A Subpixel Edge Detector Applied to Aortic Dissection Detection
[chapter]
2012
Lecture Notes in Computer Science
Preserved Fulltext
The aim of this paper is to contribute to its diagnosis, detecting the dissection edges inside the aorta. ...
The aortic dissection is a disease that can cause a deadly situation, even with a correct treatment. ...
In this set of tests, the NRAD method is first applied to reduce the noise, and the subpixel method is applied to detect the edges. ...

Approach: The review is divided into five major sections, each linked to a key innovation in CT: helical spiral data acquisition, multi-slice CT, wide-cone CT, dual-source CT, and spectral CT. ...
Purpose: We provide a review of the key computed tomography (CT) technologies developed since the late 1980s and offer an overview of one of the future technologies under development. ...
A potential subpixel structure is indicated for the three left detector cells. ...

Thus, the reliable detection of the aortic cross sectional area over the entire heart cycle was possible for both MR and CT with a relative error of about 1% depending on image quality. ...
Determination of Aortic Elasticity from MR-and CT-Images Using an Automatic Active Contour Model The possibility to monitor changes in aortic elasticity in humans has important applications for clinical ...
In order to get subpixel resolution, bilinear interpolation was applied to the pixels. ...

Since we focus on objects that have a constrained shape and move according to specific patterns, it seems natural to approach the detection, segmentation, and tracking problems with model-based techniques ...
Then, we extend our model to a fully parametric 3D design. ...
I do not want to forget all my friends from my universities (FME, ETSETB, and IIT). Without them, my geekiness would not be so strong. ...
