A new device to stabilize templates for transperineal I-125 implants

Area of Science:

• Oncology
• Medical Physics
• Surgical Technology

Background:

• Transperineal Iodine-125 implantation is a key treatment for prostate cancer.
• Accurate seed placement is crucial for effective treatment and minimizing side effects.
• Current methods rely on CT-based planning and transrectal ultrasound (TRUS) for verification.

Purpose of the Study:

• To introduce and describe the design of a novel adjustable device, the WIPI.
• To highlight the WIPI's role in stabilizing the perineal template and rectal obturator.
• To demonstrate the WIPI's utility during the planning and implantation phases of prostate brachytherapy.

Main Methods:

• Development of an adjustable device (WIPI) for procedural stabilization.
• Assessment of WIPI compatibility with CT scanning and transrectal ultrasound.
• Evaluation of WIPI integration with the Mick applicator for precise needle placement.

Main Results:

• The WIPI device provides stability for the perineal template and rectal obturator.
• The device is compatible with essential imaging and delivery technologies (CT, TRUS, Mick applicator).
• The WIPI is designed for ease of use during transperineal prostate implant procedures.

Conclusions:

• The WIPI device offers a simple and effective solution for stabilizing components during prostate brachytherapy.
• Its compatibility ensures seamless integration into existing clinical workflows.
• The WIPI has the potential to improve the accuracy and efficiency of transperineal Iodine-125 prostate implants.
