Title: Innovator Spotlight: Jonathan Gang Li

Introduction

Jonathan Gang Li, a distinguished inventor based in Gainesville, FL, has made significant contributions to the field of optical tracking systems, especially in medical applications. With a remarkable portfolio of five patents, he is dedicated to enhancing the safety and effectiveness of radiotherapy treatments through innovative technologies.

Latest Patents

One of Jonathan's latest inventions is the "Ambiguity-Free Optical Tracking System." This sophisticated system includes a position sensor unit comprised of two cameras that track multiple infrared reflecting markers affixed to a patient's skin. The system employs an ambiguity elimination algorithm that identifies and removes ambiguous markers, ensuring accurate tracking during treatment. The use of a recursive backtracking algorithm allows the system to account for missing or misplaced markers, thereby preventing complications during medical procedures.

Another notable patent is the "Prevention of Setup Errors in Radiotherapy." This patient safety system utilizes optical tracking technology within a linear accelerator treatment room to avoid significant setup errors. It begins with a patient undergoing a computed tomography (CT) treatment-simulation scan, during which a CT ball bearing (BB) is placed on the patient's surface. Before treatment commences, this BB is replaced with an infrared reflective marker, and the system continuously compares its position against a predetermined reference. If deviations exceed a certain threshold, the system automatically halts radiation, ensuring patient safety.
