Abstract
A composite gradient system is described, including a body gradient system and an insert gradient system, in which the body gradient system and the insert gradient system can be driven independently and simultaneously. The composite gradient system can provide an operator with the flexibility of imaging a subject using the body gradient system alone, the insert gradient system alone, or both gradient systems simultaneously, and therefore enjoy the advantages of each gradient system. In some embodiments, the body gradient system and the insert gradient system may be driven concurrently during an imaging sequence to produce composite magnetic field gradients having high amplitude and/or fast slew rate, resulting in high image resolution and/or fast image acquisition. In some embodiments, a subject may be imaged using the body gradient system alone while leaving the insert gradient system in place.
