title: A virtual fluoroscopy system to verify seed positioning accuracy during prostate permanent seed implants.
abstract: OBJECTIVE
  The purpose of this project was to develop a software platform to produce a virtual fluoroscopic image as an aid for permanent prostate seed implants.
  
  
  METHODS
  Seed location information from a pre-plan was extracted and used as input to in-house developed software to produce a virtual fluoroscopic image. In order to account for differences in patient positioning on the day of treatment, the user was given the ability to make changes to the virtual image.
  
  
  RESULTS
  The system has been shown to work as expected for all test cases.
  
  
  CONCLUSIONS
  The system allows for quick (on average less than 10 sec) generation of a virtual fluoroscopic image of the planned seed pattern. The image can be used as a verification tool to aid the physician in evaluating how close the implant is to the planned distribution throughout the procedure and enable remedial action should a large deviation be observed.
