Atrial fibrillation is caused by some excited cardiac myocardium re-stimulated by the recurrent impulse that made the left atrium contraction irregularly. The changes of cardiac patterns could be recorded by the CT scan of the multi-slices and multi-frame technology. The abnormal rhythmic wall motion can be analyzed between the systolic of atrium and diastolic of atrium. This study has developed a...
The function of left atrium can be accurately estimated non-invasively using 4D CT cardiac images. A self-developed image analysis program will first reconstruct 3D volume of heart. Then, one may re-sample images for accurately deleting the 4 pulmonary veins from the atrium and set the boundary. With the prior processed information, the active contour methodology and seed regional growth methodology...
Evaluation of aorta morphology and function in presence of aneurysms or dissection is crucial for a correct treatment choice between surgical resection and percutaneous stent-graft deployment. We developed and tested a new method for automated dynamic aorta segmentation from computed tomography (CT) images from which static and dynamic parameters of aortic morphology and function can be automatically...
