Title:
MEDICAL IMAGE PROCESSING DEVICE AND MEDICAL IMAGE PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/281965
Kind Code:
A1
Abstract:
A control unit of this medical image processing device executes an image acquisition step (S1), an inclination reduction step (S2), and a medical data acquisition step (S4). In the image acquisition step, the control unit acquires a tomographic image including a layer of tissue. In the inclination reduction step, the control unit executes, on the tomographic image, an inclination reduction process of reducing inclination of the layer with respect to a principal direction. In the medical data acquisition step, the control unit acquires medical data by inputting an inclination-reduced image, which is the tomographic image having been subjected to the inclination reduction process in the inclination reduction step, into a mathematical model that has been trained by a machine learning algorithm and that carries out a process with respect to an input image to output medical data.
