Cone Beam CT: Slice thickness

Cone beam CT units have a range of slice thicknesses available.  Most units fall between 0.1 mm to 0.4 mm slice thickness.  There are units with smaller slice thickness available, however I am focusing on the 0.1 to 0.4 mm range for this post.  The first thing to understand is […]

Digital radiography: Spatial resolution

This weeks topic on digital radiography is spatial resolution.  Spatial resolution is the capacity for distinguishing fine detail in an image.  The term used to identify this is line pairs per millimeter (lp/mm).  The higher the spatial resolution, the greater the capacity for distinguishing fine detail.  An average observer is […]
