We present a method to automatically register cerebral 2D digital subtraction angiography sequences (2D-DSA) to 3D rotational Xray angiography (3D-RA) volumes. The application is the validation of blood flow simulations for aneurysm treatment. We compute projection images of 3D-RA data sets and compare them to the 2D-DSA images. A three-step strategy is presented to calculate the registration w...

Selective spinal cord angiography is the estab lished method for evaluating patients with vascular lesions of the cord. This technique is technically demanding , and the examination takes considerab le amounts of time and rad iation [1]. Digital subtraction angiography (DSA) with venous injections produces arterial images with dec reased patient risk . This procedure is also valuable in conjunc...

Audience attention is vital in Digital Signage Advertising (DSA), as it has a significant impact on the pricing decision to advertise those media. Various environmental factors affect audience level toward advertising signage. Fixed-price strategies, which have been applied DSA for decisions, are generally inefficient at maximizing potential profit of service provider, that could changing fast ...

The researchers aimed to study the nonlinear fractional order model of malaria infection based on Caputo-Fabrizio derivative. homotopy analysis transform method (HATM) is applied floating-point arithmetic (FPA) and discrete stochastic (DSA). In FPA, show accuracy we use absolute error which depends exact solution a positive value ?. Because in real life problems do not have optimal ?, need intr...

We propose new fast implementation method of public-key cryptography suitable for DSP. We improved modular multiplication and elliptic doubling to increase speed. For modular multiplication, we devised a new implementation method of Montgomery multiplication, which is suitable for pipeline processing. For elliptic doubling, we devised an improved computation for the number of multiplications an...

With the development of the single antigen beads assay, the role of donor specific alloantibody (DSA) against human leukocyte antigens in kidney transplantation (KT) has been highlighted. This study aimed to investigate the clinical significance of DQ-DSA detected at renal allograft biopsy. We evaluated 263 KT recipients who underwent allograft biopsy and DSA detection at the same time. Among t...

BACKGROUND AND PURPOSE Although digital subtraction angiography (DSA) is considered the criterion standard for depiction of intracranial aneurysms, it is often difficult to determine the relationship of overlapping vessels to aneurysms when using 2D DSA. We compared 2D and 3D DSA in evaluation of intracranial aneurysms. METHODS Thirty-six consecutive patients with cerebral aneurysms underwent...

Fukunaga–Koontz Transform (FKT) is a famous feature extraction method in statistical pattern recognition, which aims to find a set of vectors that have the best representative power for one class while the poorest representative power for the other class. Li and Savvides [1] propose a one-against-all strategy to deal with multi-class problems, in which the two-class FKT method can be directly a...

UNLABELLED Anti-HLA donor-specific antibodies (DSA) identified by single antigen bead array (SAB) are questioned for their excess in sensitivity and lack of event prediction after transplantation. POPULATION AND METHODS We retrospectively evaluated specific types of preformed DSA (class I, class II or C1q-fixing) and their impact on graft survival. Kidney transplantations performed across neg...

OBJECTIVE We applied optical flow method (OFM) to quantify relative velocities of blood flow using digital subtraction angiography (DSA) in the vascular analysis of hepatocellular carcinoma (HCC) patients who underwent transarterial chemoembolization (TACE) treatment. METHODS A total of 40 HCC patients treated by TACE were analyzed in this study. DSA imaging with a 12-inch field of view, 1024...
