Provided are a magnetic resonance imaging apparatus (10), an image processing apparatus, an image processing method, a program, and a trained model set that can reduce a training cost of a trained model. A magnetic resonance imaging apparatus (10) according to the present disclosure includes a processor (202) that selects a trained model corresponding to an unmeasured percentage from among a plurality of trained models and estimates data of an unmeasured region using the selected trained model, in which at least one of the number of layers, a kernel size, or the number of channels of convolutional processing is smaller in a first trained model corresponding to a first unmeasured percentage among the plurality of trained models than in a second trained model corresponding to a second unmeasured percentage that is relatively higher than the first unmeasured percentage.

Provided are a magnetic resonance that can obtain a reconstruction image in which resolution of an unmeasured region is improved while an increase in noise in a measurement region is suppressed. A magnetic resonance imaging apparatus (10) according to the present disclosure estimates a second reconstruction image by inputting a first reconstruction image obtained by reconstructing data of a k-space including partial measurement data of a measurement region to a trained model, and generates a fourth reconstruction image by reconstructing the data of the k-space including first measurement region data of the measurement region of the k-space obtained by performing a Fourier transform on the second reconstruction image and first unmeasured region data of the unmeasured region of the k-space obtained by performing a Fourier transform on a third reconstruction image obtained by performing edge enhancement filter processing on the second reconstruction image.

Provided are a magnetic resonance imaging apparatus (10), an image processing apparatus, an image processing method, a program, and a generation method of a trained model that can suppress the occurrence of striped noise in an image reconstructed based on partial k-space data acquired within an asymmetrical measurement region of the k-space and generate a high-quality image. A magnetic resonance imaging apparatus (10) estimates a second reconstruction image by inputting a first reconstruction image to a first trained model that has been trained to receive an input of an input image in which data of a k-space including data of a measurement region is reconstructed and output a noise-reduced image in which the data of the k-space including the data of the measurement region in which noise is reduced is reconstructed, and estimates data of an unmeasured region other than the measurement region from the second reconstruction image.

A magnetic resonance imaging apparatus (10) includes a processor (202) which is configured to: acquire second partial measurement data of a second measurement region excluding a second unmeasured region that is asymmetrical and arbitrarily set for a second k-space; fill the second unmeasured region with zero data and generate data of the second k-space consisting of the second partial measurement data and the zero data filling the second unmeasured region; and when second proportion of the second unmeasured region to an entire region of the second k-space is different from a first proportion of a first unmeasured region to an entire region of a first k-space corresponding to a training image used for training a trained model, generate data of a third k-space by filling an outer region of the second k-space with zero data such that the second proportion becomes the first proportion.
