Claim 6:
7. An image processing apparatus for performing processing of increasing a resolution on a reconstructed image captured by a magnetic resonance imaging device by using a point spread function, the image processing apparatus comprising:
an image processing unit configured to perform processing of increasing a resolution on the reconstructed image by using the point spread function, the image processing unit including:
an acquisition unit configured to acquire the point spread function; and
a storage unit configured to store the acquired point spread function, wherein
the point spread function is a signal obtained by, after a phantom or a subject disposed in an imaging space of the magnetic resonance imaging device is irradiated with a high-frequency magnetic field, acquiring a nuclear magnetic resonance signal from the phantom without applying frequency encoding and phase encoding, and performing Fourier transform on the acquired nuclear magnetic resonance signal, and
the image processing unit generates an image with a higher resolution by performing deconvolution calculation of the image of the subject and the point spread function.
