1H and Dual-Frequency RF Coils on Small-Animal Imaging Platforms (SAIP)

Versatile, Open, Robust, Economical Design

The CP litzcage is semi-open and mounted on an almost transparent, short coil form. The separate, removable, rf shield allows for full, convenient access to the coil area. The platform is usually supplied with a CP Litzcage rf coil with SNR typically 15% higher than that of conventional CP birdcages of similar dimensions. B1 homogeneity is typically 10-30% better, and the coil has superior B0 homogeneity.

Easy tuning

A unique symmetrizing circuit ensures the coil is easily tuned and matched to the full range of samples with negligible loss in efficiency, channel separation, or symmetry. Tuning range is much better than with conventional birdcages and tuning methods.

An adjustable headholder is available for 38 mm coils.

The headholder shown above is equipped with an adjustable toothbar and variable depth ear pins (which gently insert into the ear canals). Adjustments are simple – yet the result is gentle, secure immobilization of the head. Finally, the nose cup can be slid over the nose and attached to the anesthesia line.
