| Abstract(in English) | In late years the MRI that is a tomogram technology using a magnetic resonance phenomenon attracts its attention. MRI acquires biological information as a complex signal, and the image reconstruction by the FFT. Therefore, a point image function after the FFT becomes clear and improvement of the space resolution if a period of enough length enters the measurement signal. In other words, an high magnetic field is essential to achieve high resolution in FFT. However, high magnetic fields of which leads to maintenance costs increase and upsizing of the device. In this study, we extend the NHA that is high accuracy signal analysis method to the complex signal. Then, we show the possibility of providing high definition image at low field MRI by the computer simulation that assumed ideal environment. |
