A medical image processing apparatus according to a present embodiment includes processing circuitry. The processing circuitry is configured to accept an operation for a region of interest (ROI) GUI and a guide GUI on a screen on which a medical image is displayed, the ROI GUI being for setting a ROI on the medical image, the guide GUI being for guiding a setting of the ROI on the medical image. The processing circuitry is configured to decide whether to move the ROI GUI and the guide GUI in a manner interlocked with each other or not according to a preset condition, when a turning operation or a sliding operation for any one of the ROI GUI and the guide GUI is accepted.

Medical image processing apparatus, magnetic resonance imaging apparatus and medical image processing method

A magnetic resonance imaging apparatus according to an embodiment includes processing circuitry. By using image data of a subject acquired by performing a first imaging process, the processing circuitry is configured to detect a first region including at least a part of a first site, the first site and a second site having a symmetrical relationship with each other in the subject. The processing circuitry is configured to derive a second region including at least a part of the second site on the basis of the first region. The processing circuitry is configured to set a Radio Frequency (RF) pulse application region used for performing a second imaging process, on the basis of the second region.

Magnetic resonance imaging apparatus

A magnetic resonance imaging apparatus according to an embodiment includes processing circuitry. The processing circuitry generates an image based on a magnetic resonance signal from a subject. The processing circuitry generates a susceptibility image representing magnetic susceptibility of the subject from a phase component contained in a plurality of pixels in the image. The processing circuitry generates an artifact component of the susceptibility image based on a frequency signal obtained by frequency transform of the susceptibility image. The processing circuitry generates an artifact component-removed susceptibility image by removing the artifact component from a susceptibility image generated based on the magnetic resonance signal.
