For improvement of the techinique of roentgenographic mass survey for the detection of lung cancer, we devised a new equipment of fluorographic tomography using Cancer mirror camera. Excellent tomograms were obtained by the equipment. It seems adequate to take three films for individual subject on mass survey, a P-A film, left lateral, and tomogram.<BR>The tomogram was taken with the following exposure conditions. The focal plane was set at the center of the chest breadth and the moving angle of the X-ray tube was 20 degree. Overall exposure dose in three projections was about 0.6 R. Approximately 30 persons could be examined in an hour by this method.
