2.  Developed by Hal Anger at Berkeley in
1957 therefore also called Anger camera
 Gamma rays emitted by radio
pharmaceutical (e.g. technetium 99m (Tc-
99m) that have been introduced into the
body as tracers.
 The position of the source of the
radioactivity can be plotted and displayed
on a monitor or photographic film.
 Radiopharmaceuticals , radioisotopes ,
radio nuclei , radioactive materials enter in
body through GIT tract.
 It starts decaying after completion Half-life
WHAT IS GAMMA CAMERA
It is a device used to detect that is used to
detect or receive gamma radiations
Other names
Scintillation camera
Anger camera
Crystallographic camera

3. Pathway of
radiopharmaceutical
It is the time period it completes when
organ of interest complete absorption
Gamma camera is also ionizing
technique but the source of radiation
is body not the system
HALF LIFE
Medicine is solid form via (GIT) and
it deposit for specific half life
After half life nucleus become half
and break into alpha , Beta , gamma
radiations
Radiopharmaceutical starts decaying after
completing half life.

4. Similarity between MRI and Gamma
Gives physiological and anatomical detail
Cross sectional 3d images
Both involves nucleus
Difference between MRI and Gamma
Detectors are different
Ionizing and non ionizing
Applications
Use to locate cancerous tumor
To locate abnormal functioning of organs
To locate bone fracture
Lungs scan
Myocardial perfusion
Bone scan
Summary (basic working)
Radioisotope injected in patient which
emits gamma radiations . The Gamma
camera scans the radiation area and
create and image
Gamma camera scan of skull of cancer patient
