"Picture-in-picture" endoscopic images in the microscope
Abstract:
The authors describe a new piece of equipment that enables simultaneous monitoring of the endoscopic image and unilateral microscopic image; that is, "picture-in-picture" images for endoscope-assisted microsurgery. The system is simple and purely optical, consisting of light-weight semi-rigid fibers and a special adapter incorporated in the microscope. Throughout the initial neurosurgical procedures in which it was tested, the system proved particularly useful for inspecting the facial nerve behind the acoustic neurinoma and for observing the contact between arteries and the facial nerve during decompressive procedures for hemifacial spasm.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
