Abstract

In medicine, a change in the documentation of rendered services and therapeutic results is currently taking place. Previously, simple standards were sufficed to document the quality and effectiveness of a treatment. In the case of surgical and dermatological treatments, the therapy was initiated according to diagnosis and indication and ended with a histological examination and confirmation of the diagnosis by the pathologist. Newer therapeutic methods, e.g., laser surgery, conservatively treat and remove pathological changes in the skin surface, without the possibility of sending a specimen to the pathologist. Diagnostics must therefore be capable of documenting the dynamic effects of the treatment in the initial phase and subsequent development of the disease. To make it possible to achieve this goal, fast and exactly working 3D invivo measurement methods are necessary, which permit a direct access to the three-dimensionality of the human skin surface. With the digital fringe projection based on micromirror projectors from the Texas Instruments company and the PRIMOS technology, respectively, a new optical 3D measurement method is presented, which makes it possible to measure human skin surfaces fast and very accurately both in the micro and macro-ranges and to document treatment results objectively.
