2019 SEP 20 (NewsRx) -- By a News Reporter-Staff News Editor at Clinical Trials Daily -- Investigators publish new report on Robotics. According to news reporting originating from Baltimore, United States, by NewsRx correspondents, research stated, “We present a robot-assisted approach for transrectal ultrasound (TRUS) guided prostate biopsy. The robot is a hands-free probe manipulator thatmoves the probe with the same 4 DoF that are used manually.”

Funders for this research include National Cancer Institute, Patrick C. Walsh foundation.

Our news editors obtained a quote from the research from Johns Hopkins University, “Software was developed for three-dimensional (3-D) imaging, biopsy planning, robot control, and navigation. Methods to minimize the deformation of the prostate caused by the probe at 3-D imaging and needle targeting were developed to reduce biopsy targeting errors. We also present a prostate coordinate system (PCS). The PCS helps defining a systematic biopsy plan without the need for prostate segmentation. Comprehensive tests were performed, including two bench tests, one imaging test, two in vitro targeting tests, and an IRB-approved clinical trial on five patients. Preclinical tests showed that image-based needle targeting can be accomplished with accuracy on the order of 1 mm. Prostate biopsy can be accomplished with minimal TRUS pressure on the gland and submillimetric prostate deformations. All five clinical cases were successful with an average procedure time of 13 min and millimeter targeting accuracy. Hands-free TRUS operation, transrectal TRUS guided prostate biopsy with minimal prostate deformations, and the PCS-based biopsy plan are novel methods. Robot-assisted prostate biopsy is safe and feasible.”

According to the news editors, the research concluded: “Accurate needle targeting has the potential to increase the detection of clinically significant prostate cancer.”
