description A scintillation scanner having an information density indicator system for counting the number of electrical pulses representative of radiation activity which occur during a predetermined increment of movement of a detection probe and dividing the number of counted pulses by a selected line spacing distance in order to provide direct indication of information density. The information density indicator system utilizes counting circuitry for counting the number of pulses which occur during a predetermined interval of time and scaling circuitry for scaling the number of pulses by a factor which is dependent upon a selected distance of line spacing. The system also incorporates storage circuitry and digital-to-analog conversion circuitry for storing and processing the signals for application to an indicator device.
