Abstract
The present invention provides for a body coil modeled after a birdcage coil and based on a ladder network design. A fixed number of single loop coils (N) are equally spaced around a cylinder. These coils must be driven 360°/N out of phase with respect to each other azimuthally. Each phase must increase 360°/N as azimuthally in order for single loop coil currents to mimic currents commonly seen in the quadrature birdcage coil. A switching circuit is necessary to change the transmit coil configuration and the N channel for phased array reception. This type of coil eliminates the otherwise necessary need to decouple the transmit coil from the receiver coils, but preserves the SNR benefit of having multiple receiver coils. This type of coil will improve SNR over ordinary volume coils and may be necessary imaging large patients where space around the patient is at a minimum.
