Magnetic Resonance Imaging of Osteochondral Lesions of the Talus: Comparison Between Small FOV Surface Coil with BLADE and Boot-Shape Coil Without BLADE

Static Coil Design Considerations for the Magnetic Resonance Imaging

One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...

Surface coil magnetic resonance imaging.

Surface-coil magnetic resonance imaging of the internal auditory canal.

Computed tomography is effective for detecting acoustic neuromas, but not for resolving individual nerves in the internal auditory canal. Surface-coil magnetic resonance (MR) images of the internal auditory canal were obtained using a 1.5 T superconducting magnet, a 13.5-cm-diameter surface coil, 3- and 5-mm-thick slices, and partial-saturation pulse sequences. Cranial nerves VII and VIII (thre...

Slotted surface coil for magnetic resonance imaging at 4T

Synopsis. A slotted surface coil, inspired on the cavity magnetron was developed for magnetic resonance imaging (MRI) at 4T. Imaging tests using a saline phantom demonstrated that the slotted surface coil has deeper RF-sensitivity than the single-loop RF-coil. High quality images of two rats were acquired simultaneously using standard spin-echo pulse sequences, demonstrating that the slotted su...

High-Tc Superconducting Surface Coil for 2 Tesla Magnetic Resonance Imaging of Small Animals

T h e p e r f o r m a n c e o f s m a I I v o I u m e Magnetic Resonance Imaging ( M R I ) d e p e n d s on t h e s y s t e m n o i s e determined by noise of a probe and/or of a preamplifier (not by the body noise). Several demonstrations confirmed that, for selected applications, high-TC superconductor MRI receiver coils have superior properties to those of comparable copper coils. W e report...
