PURPOSE Design, validation and application of an accelerated fast spin-echo (FSE) variant that uses a split-echo approach for self-calibrated parallel imaging. METHODS For self-calibrated, split-echo FSE (SCSE-FSE), extra displacement gradients were incorporated into FSE to decompose odd and even echo groups which were independently phase encoded to derive coil sensitivity maps, and to genera...

PURPOSE To compare the detectability of vertebral metastatic disease on T1-weighted, short-inversion-time inversion recovery (STIR), fast spin-echo (FSE), fat-saturated FSE, and inversion recovery FSE (IRFSE) MR sequences using percent contrast and contrast-to-noise ratios. METHODS Patients with proved metastatic disease underwent imaging on a 1.5-T MR system with sagittal T1-weighted (800/20...

A dynamic optimization method was created to address the production schedule issue in an open-pit coal mine while taking into account characteristics of fuzzy structured element. The mining capacities all “geologically optimal push-back bodies” were then examined using moving cove method. One most crucial elements process scheduling is pricing. As a result, this work also presents technique for...

PURPOSE To compare T2-weighted conventional spin-echo (CSE), fast spin-echo (FSE), shorttau inversion recovery (STIR) FSE, and fluid-attenuated inversion recovery (FLAIR) FSE sequences in the assessment of cervical multiple sclerosis plaques. METHODS Twenty patients with clinically confirmed multiple sclerosis and signs of cervical cord involvement were examined on a 1.5-T MR system. Sagittal...

Introduction: Fast-spin echo (FSE) imaging is one of the most frequently used pulse sequences for brain imaging due to its scan time efficiency, good tissue contrast, and high effective resolution. Practical problems that occur are mostly due to patient motion, which leads to blurring and imaging ghosting (Fig. 1b). To make the acquisition robust to motion, the T2-w PROPELLER pulse sequence can...

Introduction Musculoskeletal MRI is commonly done with two-dimensional fast-spin-echo (2D-FSE) and multiple acquisition planes. This results in anisotropic voxels, partial volume artifact and slice gaps. Three-dimensional fast-spin-echo (3D-FSE-Cube), allows for isotropic voxel acquisition with FSE contrast, diminishing the drawbacks of 2D-FSE while reducing exam time and allowing for image ref...

Marine simulator has been widely used in seafarer training and examination. Besides, in order to reduce the human subjective influence during the examination, the automatic evaluation system for ship maneuvering based on the marine simulator has become more and more necessary. So, the general design idea of the automatic evaluation system of ship maneuvering is proposed. And, considering differ...

There exist problems in fuzzy finite element methods because technique of solving fuzzy equations is not perfect. For example, computation amount is too big and both sides of the equality are not exactly equal when solutions are substituted into the original equation. The concept of monosource fuzzy number is developed to simplify the calculation process of fuzzy equations. However the source o...

In this paper, an algorithm for VLSI standard cell placement for low power and high performance design is presented. This is a hard multiobjective combinatorial optimization problem with no known exact and efficient algorithm that can guarantee finding a solution of specific or desirable quality. Approximation iterative heuristics such as Simulated Evolution (SE) are best suited to perform an i...
