[Method of assessing the information content of gamma chambers in studying mobile organs].
In investigating mobile organs, such as the liver, lungs, spleen and heart their image on the scintigram is blurred which deteriorates the function of the modulation transmission (FMT). An analytical expression for calculating the FMT in investigating the mobile organs was deduced. Examples of the FMT impairement in investigating the liver and heart are cited. Concrete recommendations for increasing the informativeness of investigation with a gamma-chamber are given.
