ABSTRACT:
An image reconstructing operation unit reconstructs an image by a two- or three-dimensional Fourier transform. The unit comprises a plurality of operating mechanisms for performing an operation to reconstruct an image, a plurality of local memory mechanisms, provided correspondingly to the operating mechanisms, provided correspondingly to the operating mechanisms, for storing data used in the operations and the operation results, a shared memory mechanism for storing data after the first- and second-dimension processes and the first-, second-, and third-dimension processes, a data transmission mechanism for transmitting data between the local memory mechanism and the shared memory mechanism, and an instruction control mechanism for controlling the operation of each mechanism and its timing. Operations performed by the operating mechanisms in the first-, second-, and third-dimension data processes are carried out in parallel with the data transmission between the local memory mechanism and the shared memory mechanism. Thus, images can be reconstructed at a high speed by an NMR imaging device.
