Development Process and Detailed Introduction of PET Digital Technology
1. Development Process of PET Digital Technology In the initial PET systems, energy, position, and time information were converted into digital signals using photomultiplier tubes (PMT), front-end analog circuits, and subsequent analog-to-digital converters (ADC/TDC) for event matching and image reconstruction. Due to the relatively backward chip technology at that time, the analog-to-digital conversion unit could … Read more
