I have two images of the same matrix size (512x512) but different pixel spacing. One image has a pixel spacing of 0.7 and the other 0.4. How do I get the two images to have the same pixel spacing and still maintain the matrix size of both images.

You could extract the image pixel values into new arrays. This would preserve the size of the images and ignore pixel spacing (or consider them equal if you will). I would suggest using the impixel function.

I don't want to extract the pixels from the image, my aim is to make these images the same both in matrix size and pixel spacing so I can register them. At the moment my registration is failing because although my images are the same in size the spacing between my matrices are different.
