Title: Dave Hedberg and Ultrasound Imaging Innovation.

Introduction

Dave Hedberg is an inventor associated with Menlo Park, California, and Acuson Corporation. His patent work addresses ultrasound imaging, with a focus on improving the clarity and diagnostic value of real-time B-mode and M-mode displays.

Latest Patents

Hedberg is credited with 1 patent: “Ultrasound Imaging Method and Apparatus with Dynamic Non-Linear Filtering.” The invention describes methods and apparatus that process ultrasound signals using programmable, dynamically variable nonlinear filters. These filters can adjust their responses automatically, operate along individual scan lines or across multiple lines, and use local signal measurements and image position to guide processing. The processed signals are then scan-converted and displayed, with programmable settings that can accommodate different imaging applications.

Career Highlights

Hedberg’s listed patent reflects work on signal-processing techniques for medical ultrasound systems. The approach combines flexible filtering with image acquisition and display to support clearer ultrasound images and potentially more useful diagnostic information.

Collaborations

The patent lists Michael J. Tierney and Ismayil M. Guracar among Hedberg’s coworkers. The invention is associated with Acuson Corporation.

Conclusion

Dave Hedberg’s patent documents a contribution to ultrasound imaging through dynamically controlled nonlinear filtering designed to enhance real-time image clarity and diagnostic information.
