3 Terms and definitions
The following terms and definitions as defined in GB/T 34365 apply to this document.
3.1
Computer tomography computed tomography; computerizedtomography; CT
A detection method for reconstructing a physical feature distribution map of an object from a projection data.
3.2
Spatial resolution spatial resolvingpower
Spatial resolution
A measure of the ability of the CT system to identify and distinguish the geometric details of an object being measured.
Note. Spatial resolution/spatial resolution is one of the main technical indicators of CT systems. Spatial resolution is usually in mm, and spatial resolution is usually
Lp/mm is the unit.
3.3
Density resolution densityresolvingpower
Density resolution densityresolution
Under certain conditions, the CT system recognizes the ability of a specified size region to differ from the surrounding region in an object.
Note. Density resolution/density resolution is one of the main technical indicators of CT systems. Density resolution is usually in mm. Density resolution is usually
