A new development in ultrasound-compatible gynecologic brachytherapy simulators

Area of Science:

• Medical simulation
• Gynecologic oncology
• Radiation oncology

Background:

• Gynecologic brachytherapy is crucial for cervical cancer treatment.
• Declining utilization necessitates improved resident training methods.
• Existing simulators lack procedural fidelity.

Purpose of the Study:

• To develop a high-fidelity, multi-imaging compatible gynecologic brachytherapy training simulator.
• To address the limitations of current training models.

Main Methods:

• A custom simulator was developed based on an existing pelvic ultrasound trainer.
• Incorporated features: cervical os, endometrial canal, and a palpable hypoechoic tumor.
• Utilized materials with water-equivalent properties for ultrasound, CT, and MRI compatibility.

Main Results:

• The simulator was developed within 3 months.
• The model demonstrated durability with multiple tandem insertions.
• Material properties were suitable for ultrasound, CT, and MRI.

Conclusions:

• A high-fidelity, ultrasound-compatible simulator was successfully developed for gynecologic brachytherapy training.
• Improved resident training can enhance procedural skills and potentially patient survival.
• Future enhancements include interstitial training capabilities and anatomical variations.
