Adaptive filtering for high resolution magnetic resonance images
Journal of Magnetic Resonance Imaging, 1996AbstractWe present a study of least mean square (LMS) based adaptive filters for high resolution magnetic resonance (MR) images to improve signal‐to‐noise ratio (SNR) while maintaining sharp edges. Five variations of a new technique that senses the type of noise or the presence of an edge in the filtering window, called adaptive filtering with noise ...

High‐Resolution Magnetic Resonance Imaging of Human Cochlea
The Laryngoscope, 2002AbstractObjectives High‐resolution MRI (MRI) of human inner ear structures provides several advantages over other imaging modalities. High‐resolution visualization of inner ear ultrastructure in a noninvasive manner may provide important information about inner ear disease that is not obtainable in other ways. The study was performed to demonstrate the

High Resolution, Dynamic, Magnetic Resonance Imaging in Complicated Strabismus
Journal of Pediatric Ophthalmology & Strabismus, 1996ABSTRACT Strabismus cases, especially after previous surgery or trauma to extraocular muscles, often present diagnostic challenges. Conventional clinical tests are helpful in some cases but may be inconclusive. High resolution, dynamic, orbital magnetic resonance imaging (MRI) may yield additional critical information about orbital and ...

High Resolution Magnetic Resonance Imaging of Neurovascular Orbital Anatomy
Ophthalmology, 1997This study describes the magnetic resonance imaging (MRI) anatomy of the blood vessels and nerves of the orbit to provide a morphological basis for the interpretation of clinical findings.Seven volunteers aged 29 to 54 years underwent high-resolution MRI of the orbit on a 1 Tesla unit (Impact, Siemens, Germany).

Clinical applications of high-resolution ocular magnetic resonance imaging
Japanese Journal of Radiology, 2012Magnetic resonance imaging (MRI) using fast sequences with subjects staring at a target can provide motion-free ocular images, and small receiver surface coils make it possible to produce ocular images with high spatial resolution. MRI using half-Fourier single-shot rapid acquisition with a relaxation enhancement sequence as a fast T2-weighted imaging ...

High-resolution magnetic resonance instant imaging
Physica B: Condensed Matter, 2007Multiphase sensitive detection at constant time on the free induction decay of the magnetization after an RF-pulse and phase encoding the signals in relation to the detectors result in high-resolution magnetic resonance instant imaging. The field gradient for spatial resolution is assumed to be static and linear.

High-resolution magnetic resonance imaging of carotid atherosclerosis
International Congress Series, 2004Abstract High-resolution imaging techniques that permit serial, in vivo examination of the atherosclerotic plaque are needed to better understand the mechanisms involved in the progression of stable, early lesions into high-risk plaques in humans. Such an imaging tool would serve as a bridge between what is learned in the laboratory and the clinical ...

High Resolution Magnetic Resonance Imaging Evaluation of Cheese
Journal of Food Science, 2003ABSTRACT: The curd granules/joints structure of the Emmentaler was observed by NMR micro‐imaging during the different stages of cheesemaking. During the ripening process, many carbon dioxyde microbubbles have been visualized inside the curd grains, as well as some volumes of fat outside the grains. At the end of

High-Resolution Magnetic Resonance Imaging of the Human Median Nerve
Neurorehabilitation and Neural Repair, 2004Objectives. It is widely accepted that peripheral nerve repairs performed within 6 weeks of injury have much better outcomes than those performed at later dates. However, there is no diagnostic technique that can determine if a traumatic peripheral nerve injury requires surgical intervention in the early postinjury phase. The objective of this article
