Keywords:  trus, ultrasound, probe, rectum, biopsy
introduction of a tiny transducer into the rectum to visualize the prostate gland with high frequency sound waves.
An ultrasound guidance tool utilizing sound waves for viewing the prostate for scans (pictures) and for viewing the placement of the seeds during the seeding procedure.
The ultrasound picture is taken by an ultrasound "probe'' that is inserted into the rectum, which is right next to the prostate gland. The probe transmits pictures of the prostate onto a screen, just like watching the prostate on a TV.
