Method for computed tomography-ultrasound interactive prostate brachytherapy

摘要

The invention is a method for the treatment of cancer comprising interactive imaging techniques to optimize the placement of radioactive seeds in a portion of the body containing cancer. The method comprises the computer assisted development of a seed placement plan based on images obtained on a pre-operative day. Seeds are placed into the region of interest in the body, typically the prostate, using an ultrasound guided method. The seeds are imaged using computed tomography (CT) to assess the dose distribution. A second plan, or miniplan, is developed based on information obtained in the CT scan. Additional ultrasound-guided seeds are placed at the same procedure based on the miniplan to optimize the final dose coverage.
