Abstract: An endoscopic instrument capable of being optically coupled to a video monitor adapted with a prismatic screen is disclosed. The instrument includes a working channel of 0.35 mm and a biopsy instrument having a substantially tubular end. The prismatic screen is mounted between a flat image and a viewer. Additional optical elements may be provided to enlarge a viewed image. A light hood may be provided to reduce glare and other effects of ambient light. Coating the screen with an anti-reflective coating may provide further protection from ambient light. Restructuring the image into smaller image elements provides image quality for a video image or the like. An aspherical lens may be used to minimize or remove distortion of the image perceived by a viewer to the side, above or below the center viewing axis of the screen.

Abstract: A method of extracting biopsy cells from a breast uses an endoscopic instrument having a distal end that is substantially needle like, a working channel, a light source and a lens. The instrument can be coupled to an apparatus for viewing an image including depth of field viewing. The instrument is inserted into a nipple of a breast and liquid is ejected from the distal end. Reverse pressure is applied so that the liquid and biopsy cells are retrieved into the instrument. The cells are then extracted from the breast.

Abstract: A screen is disclosed for viewing depth of field images. The screen includes a prismatic screen mounted between a flat image and a viewer. Additional optical elements may be provided to enlarge a viewed image. A light hood may be provided to reduce glare and other effects of ambient light. Coating the screen with an anti-reflective coating may provide further protection from ambient light. Restructuring the image into smaller image elements provides image quality for a video image or the like. An aspherical lens may be used to minimize or remove distortion of the image perceived by a viewer to the side, above or below the center viewing axis of the screen. The present invention may find particular application in computer monitor systems, medical and obstetric imaging such as sonograms, musculo-skeletal imaging, vascular imaging, angiograms, angioplasty, dental probes, catheter probes, ear probes, endoscopy, laparoscopy, pelviscopy and arthroscopy.

Abstract: A screen is disclosed for viewing depth of field images. The screen includes a curved prismatic screen mounted between a flat image and a viewer. A light hood may be provided to reduce glare and other effects of ambient light. Further protection from ambient light may be provided by coating the screen with an anti-reflective coating.
