Magnetic Resonance Imaging (MRI) is one of the powerful techniques to acquire in vivo information. However, to obtain a three dimensional fine image of the whole brain, it takes thirty minutes to forty minutes by using a current standard MRI scanner. Thus, to mitigate the inconvenience of the patient, further reduction of imaging time is required. For the past 10 years, Compressed Sensing (CS) has contributed to research for acceleration and high definition of MRI by means of information processing. However, CS has a disadvantage that the computational complexity is the order of cubic of the number of samples. Thus, in the case of high resolution images, it requires a reconstruction time longer than the reduced inspection time. Recently, deep learning based approach has been intensively studied for this problem. In this research, we propose a deep learning method, in which we employ a super-resolution (SR) method based on convolutional neural networks. In our method, the SR processes are applied to various resolution images obtained from the input signal. We report the results of adapting the proposed method to MRA (Magnetic Resonance Angiography) images. |
