The system used a closed-bore 1.5-T MR imaging unit and enables one to take advantage of the higher signal-to-noise ratio achieved with traditional magnet designs, which is crucial for accurate targeting and monitoring of prostate interventions. In the first of the four canine studies, reliable needle placement, with all needles placed within 2 mm of the desired target site, was achieved. In two other studies, MR imaging was used to monitor distribution of injected contrast agent solution (gadopentetate dimeglumine mixed with trypan blue dye) in and around the prostate, thereby confirming that solution had been delivered to the desired tissue and also detecting faulty injections. In the final study, accurate placement and MR imaging of brachytherapy seeds in the prostate were demonstrated. The described system provides a flexible platform for a variety of minimally invasive MR image-guided therapeutic and diagnostic prostate interventions. {\textcopyright} RSNA, 2003.}, isbn = {0033-8419} } @inbook {1380, title = {Transrectal prostate biopsy inside closed MRI scanner with remote actuation, under real-time image guidance}, booktitle = {MEDICAL IMAGE COMPUTING AND COMPUTER-ASSISTED INTERVENTION-MICCAI 2002, PT 1}, year = {2002}, note = {UT: 000189412100012BE: Dohi, T: Kikinis, R 5th International Conference on Medical Image Computing and : Computer-Assisted Intervention SEP 25-28, 2002 TOKYO, JAPAN Z9: 26 WC: Computer Science, Theory \& Methods Hi{\'a}nyz{\'o} Besorol{\'a}s: {\textquoteright}Article; Proceedings Paper{\textquoteright},25,0 $\#$K{\"o}nyv Kiad{\'a}s helye ismeretlen }, month = {2002}, pages = {91 - 98}, publisher = {Springer Verlag}, organization = {Springer Verlag}, address = {Tokyo}, abstract = {We present the proof-of-concept prototype of a prostate biopsyrobot to be used inside a conventional high-field MRI scanner. A three degree-of-freedom (DOF) mechanical device translates and rotates inside the rectum and enters a needle into the body, and steers the needle to a target point pre-selected by the user. The device is guided by real-time images from the scanner. Networked computers process the medical images and enable the clinician to control the motion of the mechanical device that is operated remotely from outside the imager. The system is also applicable to localized prostate therapy and also demonstrates potential in other intra-cavitary procedures. } }
