Medical data processing apparatus, magnetic resonance imaging apparatus, and learned model generating method

A magnetic resonance imaging apparatus comprising:

• a memory configured to store a learned model including an input layer to which first k-space data or MR image data, and second k-space data or MR image data relating to an imaging target the same as the first k-space data or MR image data and an imaging parameter different from the first k-space data or MR image data are inputted, an output layer from which third k-space data or MR image data having a missing portion of the first k-space data or MR image data restored is output, and at least one intermediate layer arranged between the input layer and the output layer, and
• processing circuitry configured to:
• acquire first k-space data relating to a first imaging parameter and second k-space data relating to a second imaging parameter that is different from the first imaging parameter, by performing MR imaging on a subject, and
• generate third k-space data or MR image data relating to the subject in accordance with the learned model, from the acquired k-space data or the MR image data based on the acquired k-space data and the acquired second k-space data or the MR image data based on the acquired k-space data.
