Magnetic resonance fingerprinting is a technique for acquiring and processing MR data that simultaneously provides quantitative maps of different tissue parameters through pattern recognition algorithm.A predefined dictionary models the possible signal evolutions simulated using Bloch equations with combinations various completed by computing inner product between observed each predicted signals within dictionary.Though this matching algorithm has been shown to accurately predict interest,...
Purpose To reduce the acquisition time needed to obtain reliable parametric maps with Magnetic Resonance Fingerprinting. Methods An iterative‐denoising algorithm is initialized by reconstructing MRF image series at low resolution. For subsequent iterations, method enforces pixel‐wise fidelity best‐matching dictionary template then acquired data slightly higher spatial After convergence, desirable resolution are obtained through matching of final series. The proposed was evaluated on phantom...
Background Conventional MRI can be limited in detecting subtle epileptic lesions or identifying active/epileptic among widespread, multifocal lesions. Purpose We developed a high‐resolution 3D MR fingerprinting (MRF) protocol to simultaneously provide quantitative T 1 , 2 proton density, and tissue fraction maps for detection characterization of Study type Prospective. Population National Institute Standards Technology (NIST) / International Society Magnetic Resonance Medicine (ISMRM)...
Purpose Unpleasant acoustic noise is a drawback of almost every MRI scan. Instead reducing to improve patient comfort, we propose technique for mitigating the problem by producing musical sounds directly from switching magnetic fields while simultaneously quantifying multiple important tissue properties. Theory and Methods MP3 music files were converted arbitrary encoding gradients, which then used with varying flip angles repetition times in two‐ three‐dimensional resonance fingerprinting...
Purpose The purpose of this study is to increase the robustness MR fingerprinting (MRF) toward subject motion. Methods A novel reconstruction algorithm, MOtion insensitive MRF (MORF), was developed, which uses an iterative based retrospective motion correction approach. Each iteration loops through following steps: pattern recognition, metric identification corrupted frames, registration estimation, and compensated data consistency verification. proposed algorithm validated using in vivo 2D...
The objective of this study was to demonstrate the feasibility improving perceived acoustic comfort for a standard clinical magnetic resonance imaging protocol via gradient wave form optimization and validate parallel as means achieve further reduction noise.The forms T2 axial turbo spin-echo (TSE) sequence in head examinations were modified performance while attempting keep total acquisition inter-echo spacing same. Parallel then used double allow optimization. Along with comparative noise...
We propose the customization of a commercially-available phantom design to be used for QSM reproducibility research with long-term stability, allowing reproduction itself commercially. The proposed is based on master-dilution Gadolinium in pure water vials, offering theoretical susceptibility range chosen match normal tissue and common pathologies brain. evaluate suitability reproducible different sequences, orientation within scanner regularization algorithms.
Isolators play a critical role in protecting both the product and environment, as well personnel involved pharmaceutical manufacturing, analytical procedures sterility testing. Gloves attached to windows doors of isolator are designed facilitate intervention, testing safety. However, due their inherent characteristics vulnerability puncture or loss integrity, they recognised significant potential source contamination. In addition possible pathways contamination transfer, size glove holes...

Secondly, it present application our mobile robotic problem, way we tested simulated environment close real and, through two examples different situations, advantages over...
Abstract Metallic parts of aircrafts that are used for fuel tanks areas or even the fuselage can suffer from severe direct damage due to lightning strikes. Laboratory tests imitating strikes follow standard regulations requirements prescribe current waveforms structure must resist depending on zone airplane.
