Below are links to system (extrinsic) resolution measurements for CardiArc®. Please note that these are extrinsic values, i.e. full system including collimation, rather than the intrinsic (detector-only) measurements often advertised.
Measurements of planar resolution
Measurements of reconstructed SPECT resolution

Jaszczak phantom image comparisons
Points to note:
- Both planar and reconstructed system resolutions with CardiArc exceed that of any comparable SPECT system.
CardiArc's reconstructed resolution at the depth of the heart in the chest exceeds that of any PET scanner available today.
These are extrinsic resolution measurements, made with all collimation in position, i.e. the actual configuration for clinical imaging.
