Iodine-125 (I-125) seeds offer a radiation-safe and cost-effective method for temporary interstitial implants. Customized seed arrangement in catheters optimizes dose distribution, outperforming standard Ir-192 ribbons.

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Nuclear Medicine

Background:

  • Iodine-125 (I-125) is utilized for temporary interstitial implants.
  • Radiation safety and cost-effectiveness favor I-125 over other radioisotopes.
  • Customized source loading enhances dose distribution in brachytherapy.

Purpose of the Study:

  • To evaluate the efficacy of customized Iodine-125 seed arrangement in temporary interstitial implants.
  • To compare dose distributions achieved with customized I-125 loading versus standard Ir-192 ribbons.
  • To highlight the radiation safety and cost benefits of using I-125 sources.

Main Methods:

  • Loading I-125 seeds into implant catheters for customized source arrangement.
  • Optimization of implant dose patterns through precise seed placement.
