The invention relates to an arrangement for a plane source for gamma cameras in which the radiation is brought about using a radioactive homogeneous liquid. When collecting correction matrices for gamma cameras, the minimum possible variation in the thickness of the plane source is desirable. This has been achieved by using a liquid container for radioactive solutions with a plane reflective bottom which is adjusted horizontally by means of a vertical laser beam, the laser beam, after adjustment, being reflected to the starting point of the laser beam. <IMAGE> |
