Abstract
An instrument for indicating anomalies in human tissue comprises first and second light emitters. The first light emitter comprises a tungsten filament which transilluminates the tissue and visually indicates any anomalies therein. The second light emitter emits a light of higher intensity than the light from the first emitter. The second emitter is actuated while the tissue is being transilluminated by the first light emitter to make an exposure on infrared sensitive film located at an opposite side of the tissue.
