4 Overview
The digitization mentioned in this document can be described as the conversion of continuous analog quantities into
Process of discrete digital quantities. Digital PET can be described as the energy information, time information and position information of a single event before coincidence.
All information is stored and processed in digitally coded PET.
PET digitization technology is based on digital signal processing hardware as a means to achieve accurate sampling of scintillation pulses.
a series of technologies. It may bring lower power consumption, more stable and superior performance, stronger scalability and adaptability.
PET digital technology is embodied in the process of signal sampling, which can convert the original analog signal into digital signal and output it. According to
The stage of converting the original analog signal into a digital signal in the sample circuit, the digitization of the PET signal is divided into the following two symbolic links. the electrical signal
Generation link (direct digitization after photoelectric conversion), single-event signal transmission link (before event coincidence). PET signal digitization technical requirements to
Meet at least one of the following.
a) Digitalization of single-event signal transmission
After the electrical pulse after photoelectric conversion is processed by analog circuit, the information of single event (position, time, energy, etc.)
Convert to digital signal and output.
b) Digitalization of electrical signal generation
The signal output by the photoelectric conversion device is directly digitized without analog signal processing. There are 4 technical solutions as follows.
---Directly digitize the electric pulse output by the analog optoelectronic device, and obtain the position, time and energy information of a single event;
---Digital sampling of the electrical pulse output by the analog optoelectronic device to obtain the original pulse waveform of a single event;
---Digital optoelectronic devices directly output digital single-event position, time, and energy information;
---Use digital optoelectronic devices to obtain digitized single-event original pulse waveform.
