How Analyze was Used
“CT volume data converted from original DICOM (digital imaging and communications in medicine) images were transferred to a separate workstation equipped with the software Analyze V 11.0 (AnalyzeDirect, Inc., Overland Park, KS, USA) for image post-processing and generation of 3D VIE images. Post-processing of CT data was performed with a CT number thresholding technique. Generation of VIE images of coronary plaques and coronary lumen depends on the selection of an appropriate CT threshold, which was determined by measuring the CT attenuation in the ascending aorta according to previous reports. An upper CT threshold of 150 to 200 HU was applied to remove the contrast-enhanced blood from the coronary artery for optimal demonstration of intraluminal views of coronary walls.”
