title: Needle imaging during ultrasound-guided permanent prostate implants.
abstract: As demonstrated by water phantom experiments and clinical observations, the reverberation artifact associated with the ultrasound needle image during permanent prostate implants is extremely useful in determining precise radioactive seed positioning. It also serves as an independent quality assurance check of the number of seeds in the strand.
