Mesh terms iodine isotopes photography / instrumentation*. The performance of a gamma camera system is defined by the sharpness and detail of the images it produces, the efficiency with which it detects incident radiation, its ability to measure the energy of the incident γ rays (to minimize scatter), and the counting rate it can handle without significant dead time losses..

When gamma rays pass through the human body, they ionize the tissue. Allows for imaging of physiological function rather than simply anatomy. Gamma cameras or scintillation cameras are pieces of apparatus which allow radiologists to carry out 'scintigraphy scans', tests which provide detailed diagnoses about the functioning of the thyroid, the heart, the lungs and many other parts of the.

Solid gamma cameras offer many potential benefits over conventional nai crystal imaging. Images of the thyroid gland obtained using gamma cameras present numerous advantages over those obtained by scanners, in particular for the study of cold nodules, the thyroglossal duct or ectopic thyroids, and generally in every case where iodine uptake is very low. Solid state comes in two main.
