MR Instruments

This Minneapolis developer of MRI coils and accessories will introduce a new transmit-and-receive head coil for 3-tesla scanners, as well as a parallel transceiver device for ultrahigh-field magnets.

The company's Dual Tune head coil is a circular-polarized transmit-and-receive coil in MR Instruments' transverse electromagnetic (TEM) product family. Designed for multinuclear spectroscopy and proton imaging, the coil's X nucleus frequency can be selected from ³¹P, ¹³C, ²³Na, and ¹²⁹Xe. The coil has been cleared by the U.S. Food and Drug Administration, and is currently available in the U.S. International shipments will begin in 2007.

MR Instruments will also introduce a parallel transceiver designed for scanners at field strengths of 3 tesla and higher. The transceiver reduces the time of the delivered radiofrequency (RF) signal, and is useful for transmit SENSE parallel-imaging applications in head and neck imaging, the company said.

The transceiver allows superior RF field uniformity at higher field strengths, reduces RF power requirements, and allows more anatomical coverage in less time. MR Instruments will show the transceiver as a work-in-progress, with product availability in the U.S. and internationally expected in 2007.
