Title: Leshan Sun: Innovator in Proton Beam Therapy
Introduction
Leshan Sun is a prominent inventor based in Irvine, CA, known for his contributions to the field of medical imaging and radiation therapy. With a focus on enhancing the precision of cancer treatment, he has developed innovative techniques that significantly improve patient outcomes. His work has led to the filing of two patents, showcasing his commitment to advancing medical technology.
Latest Patents
Leshan Sun's latest patents include groundbreaking techniques for detecting in real-time proton beam therapy. These techniques involve retrieving conversion data to convert proton dose to acoustic pressure based on medical imagery. The process utilizes 3D medical imagery of a region of interest (ROI) within a subject. A real-time signal indicates ultrasound pressure at a 2D ultrasound array positioned outside and in contact with the subject. The real-time 3D dose delivered in the ROI is determined by inputting the real-time signal into a dose detection module that incorporates a neural network trained on multiple instances of a training set.
Another significant patent is the development of an absolute in vivo radiation dosimetry tool with X-ray-induced acoustic computed tomography (XACT). This system enhances the precision of radiotherapy by measuring the absolute dose delivered to tumors and surrounding normal tissue during treatment. The imaging reconstruction system utilizes a model-based reconstruction method to provide accurate in vivo dose information, which is crucial for personalized cancer treatment.
