Our composite system has the distinct advantage that both of standard and insert gradient systems can be operated simultaneously and/or independently. With simultaneous acquisition, the gradient strength available from either system alone can be increased. The use of composite gradients will allow high resolution SSFP images without increasing TR or bandwidth, allowing for improved inner ear imaging. To test the utility of this composite gradient system we scanned the temporal bone of guinea pigs with the composite and body gradients only and compared image quality.
