摘要： A surgical microscope system for use in a medical procedure. The surgical microscope system is controlled in a first mode of operation corresponding to a phase of the medical procedure and defining at least one setting for adjusting a set of adjustable optics. While in the first mode of operation, the surgical microscope system automatically determines, from a captured image, an indication that a second mode of operation is relevant. The mode of operation is switched to the second mode of operation.

摘要： In a first embodiment, there is no monitoring, and instead light is delivered according to a predetermined ‘recipe.’ In a second embodiment, the instrumentation provides a means for making the reflectance measurements during therapy without requiring the brief interruption. This device may therefore allow more accurate measurement of treatment-induced changes to the reflectance measurement. In a third embodiment, an adjustable aperture is used to constrict the area of a treatment beam.
