Title: Shigao Chen: Innovator in Ultrasound Technology
Introduction
Shigao Chen, based in Rochester, MN, is a prominent inventor with a remarkable portfolio of 29 patents. His contributions predominantly focus on advancements in ultrasound technology, particularly in the area of attenuation coefficient estimation, which holds significant implications for medical imaging.
Latest Patents
Chen's latest innovations include two notable patents related to ultrasound attenuation coefficient estimation. The first patent details 'ACE' techniques designed to address frequency power ratio curve oscillations arising from signal interferences and non-uniform tissue structures. By smoothing the frequency power ratio curves, these techniques facilitate more accurate ACE calculations and lead to reduced sizes of regions of interest for linear regression.
The second patent presents further improvements in ultrasound attenuation coefficient estimation methods, where noise suppression is emphasized. This is achieved by using signal-to-noise ratio (SNR) as a quality control metric to restrict depth ranges for ACE adaptively. Additionally, through elevation focusing normalization, errors related to diffraction effects during the estimation process can be mitigated. Various methods of noise suppression in ACE techniques are also introduced, including techniques based on noise fields and singular value decomposition (SVD) filtering.
