Claim 2:
3. The multi-physical field imaging system based on PET-CT and DAS according to claim 2, wherein the imaging system comprises:
a PET machine, configured to scan electrons released by tracers in the non-metallic sample to be tested to obtain internal images of the non-metallic sample to be tested;
a CT machine, configured for obtaining CT images of the non-metallic sample to be tested;
a distributed acoustic sensing and monitoring system, connected to the distributed acoustic sensors and configured for analyzing obtained acoustic emission monitoring data, picking up data variation points for acoustic emission locating, obtaining spatiotemporal information of the acoustic emission events, and imaging the internal structure of the non-metallic sample to be tested;
the pressure device, configured for accommodating the non-metallic sample to be tested and applying pressure to the non-metallic sample to be tested;
an electric metering pump configured for applying confining pressure, an electric metering pump configured for applying axial pressure, and an electric metering pump configured for providing tracer; and
a pressure loading control system, connected to the electric metering pump configured for applying confining pressure, the electric metering pump configured for applying axial pressure, and the electric metering pump configured for providing tracer.
