calculation the dimension of one pixel in a coronal plane in a CT

Dear colleague,

I am writing a medical (research) paper in which i would have to
calculate the dimension of one pixel in a coronal plane in a CT scan.

I think that when the slice thickness of the ct scan is 0,625 mm and
the pixel spacing is 0,4 mm, the dimension of one pixel in a coronal
plane is 0,625 mm x 0,4 mm (the slice thickess x the width of the
pixel that is given from the pixel spacing). Is it right?

If yes, how will i support that the dimension of one pixel in coronal
plane is the slice thickness x the width of the pixel, based on the

I am looking forward to hearing news from you.

Actually the slice thickness does not necessarily have to correspond to the pixel height in the coronal MPR reconstruction from axial slices.
Pixel height will be equal to the distance between axial slices. Usually this value is equal to the slice thickness but sometimes the slices can be overlapping.
