ABSTRACT:
A gamma camera is provide, that can be used to measure the coefficient of attenuation of the gamma radiation in a body studied by means of a gamma camera normally made to study the effects of gamma radiation emitted by markers injected into the body. To this end, the collimator is removed from this gamma camera, and it is replaced by a ring and by an arm to which there is fixed a chamber designed to contain a radioactive point source external to the body. It is shown that it is thus possible to obtain images in transmission very swiftly. These images are useful for the correction of normal emission images.
