Siemens Pro.specta CT Scanners: Risk of Reduced Image Quality in Scans
Siemens recalls specific Pro.specta Emission Computed Tomography Systems with SLD Look Ahead Optical Sensor Assembly that may cause reduced image resolution during scans. Affected models and serial numbers listed in the recall notice.
During a whole-body planar scan with auto-contour, there is a possibility the short-linear drive (SLD) look-ahead sensors may trigger earlier than expected and may result in detector 1 positioning further from the patient than needed leading to a reduction in image resolution.
