Adapted Transfer Function Design for Coronary Artery Evaluation
نویسندگان
چکیده
We present an approach for adapted transfer function (TF) specification to highlight pathologic changes of the coronary artery vessel wall based on contrast medium-enhanced computed tomography (CT) datasets. The TFs are combined with common visualization techniques for the evaluation of coronary arteries in CT image data. The presented mapping of CT values in Hounsfield Units (HU) to optical properties such as color and opacity leads to a different color coding for different plaque types.

Automatic Transfer Function Specification for Visual Emphasis of Coronary Artery Plaque
Cardiovascular imaging with current multislice spiral computed tomography (MSCT) technology enables a noninvasive evaluation of the coronary arteries. Contrast-enhanced MSCT angiography with high spatial resolution allows for a segmentation of the coronary artery tree. We present an automatically adapted transfer function (TF) specification to highlight pathologic changes of the vessel wall bas...
متن کاملEvaluation of strain and strain rate parameters using two-dimensional speckle-tracking echocardiography in patients with coronary artery disease (Research Article)
The study aimed was to measure left ventricular (LV) strain using speckle tracking echocardiography (STE) for assessment of LV function. Eighty-two subjects (mean age 57±9 years) with suspected chest pain underwent two-dimensional (2D)-echocardiography before coronary angiography. Conventional echocardiographic parameters were used for the assessment of LV function. Longitudinal strain and its ...
متن کاملEvaluation of Factors Influencing Liver Function Test in On-Pump Coronary Artery Bypass Graft Surgery
Background: Liver dysfunction during on-pump coronary artery bypass graft surgery (CABG) is a rare complication but is associated with significant morbidity and mortality. The ability to identify high-risk patients may be helpful in planning appropriate management strategies. We aimed to evaluate the factors influencing liver function tests during on-pump CABG.Methods: In 146 patients scheduled...
متن کاملEvaluation of Extracellular Circulating Human MicroRNA-197 as a Target Biomarker in Patients with Coronary Artery Disease
Background: Coronary Artery Disease (CAD) refers to the reduction or blockage of all or part of the coronary arteries due to the process of atherosclerosis or the presence of a clot. The aim of this study was to investigate the association of serum miR-197 as a diagnostic index in patients with coronary artery disease. Methods: In this study, 100 patients with CAD were selected. Extraction of...
متن کاملEvaluation of Cognitive Complications Following General Anesthesia in Patients Undergoing Coronary Artery Bypass Graft Surgery Using Wisconsin Test
Background and Aim: One of the complications of cardiopulmonary bypass (CPB) surgery is cognitive function decline. Due to the importance and direct effects of cognitive function on the quality of human life, this study was designed to compare the executive function of young CPB patients with the age range of 30-55 years one year after undergoing the surgery with healthy subjects. Materials and...
