Title: Wanwen Chen and Needle-Tracking Innovation.

Introduction

Wanwen Chen is an inventor associated with Carnegie Mellon University in Pittsburgh, Pennsylvania. His patent work addresses the challenge of tracking a curved needle as it is inserted into a subject, an important task in image-guided procedures.

Latest Patents

Chen is associated with 1 patent, titled “System and Method for Tracking a Curved Needle.” The invention describes a system, method, and computer program product that track a needle across a sequence of images. The method first assesses the needle’s visibility. When visibility meets a specified threshold, it detects the needle’s location using an algorithm that accounts for the needle’s curvature. When visibility falls below the threshold, it uses a different algorithm to detect the location. It then tracks the needle through the image sequence using the locations identified by both approaches.

Career Highlights

The patent highlights Chen’s work on image-based needle tracking. By adapting its detection approach to the needle’s visibility, the system is designed to maintain tracking across changing image conditions.
