Title: Glenn F. Knoll: Innovator in Gamma Ray Imaging Technology

Introduction

Glenn F. Knoll is a prominent inventor based in Ann Arbor, MI (US), known for his significant contributions to the field of nuclear medical imaging. With a total of 8 patents to his name, Knoll has made remarkable advancements in gamma ray imaging technology, enhancing the capabilities of medical diagnostics.

Latest Patents

Among his latest patents is the "Gamma ray imaging detector with three-dimensional event positioning." This innovative device is designed for nuclear medical imaging and features an array of photodiode detectors positioned on opposite surfaces of a scintillating crystal. By analyzing the relative distribution of detection signal intensities from each photodiode, the device can accurately measure the depth of interaction of a gamma ray absorption event along the Z-axis, as well as its spatial position in the X-Y plane and absorption energy. This depth measurement is crucial for refining spatial location calculations and improving the imaging detector's performance characteristics.

Another notable patent is the "Gamma ray imaging detector," which is also intended for nuclear medicine applications. This detector utilizes a single scintillation detector crystal that converts absorbed gamma rays into multiple scintillation photons. The crystal emits scintillation light primarily at wavelengths longer than 475 nanometers and is preferably made of thallium-doped cesium iodide. An array of photodiodes is arranged along one side of the crystal to capture the scintillation photons, generating an electrical output signal proportional to the number of photons received. The use of low-capacitance and low-noise diodes, such as silicon drift photodiodes, ensures that the generated signal is easily detectable above the electrical noise.
