How would you calculate the spatial resolution of a multiple
ring detector at the center of the FOV in the following
4mm wide discrete detectors separated by 1000 mm, using F18; assuming the root mean square (rms) range for F18 is about 0.2 mm and the block effect is considered to be negligible.
The spatial resolution at the center of 4 mm wide discrete detectors is given by,
The rms range for F18 is and the noncolinearity for a 1000 mm separations is
So, = 48.9965% is added to the system resolution relative to the detector resolution.
