Abstract: The present disclosure makes it possible to acquire an image of high quality while shorten an imaging time by an MRI device. A data acquisition unit (11) acquires low-density sampling k-space raw data obtained by imaging a subject while reducing the number of measurement points by the MRI device, and outputs input data (IN) based on the low-density sampling k-space raw data. An inference processing unit (12) performs inference processing by inputting the input data (IN) to a trained model, and outputs restored image data (IMG) in which the image quality reduced by reducing the number of measurement points has been restored. An image display unit (13) displays the restored image data (IMG).

Abstract: A data acquisition unit acquires input data. An estimation unit estimates information relating to an estimation object by inputting the input data into a trained model. An image display unit displays the estimation information and the reason for estimation. The trained model includes a plurality of modularized networks constructed such that each of the modularized networks are trained in advance by different characteristics of the estimation object in image data for first training and estimation, and a fusion network for estimating information relating to the estimation object in input images constructed such that a plurality of output signals obtained by inputting image data for the second training and estimation into the plural modularized networks are inputted.
