Title: The Innovations of William L. Rogers

Introduction

William L. Rogers is a notable inventor based in Ann Arbor, MI (US). He has made significant contributions to the field of imaging technology, holding a total of 3 patents. His work primarily focuses on advanced photon detection and gamma ray imaging, which have important applications in medical imaging and diagnostics.

Latest Patents

One of his latest patents is for a high-resolution photon detector. This apparatus is designed to identify the location of a photon source within an imaging area. It generates photons with energies within a known energy range. The apparatus includes two oppositely facing cameras, each equipped with a first detector unit that causes scattering when a photon enters. This unit generates signals indicative of the scattering event's location, energy, and time. The second detector unit absorbs the scattered photon and generates signals indicative of the absorption event's energy and time. The generated signals are mathematically combined to determine the source's location.

Another significant invention is a Compton camera. This device includes a first detector unit anatomically configured to mirror the external surface of a portion of a patient, including an object to be imaged. A second detector unit is positioned outside the imaging area to receive scattered photons from the first unit.

Additionally, he has developed a gamma ray imaging detector with three-dimensional event positioning. This detector is designed for nuclear medical imaging and includes an array of photodiode detectors on opposite surfaces of a scintillating crystal. By measuring the relative distribution of detection signal intensities produced by each photodiode, it is possible to measure the depth of interaction of a gamma ray absorption event along the Z-axis direction of the crystal, as well as its spatial position in the X-Y plane and its absorption energy. The measured depth of interaction is used to refine the calculation of spatial location and improve the performance characteristics of the imaging detector.
