reorienting 3D image stack

We have a set of xray images im(x,y)

They are a 3D set in height im(x,y,h) through hte plane of an object.

The object is on a xray platfrom and the planes are between the source and detector.

I can make a movie going through the planes without a problelm.

However, I want to be able to see it as if i was looking from the side of the image set rather than the top but I keep getting errors

figure, imshow(image2(50,:,:))

Error using images.internal.imageDisplayValidateParams>validateCData (line 118)

Multi-plane image inputs must be RGB images of size MxNx3.

path = ['C:\Users\\OneDrive - \Desktop\alabama concepts\image sets\3D images\ImageData-Reconstructed slices DICOM\mini1\mini1\0\']

    writeVideo(y,im2);
end

Try adding 'squeeze' to you code.

The image array you are passing to imshow is m x n x p. Even though m=1, because it is 3D, imshow is assuming it is rgb image data, which can only have a size of 3 in the 3rd dimension.
