RE: ClinicalConnect: Important Information About Image Viewer

ClinicalConnect includes two image viewers depending on the source of the image. Please be advised of the following information recently received about the potential to display inaccurate measurement on images in GE's Centricity ZFP Viewer, which is used to view diagnostic images from hospitals in Ontario Health West Region (South West Ontario).

Safety Issue #1: Distance and Area measurement values can display inaccurately on images that are scaled down from their original resolution.

Action: Do not utilize any measurements when the "Lossy" overlay is displayed in the lower left of the viewport and, when you hover over the word "Lossy", it displays the tooltip box with the phrase "image scaled down from its original resolution".

Safety Issue #2: When the image contains non-squared pixels including DICOM Gray Scale Presentation State (GSPS), all measurements displayed in the viewer as well as the scale marker are inaccurate.

Action: Do not perform any measurement on non-squared pixel images. Always confirm critical diagnostic measurements by other means (i.e using a fiducial marker of known size) or confirm with acquisition site.

Please refer to the User Manual available in the GE Centricity ZFP Viewer about the Lossy Function, and also read the corresponding diagnostic imaging report that's available in ClinicalConnect.



Notice will be provided when GE has corrected the issue.
