Abstract: A medical image processing method, an X-ray diagnostic apparatus, and a method of generating a learned model includes receiving first X-ray image data, inputting the first X-ray image data to a trained model, outputting, from the trained model, an X-ray image having an image quality higher than an image quality of the first X-ray image data. The learned model was trained using contrastive learning using second X-ray image data as input data, third X-ray image data and fourth X-ray image data as label data, the third X-ray image data being negative label data having worse image quality than the second X-ray image data, and the fourth image data being positive label data having better image quality than the second X-ray image data.
