Scope and object The object of this part of IEC 61675 is to specify test methods for describing the characteristics of GAMMA CAMERA BASED WHOLEBODY IMAGING SYSTEMS. As these systems are based on Anger type GAMMA CAMERAS this part of IEC 61675 should be read in conjuction with IEC 60789. Two additional tests@ scanning speed constancy@ and system SPATIAL RESOLUTION without scatter@ shall be performed. Measurement of system uniformity for wholebody imaging systems is possible but difficult to perform because of the requirement for large and uniform sources. Most of the potential problems that could affect uniformity will also affect the system resolution@ and therefore such a uniformity test is not included in this standard. The test methods specified in this part of IEC 61675 have been selected to reflect as much as possible the clinical use of GAMMA CAMERA BASED WHOLEBODY IMAGING SYSTEMS. It is intended that the test methods be carried out by manufacturers@ thereby enabling them to describe the characteristics of GAMMA CAMERA BASED WHOLEBODY IMAGING SYSTEMS.
