The field of nuclear medicine is a classic example of a medical discipline that has
embraced and utilized the concepts developed in the physical sciences.Conceived as a
‘‘joint venture’’ between the clinician and the physical scientist,it has evolved into an
interdisciplinary field of activity with its own body of knowledge and techniques.In the
process,the domain of nuclear medicine has grown to include studies pertaining to:
1.The creation and proper utilization of radioactive tracers (or radiopharmaceu-
ticals) that can be safely administered into the body
2.The design and application of nuclear instrumentation devices and systems to
detect and display the activity of these radioactive elements
3.The determination of the relationship between the activity of the radioactive
tracer and specific physiological processes
To better understand this radiation imaging modality,it is necessary to discuss
radioactivity,its detection,and the instruments available to monitor the activity of
radioactive materials.
