RF Coil Technology for Small-Animal MRI

A review of the theory, technology, and practice of RF coils for small-animal MRI is presented that includes a brief overview of MR S/N analysis and discussions of the various coils commonly used in small-animal MR – surface coils, linear volume coils, birdcages, and their derivatives. The scope is limited to mid-range coils – coils where the product (fd) of the frequency f and the coil diamete...

Novel Orthogonal Double Solenoid (ODS) Volume RF Coil for Small Animal Imaging

Introduction: Solenoids are known to be inherently high SNR coils that also generate highly homogeneous radio frequency magnetic (B1) fields[1]. The traditional solenoidal coil generates B1 field that is parallel to the static magnetic (B0) field. Hence, solenoidal RF coils currently in use for small animal imaging are typically designed for large bore clinical scanners, where the RF coil may b...

Superior Imaging with HTS RF Coil

For the past 30 years, a major focus for new MRI technology and products has been in the development of higher field strength magnets. The rational for this is the higher the field strength, the better the Signal-to-Noise (SNR) of the MR image. This trend comes to an end as the field strength reaches 3Telsa (T), the highest field permitted for clinical use by FDA, CE and other regulatory agenci...

An Efficient Metamaterial- Inspired Electrically-small Antenna

This article presents an inexpensive, efficient, and electrically-small antenna design that is based on a metamaterial-inspired structure driven by an electrically-small semi-circular loop antenna, which is coaxially-fed through a finite ground plane. The proposed antenna system is linearly scalable over a wide frequency spectrum. The design details and radiation characteristics of the antenna ...

Optimal self-calibration of tomographic reconstruction parameters in whole-body small animal optoacoustic imaging

In tomographic optoacoustic imaging, multiple parameters related to both light and ultrasound propagation characteristics of the medium need to be adequately selected in order to accurately recover maps of local optical absorbance. Speed of sound in the imaged object and surrounding medium is a key parameter conventionally assumed to be uniform. Mismatch between the actual and predicted speed o...
