摘要： A magnetic resonance imaging apparatus acquires magnetic resonance signals by the PI method using an RF coil unit having basic coils serving as surface coils which are arrayed with at least two coils along a static magnetic field direction (z direction) and at least two coils alone each of two orthogonal x, y directions. The coils are divided into an upper unit and a lower unit. The upper unit and lower unit are fixed by a band or the like to allow them to be mounted on an object to be examined. The signals detected by the respective surface coils are sent to a data processing system through independent receiver units and formed into a magnetic resonance image.

摘要： A magnetic resonance imaging system includes an MR signal reception apparatus comprising a receiving multi-coil and a switchover member. The receiving multi-coil receives MR signals and is composed of a plurality of element coils. The switchover member is configured to switch reception states of the MR signals received by the plurality of element coils in response to imaging conditions. The switchover member connects output paths of the MR signals from the plurality of element coils to a receiver, to reception channels in the receiver in response to the imaging conditions. The reception channels is less in number than the element coils. The imaging conditions are for example directed to parallel MR imaging.
