Title: Innovations in Medical Imaging by Inventor Chung Chan

Introduction

Chung Chan is a prominent inventor based in Glenview, IL (US), known for his significant contributions to the field of medical imaging. With a total of 10 patents to his name, Chan has focused on enhancing the quality and performance of medical imaging systems through innovative technologies.

Latest Patents

One of Chan's latest patents is an "Apparatus and method for medical image reconstruction using deep learning to improve image quality in positron emission tomography (PET)." This invention utilizes a deep learning convolutional neural network (CNN) to reduce noise in PET images. The network is trained on a variety of noise levels to produce high-quality images, regardless of the input image's noise level. By slicing a three-dimensional PET image into two-dimensional slices and employing separate CNN networks for each plane, Chan's method averages the outputs to achieve uniform image quality. Additionally, feature-oriented training is implemented by segmenting training images into lesion and background regions, applying greater weights to the lesion region in the loss function.

Another notable patent is the "Neural network for improved performance of medical imaging systems." This invention addresses the restoration of low-quality images through reconstruction techniques. By simulating a real patient phantom in Monte Carlo simulations, Chan's neural network can differentiate between higher and lower performance systems. The trained network outputs images from lower performance systems with characteristics of higher performance systems, thereby enhancing the overall imaging quality.
