If I set the setparameters function in the simpleitk package to (1, 0, 0, 0, 0, 0), how many degrees does the image rotate? thank you.

I expect it would rotate 1 radian, which is approximately 57.2958°.

Thank you.

By the way, I would like to ask, I rotate the image on the z-axis, set the parameter to 1, and then calculate the mutual information value between this image and the fixed image, and get the value a. By calculating the mutual information between the graph before rotation and the fixed image, the value B is obtained. Why is a close to B? I’m confused.
