Real-time MR imaging would allow essentially instantaneous viewing of dynamic processes, interventional procedures, and the effects of changes to variables associated with MR image quality and slice positioning. No dedicated system has been capable of producing true real-time MRI imaging (reconstructing at least 30 frames per second). A digital reconstruction system capable of true real-time Magnetic Resonance Imaging (MRI) was demonstrated in this project. The demonstration included contributions to the design of the system, constructing the system, interfacing to a MRI acquisition system, writing pulse programs to produce MRI data, and providing an analysis of the results. The system, as configured in this project, reconstructed 128-by-128 pixel images at 122 frames per second using the two-dimensional (2-D) fast Fourier transform (FFT) reconstruction algorithm. The system consisted of four boards that plug into the bus of a personal computer (PC). The PC's purpose was to provide an initial configuration for the boards, which then performed their functions independent of the PC. Real-time MR imaging could be accomplished with this system when real-time data acquisition (at least 30 frames per second) is provided.
