The following Pro.specta Emission Computed Tomography Systems that were manufactured with an SLD Look Ahead Optical Sensor Assembly: (a) Symbia Pro.specta Q3, Model 11364751; (b) Symbia Pro.specta X3, Model 11364752; (c) Symbia Pro.specta X7, Model 11364753.

Reason: 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.
