Development and Characterization of an Endoscopic TOF PET System

The endoscopic time-of-flight (TOF) positron emission tomography (PET) concept has many advantages compared with the traditional PET system. It improves the image quality by delivering higher spatial resolution and enhancing the signal-to-noise ratio. Implementing the endoscopic TOF PET system in an ultrasonic probe requires an ultra...

Implementation, Characterization, and Optimization of an FPGA-based Time-to-Digital Converter

Many fields need high performance time measurements, including Single-Photon Avalanche Diode (SPAD) cameras, Positron Emission Tomography (PET) systems, and other time-of-flight systems. These measurements are often performed by means of time-to-digital converters, that for these applications, require high resolution, accuracy, and throughput....
