- Prostate brachytherapy procedure is operator experience dependent that requires training to ensure high quality outcomes
- There is presently inadequate training opportunities for the TRUS-based brachytherapy procedure during radiation oncology residency programs
- The use of prostate brachytherapy has continued to decline, which results in a substantial reduction in training opportunities
Goal:
To develop an in-house gelatin-based prostate phantom for training purposes during ultrasound-based prostate brachytherapy procedures
Ultrasound images of the phantom before and after needles insertion
Left to right: Survey results, Young's modulus vs. gelatin concentration, and CNR as a function of scattering agent concentration, respectively
- We have developed a 3D printing prostate phantom to be used for training purposes during interstitial prostate brachytherapy
- Based on the results, the reconstructed phantom could be used as an anthropomorphic surrogates for ultrasound imaging during brachytherapy procedures
