag. The 2D transducer is held in place by an articulated arm attached to the treatment table. The water bag serves as a path for the photo acoustic waves created during treatment to be detected by the 2D transducer and captured for data collection.

Device: iRAI

Interventions

iRAI DEVICE

Ionizing-radiation photo acoustic imaging (iRAI) is a method of collecting images from inside the body using acoustic (sound) waves. Researchers will collect iRAI during a participant's radiation treatments. Researchers will use this imaging to examine the delivery and dose of the radiation to the participant's prostate. Researchers will also compare the delivery and dose calculated from iRAI to the expected doses that were calculated from CT images which are done as standard of care.

iRAI data collection

Eligibility Criteria

• Age: 18 Years - 100 Years
• Sex: male
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Disease: Prostate cancer
• Treatment site:
• Prostate or prostate and seminal vesicle
• No regional lymph node is involved
• Patient's body weight: Patient's body weight is less than 350 lbs to consider the total weight limit that the ProteusONE treatment table and the robotic arm can operate
• Treatment volume size: maximum size less than 15 x 15 cm in a cross-section and a thickness less than 20 cm to consider 2D transducer matrix size
• Provision to sign the consent form and understand the non-invasiveness of iRAI
• Patient agreement on tolerance on placing a water bag to acquire iRAI during treatment
• Treatment modality: Proton radiation therapy with UFHPTI's ProteusONE gantry using PBS

You may not qualify if:

• A patient who would not be tolerable or will feel nervous about being touched on the skin with a water bag
• A patient with a significant medical implant or hardware in the treatment area
