We develop 3D integrated Photon-to-Digital Converters (PDC) for photon counting applications needing sub-nanosecond timing resolution. Our goal is to provide a detector capable of delivering single photon timing resolution below 50 ps that could enable Time-of-Flight positron emission tomography (ToF-PET) and computed tomography (ToF-CT). We will review the benefits and the challenges posed by...
Introduction: Edema, an abnormal increase in tissue water fraction (WF), affects over one million Canadians chronically. Cerebral edema (CE) is especially concerning, as it is a predictor of mortality in stroke and traumatic brain injury. While magnetic resonance imaging and computed tomography can assess WF, they are costly, not readily available, and inappropriate for continuous...
Introduction: Magnetic Resonance Imaging (MRI) is a powerful diagnostic tool that provides detailed images of soft tissues, making it essential for a wide range of medical applications. However, conventional MRI systems rely on high-field (1.5 – 3.0 Tesla [1, 2]) superconducting magnets, resulting in high cost [3, 4], significant infrastructure requirements, and limited accessibility in many...
Introduction: Magnetization Transfer (MT) is a Magnetic Resonance Imaging (MRI) contrast enhancement technique that exploits the exchange of magnetization between pools of free-water protons and protons bound to macromolecules in tissue [1]. Chemical Exchange Saturation Transfer (CEST) MRI is a direct application of MT, which can noninvasively image dilute CEST agents (including amide...
