    摘要: A magnetic resonance system includes a magnetic resonance scanner having a multi-channel transmit coil or coil system and a magnetic resonance receive element; and a digital processor configured to perform an imaging process. The image process includes shimming the multi-channel transmit coil or coil system, acquiring a coil sensitivity map for the magnetic resonance receive element using the multi-channel transmit coil or coil system, acquiring a magnetic resonance image using the magnetic resonance receive element and the shimmed multi-channel transmit coil or coil system, and performing an intensity level correction on the acquired magnetic resonance image using the coil sensitivity map to generate a corrected magnetic resonance image.
