Abstract

A review console displaying digital radiographs should automatically display the chest images in proper orientation to save radiologists' time. To accomplish this feat, the authors have developed a simple, rapid algorithm that can be implemented in hardware. Linear regression is used on two orthogonal profiles to determine the top of the image. The edge of the heart is found to make sure the image is not displayed as a mirror image. The algorithm was 90.4 percent successful on 115 chest images.
