LEARNING DEVICE, LEARNING METHOD, LEARNING DEVICE OPERATION PROGRAM, TRAINING DATA GENERATION DEVICE, MACHINE LEARNING MODEL AND MEDICAL IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/176813
Kind Code:
A1
Abstract:
A learning device for training a machine learning model for deriving the imaging direction and imaging site of a virtual cassette imaging subject which is depicted on a virtual cassette camera image, with the input thereof being a camera image obtained by imaging an imaging subject positioned relative to a medical imaging device using an optical camera, said learning device having a processor and a memory which is connected to or built into a virtual cassette processor, wherein: the virtual cassette processor generates, for each combination of virtual cassette imaging site and imaging direction, a plurality of human body simulated images which simulate a virtual cassette imaging subject who is positioned relative to a virtual cassette medical imaging device, and are generated on the basis of a human model configured from three-dimensional computer graphics data; and a virtual cassette machine learning model is trained by using a plurality of training data comprising the generated virtual cassette simulated images and the correct data for the virtual cassette combinations.
