Title: Innovations by James K. Riley in Ultrasound Imaging

Introduction

James K. Riley is a notable inventor based in Shingle Springs, California. He has made significant contributions to the field of ultrasound imaging, holding a total of 5 patents. His work focuses on enhancing the capabilities of ultrasound technology, which is crucial in medical diagnostics.

Latest Patents

One of his latest patents is titled "Method and means for steering phased array scanner in ultrasound imaging." This invention involves a phased array of transducer elements that can be selectively directed by grouping adjacent transducer elements. The electrical signals in each group are mixed with a modulation signal of a fixed frequency, which is phased delayed based on the angle of direction of a reflection point in the imaged volume. The mixed electrical signals are then summed and timed delayed to form an image beam.

Another significant patent is the "Adaptive time gain compensation system for ultrasound imaging." This gain control system utilizes a histogram analyzer to identify image pixel populations related to various tissues and artifacts. The histogram analyzer establishes mean peak values and identifies nulls between image populations to set gain versus depth break points. A comparator uses a threshold level to compare image information corresponding to soft tissue, and a TGC generator generates a time gain control signal based on preselected parameters.
