Background:

  • Low dose rate (LDR) prostate brachytherapy is a common treatment for localized prostate cancer.
  • Accurate seed placement is critical for effective dose delivery and minimizing side effects.
  • Current methods can be limited by manual precision and real-time imaging integration.

Purpose of the Study:

  • To present a fully automated robotic system for MRI-guided LDR prostate brachytherapy.
  • To introduce a novel MR-compatible seed injector and image-registration marker.
  • To evaluate the system's accuracy and precision in seed deployment and needle targeting.

Main Methods:

  • Development and integration of the MrBot robotic system with an automated MR-compatible seed injector.
