A fluorescence diagnosis system has a viewing system at least one light source and a camera system. The at least one light source can be operated in three modes, a first generating white light, a second with a first fluorescence excitation light of a first excitation wavelength and a third in which a second fluorescence excitation light of a second excitation wavelength is generated producing a fluorescence image in the NIR range. The camera system is sensitive at least in the visible and the NIR range. The system further comprises an image processing system for converting the fluorescence image in the NIR range into a visible image.

A light system for medical photodynamic applications comprises an incoherent light source emitting a light with a power and a light guide which has a distal end and an entrance interface. The entrance interface and the light source have a position relative to one another and are able to be positioned relative to one another. The light system further comprises a luminous power meter for measuring a luminous power emitted at the distal end of the light guide, a motorized positioning unit for positioning the entrance interface and the light source relative to one another, and a control unit which controls the positioning unit as a function of the luminous power measured by the luminous power meter.

The invention relates to a virtual OP simulator () for training for minimal-invasive operations, in particular for endourological interventions, having a simulation calculator unit (), at least one instrument (), at least one instrument input unit () for picking up the instrument (), with the instrument input unit () allowing and recording movement of the instrument () in a predetermined number of degrees of freedom, and a force feedback unit () which is associated with the instrument input unit () and applies variable forces to the instrument () directly or indirectly via the instrument input unit (). A monitoring control unit () is provided, which is connected to the simulation computer unit () and to the instrument input unit (), with the monitoring control unit () having a first interface () which provides communication of parameters between the monitoring control unit () and the simulation computer unit () at a speed in the region of the video framing rate, and having a second interface () which provides communication of parameters with the instrument input unit () at a speed which is higher than, in particular a multiple of, the video framing rate, and with the instrument input unit () allowing at least four degrees of freedom, detecting movements of the instrument () within these degrees of freedom, supplying corresponding signals to the monitoring control unit () and receiving signals for the force feedback unit (), at least some of which are generated by the simulation computer unit ().
