[en] The dose of patient radiation and image quality are primary concerns in the conduct of nuclear medicine procedures. Accurate interpretation of nuclear medicine image data depends on understanding the image patterns and quantitative results. This also applies to both quality control testing and clinical studies. Such understanding comes by learning from different examples, in addition to having in-depth knowledge of the underlying and how to achieve optimal results

[en] A comprehensive set of acceptance tests is the basis for an effective quality control program. Acceptance tests conform to the manufacturer’s specifications but should also include evaluation of certain parameters not specified by the vendor but that can seriously affect image quality. Once a camera is accepted, initial quality control tests serve as a benchmark for future measurements. The quality control of nuclear medicine instruments is that the quality control should be undertaken as an integral part of the routine work of the nuclear medicine department and should be performed by the departmental staff themselves. At the same time, reference tests should be carried out to provide data against which its subsequent performance can be assessed by routine testing that is performed on a weekly, monthly, quarterly and annual basis. Various procedures are now employed in the acquisition and analysis of quality control tests, but National Electrical Manufacturers' techniques and protocols are generally recognised to give a description, accurate measurement, and reporting of camera performance characteristics. There is a certain amount of time that can be spent on system quality control each day. In order to maintain control over the important parameter, a QC program's main objective should be to do so. a) Most susceptible to system performance changes b) most likely to have an influence on clinical studies as daily uniformity test (Extrinsic or Intrinsic)
