A new software platform generates virtual fluoroscopic images for prostate seed implants, aiding physicians in real-time procedure verification and adjustment. This tool ensures accurate seed placement during treatment.

Area of Science:

Medical Imaging
Radiation Oncology
Software Development

Background:

Permanent prostate seed implants are a common treatment for localized prostate cancer.
Accurate seed placement is crucial for effective treatment and minimizing side effects.
Real-time intraoperative guidance can improve implant accuracy.

Purpose of the Study:

To develop a software platform for generating virtual fluoroscopic images.
To provide an aid for permanent prostate seed implants.
To enhance intraoperative decision-making during the procedure.

Main Methods:

Utilized pre-plan seed location data as input.
Developed in-house software to create virtual fluoroscopic images.
Incorporated user-adjustable features to account for patient positioning variations.
