Method of obtaining a tomographic image

摘要

A method of obtaining a tomographic image of part of an animal or a part of an animal including a human being or a part of a human being by using radioactive radiation is disclosed. The animal is at least partly placed into a measuring cavity having an axial axis. The measuring cavity being at least partially surrounded by a cavity wall which is provided with a plurality of pinholes, and behind the pin holes (as viewed from the measuring cavity or lumen) detection means are placed. A radioactive radiation from a radioactive isotope administered to the animal is detected in a position-related manner by the detection means and data obtained with the detection means are used for the generation of the tomographic image.
