*The test methods are based on the use of test patterns. This standard does not apply to x-y (analogue) recording systems used in nuclear medicine. This standard is a part of a series of Particular Publications (standards and technical reports) which give methods of tests for the constancy of properties of diagnostic imaging systems as described in IEC 1223-1 (see clause 2). 1.2 Object* This part of IEC 1223 describes a method to check, in terms of functional parameters, the constancy of the quality of images produced by hard copy cameras in order to ensure that the required conditions for producing consistent hard copies are maintained after the calibration and adjustment have been carried out. The aims of the method are:
With regard to the measurements, reference is made to methods described in related publications, which for practical reasons should be carried out prior to the application of the method described in this standard (see clause 2).
