Robot-assisted brachytherapy for treating prostate cancer

September 07, 2017

Dr. Yu led a team of medical physicists, engineers, radiation oncologists, radiologists and urologists who spent seven years developing the robotic system, which is called EUCLIDIAN. It incorporates high resolution ultrasound image processing, dose planning using genetic algorithms, 3D visualization, smart needle rotation for reducing tissue deformation and prostate displacement, and force feedback from nano-sensors installed at various points on the robot. Needle insertion and seed delivery are fully automatic.

"The robot is controlled by a physician via a handheld controller and a computer interface," he says. "It is capable of reverting to manual needle and seed insertion any time the physician desires."

Dr. Yu says the robot has been described in 30 scientific papers by the Jefferson team, and the intraoperative software that operates the robot has been under development for more than 15 years and has been reported in 20 scientific papers.

"Robotic brachytherapy combines the expertise of a multi-disciplinary clinical team led by radiation oncologists, with the most sophisticated robot technologies available today, to aim for the ultimate goal of delivering the best possible dose distribution each time for every patient, and verifying this before the patient leaves the procedure," said Dr. Dicker, who is the principal investigator of the EUCLIDIAN clinical trial at Jefferson.
