Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-A new study on robotics is now availab le. According to news reporting out of Incheon, South Korea, by NewsRx editors, research stated, "The latest advancement in high-intensity focused ultrasound (H IFU) treatment technology integrates magnetic resonance imaging (MRI) guidance f or precise treatment of prostate disease." The news journalists obtained a quote from the research from Gachon University G il Medical Center: "As conventional electromagnetic motors are not applicable fo r utilization within MRI scanners, we have developed a prototype robotic system driven by pneumatic stepper motors to control the movement of the HIFU transduce r within an intrarectal probe during MRI-guided HIFU treatment procedures. These pneumatic stepper motors were constructed entirely from MRI-compatible plastic materials. Assessment of the robotic system's MRI compatibility was conducted ut ilizing a 3.0T MRI scanner, revealing no discernible MRI image distortion with a minor decrease in the signal-to-noise ratio (2.8%) during the moto r operation. The robotic system enabled the transducer to move inside the probe with two degrees of freedom, allowing both linear and rotational motion. The pos itional accuracy of the transducer movement was assessed, yielding ±0.20 and ±0. 22 mm accuracies in the forward and backward linear movements, respectively, and ±0.79° and ±0.74° accuracies in the clockwise and counterclockwise rotational m otions, respectively."
