IMAGE PROCESSING DEVICE, IMAGE PROCESSING MODEL GENERATION DEVICE, LEARNING DATA GENERATION DEVICE, AND PROGRAM

Title:

IMAGE PROCESSING DEVICE, IMAGE PROCESSING MODEL GENERATION DEVICE, LEARNING DATA GENERATION DEVICE, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2021/177374

Kind Code:

A1

Abstract:

An acquisition unit of an image processing device acquires intended data that is three-dimensional medical image data from which an area of interest is to be extracted. A conversion unit: performs a conversion process so as to ensure that at least one of the size, direction, and position of the intended data coincides with standard data, which is three-dimensional medical data representing a standard, so that the degree of coincidence between the intended data and the standard data increases; and generates pre-converted data, which is three-dimensional medical data that has been subjected to the conversion process on the intended data. An area extraction unit inputs the pre-converted data to a pre-learned model that has been trained in advance in order to extract an area of interest included in three-dimensional medical image data from the three-dimensional medical image data, and extracts the area of interest included in the pre-converted data through computation by the pre-learned model.
