PET-CT refers to positron emission tomography.
PET-CT integrates PET and CT in a perfect way, with PET providing detailed molecular information about the function and metabolism of the lesion and CT providing precise anatomical localization of the lesion, so that a single imaging session can obtain tomographic images of the entire body in all directions, which is sensitive, accurate, specific, and precise in localization. The newest and most advanced technology in the world is a new generation of medical devices.
Extended information:
CT fluoroscopy refers primarily to the continuous scanning of the same level. Instead, it refers to the rapid reconstruction and display of images. In order to be able to achieve the effect of displaying in real time as much as possible, a common method is to reduce the calculation matrix and use a 256*256 matrix instead of a 512*512 matrix. This allows for the display of 5 or more images per second, allowing for continuous and almost real-time monitoring of many interventions.
During a volumetric scan, the bulb detector system rotates in multiple consecutive revolutions while the patient moves continuously through the rack. A common scanning speed is 1 to 2 levels of collimation width per 360 degrees. This means that for a CT with a 1s scan time, single row of detectors, and a layer thickness of 1 to 10 mm, the scanning speed is 1 to 10 m/s.
For a multilayer scanning system and a CT with a subsecond rotation time, it is possible to dramatically increase the speed of bed entry. Scanning speeds can be increased up to 32 times faster by going from a 1s scan time single-layer scanning system to a 0.5s scan time 16-layer scanning system.
