These slender plastic rulers contain alternate 1 cm sections of Co-57 (10 µCi) and cold material. They are placed on the area to be measured, and the camera base line and window are adjusted for Co-57. To imprint the film, ten counts are sufficient. The ruler’s image appears on the scintiphoto, allowing definition of anatomical location and/or organ size by counting the number of visible “hot” and “cold” 1 cm areas.
