Title: Innovations in Ultrasonic Imaging by Qifeng Wei

Introduction

Qifeng Wei is a notable inventor based in Wayland, MA (US), recognized for his contributions to the field of ultrasonic diagnostic imaging. With a total of five patents to his name, Wei has made significant advancements in the analysis of mitral regurgitation, a critical area in cardiovascular diagnostics.

Latest Patents

Wei's latest patents include groundbreaking technologies that enhance the understanding and quantification of mitral regurgitation. One of his patents describes an ultrasonic diagnostic imaging system that quantifies regurgitant flow through a mitral valve. This system utilizes a flow quantification processor to create a mathematical model of the flow velocity field proximal to a regurgitant orifice. The model produces velocity vectors directed toward the orifice, which are adjusted for ultrasound physics to yield expected velocity values. These values are then compared with actual Doppler velocities, allowing for precise calculations of the true orifice location, flow rate, and volume flow.

Another significant patent focuses on an ultrasonic color flow map for analyzing mitral regurgitation. This system employs color-flow imaging to assess regurgitant flow by producing Doppler velocity measurements around a regurgitant valve. The measurements are used to create a color-coded image that distinctly identifies an iso-velocity surface, enhancing the accuracy of regurgitant flow quantification.
