The SPECT emission phantom is an acrylic cylinder of 200 mm outside diameter and an active length of 190 mm. It simulates the head and can be supplied with a circular cover to insert point and line sources. The sources are introduced via three thin wall acrylic tubes of 7 mm diameter that are placed in the center and at distances of 45 mm and 90 mm from the center. If the tubes are not in use, they can be filled with scattering material.
