The term describing the planar region or the image slice selection region.

The not measured distance between the slices. A lower gap can introduce more noise into adjoining slices.

The spatial distribution of sensitivity of the imaging process in the direction perpendicular to the plane of the slice. When the profile deviates appreciably from rectangular, the slice thickness alone may not provide an adequate description.

Relates to the addition of phase encoding steps for 3D volumetric imaging.

Exclusive excitation of spins in one slice performed by the coincident combination of a gradient magnetic field and a narrow bandwidth or slice selective RF pulse at a specific Larmor frequency.
