MEDICAL IMAGING APPARATUS, IMAGE PROCESSING APPARATUS, AND IMAGE PROCESSING METHOD
First Claim
1. A medical imaging apparatus comprising:
- an imaging unit that collects image data of a subject; and
an image processing unit that performs a process of extracting a plane of a target plane including a predetermined structure from the image data collected by the imaging unit,wherein the image processing unit includes a learning model storage unit that stores a learning model learned using learning data, a structure extraction unit that detects a region of the predetermined structure included in the plane by applying the learning model to a plurality of planes obtained from the image data, and a plane extraction unit that extracts the plane of the target plane from the plurality of planes based on the detected region of the predetermined structure, andthe learning data includes a target plane for learning including an image of the structure imaged in advance for the target plane, and a region-of-interest plane for learning obtained by cutting out and enlarging a region of interest including the structure in the target plane for learning.

Abstract
Provided is a technology for extracting an image of a target plane from 2D or 3D image data acquired by a medical imaging apparatus with a small amount of computation and at high speed. A plane of a target plane including a predetermined structure is extracted from image data of a subject. A region of the predetermined structure included in the plane is detected by applying a learning model learned using learning data including a target plane for learning including an image of the structure and a region-of-interest plane for learning obtained by cutting out and enlarging a partial region including the structure in the target plane for learning to a plurality of planes obtained from the image data, and the plane of the target plane is extracted based on the detected region of the predetermined structure.
