Slice Thickness and Interval - Video Lesson

This lesson is about the reconstruction slice thickness and slice interval. This might at first sound a little confusing, but the acquisition slice thickness may or may not be the same as the reconstruction slice thickness. The acquisition thickness is really just the thickness of the detector rose, but the reconstruction slice thickness is the thickness of the images that we see on the screen. For example, a technologist can set a scan to acquire the data with one millimeter slices. So that would be one millimeter detector rows. But here she could also choose to reconstruct the same data to be displayed with four millimeter slices. So the acquisition thickness would be one millimeter, but the images would be displayed with a reconstruction slice thickness of four millimeters. In this case, the scanner would just average to get
