Title: Innovations of James A. Smith in Ultrasound Imaging
Introduction
James A. Smith is a notable inventor based in Pewaukee, WI (US), recognized for his contributions to ultrasound imaging technology. With a total of 3 patents, Smith has made significant advancements that enhance the quality and efficiency of ultrasound imaging systems.
Latest Patents
Smith's latest patents include a "Frame Interpolator for Increasing Apparent Acoustic Frame Rate" and a "Color Adaptive Frame Averaging" method. The frame interpolator patent describes a method and apparatus for increasing the apparent acoustic frame rate of ultrasound images. This innovation involves acquiring frames of acoustic data at the acoustic frame rate, storing them in double-buffered acoustic frame buffers, and scan converting them sequentially. By utilizing a frame delay buffer, the scan converter can always read from a complete frame of acoustic data, effectively eliminating swirl artifacts. The scan-converted acoustic data is then processed through a frame interpolator that incorporates a two-point FIR filter, allowing for the generation of unique frames of interpolated data.
The color adaptive frame averaging method enhances ultrasound images by adding persistence. This is achieved by computing filter weighting coefficients to compensate for aliased color data, with frame rate compensation being adjusted through these coefficients. The method employs an infinite impulse response filter to achieve its objectives.
