Hermes Medical Solutions AB, FSN0066683, Hybrid Recon

When reconstructing a SPECT/CT study, in some cases, the SPECT and CT series are not correctly aligned. This may be due to separately performed acquisitions, or due to the camera operator re-setting the reference point (landmark) between SPECT and CT acquisitions. Normally, the Hybrid Recon application warns the user if the Frames of Reference do not match, however in some configurations this warning message may be turned off. If these conditions are met, then the SPECT reconstruction might not be properly aligned to the CT. This will often be obvious during the initial QC fused display and during final review, but there is a small chance that it might go unnoticed.
