Charge Sharing Compensation Using Coincidences for X-Ray Photon Counting Detectors (UCLA Case No. 2019-543)

Summary: UCLA researchers in the Department of Radiological Sciences have developed a novel method for coincidence counting to reduce the noise inherent in photon counting detectors. Background: The computed tomography (CT) scanning market is projected to grow from ~$6 billion to over $10 billion in 2030. Approximately 10% of this market size is...
