RF Coil Lab

The RF Coil Laboratory in BMEII was initially established in 2010. This fully equipped electronics lab is available for RF coil building and troubleshooting.

The lab is equipped with a vector network analyzer, oscilloscopes, a circuit board printer, a 3D printer, a signal generator, DC power supplies, as well as other standard electronics equipment.

BMEII core staff, trainees, and faculty have produced numerous custom RF coils and components for basic and translational research projects. These include coils for high resolution imaging at 7T of the human cervical spine cord, brainstem, carotid arteries, and body, as well as a dedicated coil for rabbit cardiac imaging. Recently, a passive wireless RF array for enhancement of RF fields in the central nervous system was designed, prototyped, and tested in the facility.

In addition to RF hardware, users have also develop mechanical and electronic accessories that are utilized for specific experiments in the high magnet field environment of the MRI scanners.

Coil Inventory

3 Tesla (mMR, Research Skyra, Clinical Skyra)

Abbreviations: Tx (transmit), Rx (receive)

Note: Many 7T coils have multiple transmit elements connected in a fixed amplitude/phase relationship to a single transmit channel. For these coils, the number of driven elements is given, but “1ch Tx” is also noted. For parallel transmit coils, the number of transmit channels is noted.
