Nuclear medicine comes increasingly technologically advancing, an example of this is the range
of camera SPECT (single photon emission computed tomography) device that performs the
anatomic and physicological study of organs, wich are increasingly improved. Its precursor was
the known by thyroid mapping. Through this mapping could see the functioning of parts of the
gland. Later, Benedict Cassem created the linear cintilograph, wich produced macroscopic
anatomical images expressing also the molecular dimension funtion. In 1957, Hal Anger
scintillation camera created. The image was recorded on photographic film, put in the decade of
70, David e Kuhl created the above-mentioned equipement. The first device consisted of two
scintillation detectors. The current equipment models have more than one head thus, capture
greater radiation area, making examination time is decreased. The most used equipment
currently are from GE, Philips and siemens and their most advanced models os SPECT are
respectively: infinia Hawkye 4, brightview XCT, Symbia intevo. Some of these studies, show
that the evolution of the image capture equipment, was of great importance in nuclear medicine,
wich currently counts with modern equipment. And it was concluded that all models of SPECT
presented highly sophisticated technologied have, thus, important acquisitions for the nuclear
medicine clinics.
