Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Area of Science:

Magnetic Resonance Imaging (MRI)
Radiofrequency (RF) Coil Engineering

Background:

High field (9.4T) MRI offers superior resolution for small animal studies.
Optimizing RF coil performance, including field homogeneity and signal penetration, is critical for image quality.

Purpose of the Study:

To design and construct a novel 8-element transceive volume-array coil for large rat MRI at 9.4T.
To investigate the impact of angularly oriented coil elements on RF penetration and mutual coupling.

Main Methods:

Design and fabrication of a dedicated 9.4T shielded 8-element transceive volume-array coil.
Utilizing angularly oriented radiating structured coil elements.
Experimental evaluation of the coil's performance, including B(1) field homogeneity and suitability for parallel imaging.

Main Results:

The prototype coil demonstrated increased RF penetration depth.
Minimized mutual coupling between coil elements was achieved.
The coil produced a homogenous B(1) field.
The coil proved well-suited for Transmit SENSE and GRAPPA parallel imaging.

Conclusions:

Angularly oriented coil elements are effective in improving RF penetration and reducing mutual coupling in high-field MRI coils.
The developed 9.4T 8-element volume-array coil is a promising tool for advanced rat MRI applications, supporting techniques like Transmit SENSE and GRAPPA.
