I mean , can we create more training patients datasets from given datasets?

Apart from the usual affine and pixel-wise transformations, you might try elastic and diffeomorphic data augmentations which are suited for medical images. I found a description of these techniques in a nature article which I can't seem to find now. In terms of generating artificial data, you could look into GANs.

roi_crop, rotation, flip are useful,
scale, elastic deformation do not work
