"the cover. the picture on the cover is a section through the chest of a living human subject made by the technique of reconstruction from projections (see "image reconstruction from projections," page 56). in that technique a series of x-ray exposures made from different angles around the body are combined by computer to present a cross-sectional picture on the screen of a cathode-ray tube. in the picture on the cover the chest is seen as though it were viewed from above the patient's head. the dark spaces to the left and right are the lungs. the large red area in the middle is the heart. the white areas are bone; below the center is the spinal column, and around the lungs are sections through the ribs. in general the tomato red areas are muscular tissue and the lavender areas are fatty tissue. the branched areas in the lungs are blood vessels and bronchi. the picture was made (by the delta scanner built by ohio-nuclear, inc.) in the course of a study that was conducted by ralph j. alfidi, m.d. of the cleveland clinic foundation." in ct, technicare developed and sold
