PET quality control model
Follow the recommended design of IEC and NEMA organizations to meet the requirements of GB/T 18988.1 and the Ministry of health's positron emission tomography (PET) quality control testing specification.
PET spatial resolution motif conforms to the relevant provisions of NEMA NU2-2001 third and test specification 4.1.
★It is a capillary glass tube with a diameter of 1mm and a diameter of 1.8mm
★It includes a point source adapter to facilitate users to measure and locate.
The PET scattering module conforms to the relevant provisions of NEMA NU2-2001 fourth and test specification 4.3.
★Positron emission tomography X (PET scanner) quality control with line source tube cylindrical body;
★The scatter fraction and counting loss and random coincidence rate of PET scanner were measured; counting loss and random coincidence accuracy were corrected.
★A polyethylene cylinder with a line source in eccentric position is included.
★The length of the cylinder is 700mm, the outer diameter is 200mm, the outer diameter of the line source is about 5mm, and the length is about 800mm.
The PET sensitivity module meets the relevant requirements of NEMA NU2-2001 fifth and test specification 4.2.
★The PET positron detection capability and resolution are measured using a line source tubular sensitivity module.
★It contains 5 metal sleeves with different diameters and a line source. The metal tube is 700mm long and thick 2.5mm.
★The external diameters of the five metal tubes were 9.5, 12.7, 15.9, 19.1 and 22.2mm respectively.
★The outer diameter of the line source is about 5mm and the length is about 800mm. The inserted casing can be continuously measured under the condition of known absorption activity.
