N2 - To make recommendations for the selection of digital imaging equipment and its use in the typical orthopaedic surgery practice, we investigated four digital cameras with maximal resolution ranging from 1.3-3.34 megapixels. We took images of a plain radiograph, a magnetic resonance image, a hand model, and a minifragment plate with all four digital cameras and a 35-mm film camera. Several variables were evaluated to determine their effect on image quality, including adjusting maximal camera resolution, using a flash, using a camera stand, and using a macromode. Images were graded on a 3-point scale on the computer desktop and as 5 × 7 inch prints by two blinded observers. A maximal camera resolution of 2.1 megapixels was required to make photograph-quality 5 × 7 inch prints of all subjects imaged. No difference in print quality was seen between images taken in the highest quality JPEG format and the uncompressed TIFF format. A macromode with closest focal length less than 5 inches was needed for imaging small subjects. The 1.3-megapixel camera was comparable with the higher resolution cameras for imaging radiographic studies and when viewing color images on the computer desktop.
