With the increasing use of imaging technologies during surgeries and autopsies, new control methods for computer systems are required to maintain sterility. Gesture controlled systems seem to be promising, since they allow for a touch-free control of computer systems. In a previous publication we presented a system which allows the control of the open source Picture Archiving and Communication System (PACS) OsiriX by means of gesture and voice commands. In order to overcome the limitations of this system, we developed a plug-in for OsiriX that allows for gesture control of the DICOM viewer of OsiriX with finger gestures. Â© 2012 Elsevier Ltd.
