A. 3. Spatial resolution detection point source bracket

The nuclide used for spatial resolution detection is 18F, and its specific activity is recommended by the manufacturer.

The test source is a high specific activity radioactive point source placed inside a capillary glass tube, with a line diameter of less than 1 mm in any direction. The point source is arranged in the following six positions:

a) Parallel PET longitudinal axis at 1/2 of the center of the field of view and 1 cm at the center of the cross-section;

b) Parallel PET longitudinal axis at 1/2 of the center of the field of view and 10 cm at the center of the cross-section;

c) Parallel PET longitudinal axis at 1/2 of the center of the field of view and at 20 cm of the cross-sectional center;

d) Parallel PET axial field of view, 3/8 from the center and 1 cm from the cross-sectional center;

e) Parallel PET axial field of view, 3/8 from the center and 10 cm from the cross-sectional center;

F) Parallel PET long axis axial field of view, 3/8 from the center and 20 cm from the cross-sectional center.
