I have a CT image (512*512*446)
DICOM info is unfer below
- Pixel spacing: 0.4648, 0.4648
- Spacing Between Slices: 0.8
- SliceThickness: 1
I use squeeze changing tha axial CT to sagittal view, while image distort in the sagittal plane (left).
It should be as same as what I look the sagittal view on Radiant (right).
You can see the vertebral body is elongated in the image.
Is it because of the difference between pixel spacing and slice thickness ?
Or is there any method to avoid this?

The images are not isotropic and hence it is distorted.
J = imresize(I,[446*1/0.4648, 512])

Instead of resizing the image, you can also use image directly to set the XData and YData scales separately. It is a bit more work on your part, but you don't run the risk of introducing artifacts in the resizing.
