| Research Abstract |
For previously developed in-house software, (1) we implemented modeling of gradient magnetic field and confirmed the effect with a digital phantom (2) customizable RF pulse, pulse sequences, TR, TE, FA, BW, slew rate and Gmax were implemented (3) ‘save as movie’ feature that enhanced utility of the software were implemented. A new software that simulate macroscopic behaviorof the spins and were used to simulate signal behavior with multiple IR pulses. By introduction of a powerful workstation, the number of spins for simulation increased to10,000. These results were reported both in domestic and international conferences (JRC and RSNA, respectively). Off-line reconstruction software was developed. By using compressed sensing technique, clear visualization of cerebral arteries was achieved by using only 20% of full 3D-MRA data.
