Photographie numérique médicale et dentaire. Le choix d’un appareil photo simple et économique

Introduction. Digital photography is more and more important in our everyday medical practice. Patient data, medico-legal proof, remote diagnosis, forums, and medical publications are some of the applications of digital photography in medical and dental fields. A lot of small, light, and cheap cameras are on the market. The main issue is to obtain good, reproducible, cheap, and easy-to-shoot pictures. Technical note. Every medical situation, portrait in esthetic surgery, skin photography in dermatology, X-ray pictures or intra-oral pictures, for example, has its own requirements. For these reasons, we have tried to find an "ideal" compact digital camera. The Sony DSC-T90 (and its T900 counterpart with a wider screen) seems a good choice. Its small size makes it usable in every situation and its price is low. An external light source and a free photo software (XnView (R)) can be useful complementary tools. The main adjustments and expected results are discussed. (C) 2010 Elsevier Masson SAS. All rights reserved.
