Standard Practice for Determining Image Unsharpness and Basic Spatial Resolution in Radiography and Radioscopy

active, Most Current
Publication Date: 1 February 2022
Status: active
Page Count: 8
ICS Code (Optics and optical measurements in general): 17.180.01
scope:

This practice covers the design and basic use of a gauge used to determine the image unsharpness and the basic spatial resolution of film radiographs or of digital images taken with CR imaging plates, digital detector arrays, or radioscopic systems.

This practice is applicable to radiographic and radioscopic imaging systems utilizing X-ray and gamma ray radiation sources.

Units-The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

The gauge described can be used effectively with tube voltages up to 600 kV.

When using source voltages in the megavolt range, the results may not be completely satisfactory. The gauge may be used in the MV range, preferably for characterization of detectors without object.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
