<p>PURPOSE: To remarkably shorten time required for acquiring MRI data by calculating multiple Fourier projection except for a single NMR RF response through an MRI reconstitution algorithm. CONSTITUTION: An RF channel circuit is usually provided with an extremely complicated circuit. In order to improve time for data acquisition without requiring any special cost, it is necessary to execute deformation inside a conventional MRI processing system. Therefore, respective additional reception coils are provided with additional RF signal processing channels. Additional data are used while a little changing the MRI reconstitution algorithm to be programmed and executed inside an image processor 108. The MRI image processor 108 receives digital data expressing the NMR RF response from an object 110 under observation through multiplex Fourier transforming processing, calculates a digital visible image and displays this image on a display 112. Thus, time can be remarkably economized.</p> |
