摘要： Methods and systems are provided to enable multiple imaging modalities with a single camera head. The camera head may include a two chip or a three chip system capable of measuring different wavelengths of light to generate different images. The light source in the system can adjust the output spectra, by using a plurality of illuminants and filters, and measurements from different light channels on one or more images sensors can be used to generate white light images, fluorescence image, perfusion images, fluorescein images, and the like.

摘要： A medical scope device such as an endoscope is produced using a cast aluminum process including a molten casting aluminum alloy including a maximum of 0.2-0.3% Si and at least 5% Zn. The process includes providing an investment casting mold, casting the aluminum alloy in the mold to create a component and removing the mold from the component, post-machining the component to meet a desired specification, and after post-machining the component, performing surface finishing, such as centrifugal barrel finishing (CBF) sufficient to remove impurities on casting surfaces by 2-3 mils, then coating the component with a micro-crystalline aluminum anodic coating of at least 0.5 mil thickness. A medical scope and product-by-process is also provided employing such techniques.

摘要： A fluorescence imaging system is configured to generate a video image onto a display. The system includes a light source for emitting infrared light and white light, an infrared image sensor for capturing infrared image data, and a white light image sensor for capturing white light image data. Data processing hardware performs operations that include filtering the infrared image data with a first digital finite impulse response (FIR) filter configured to produce a magnitude response of zero at a horizontal Nyquist frequency and a vertical Nyquist frequency. The operations also include filtering the infrared image data with a second digital FIR filter configured with a phase response to spatially align the white light image data with the infrared image data. The operations also include combining the white light image data and the infrared image data into combined image data and transmitting the combined image data to the display.

摘要： Improved fluoresced imaging (FI) endoscope devices and systems are provided to enhance use of endoscopes with FI and visible light capabilities. An endoscope device is provided for endoscopy imaging in a white light and a fluoresced light mode. A chromatic adjustment assembly, typically implemented with prisms, compensates for a chromatic focal difference between the white light image and the fluoresced light image caused by the dispersive properties of the optical materials or optical design employed in the construction of the optical channel. The assembly is placed optically between the most proximal rod lens of the endoscope and the focusing optics, typically at an internal telecentric image space, to improve the chromatic correction. The prism assembly directs incoming light with different spectral content along separate paths which compensate for chromatic aberration.

摘要： A counting unit is provided for use in an electrical device. The counting unit is configured to count a thermal event such as an autoclave cleaning operation when the electrical device is not electrically powered. In one aspect, the counting unit includes a rotary member and an actuator, the actuator is configured to change shape from a first configuration to a second configuration when subjected to a predetermined temperature, wherein in the second configuration, the actuator engages the rotary member so as to rotate the rotary member. In another aspect, the counting unit includes a plunger, a drive and a heat resistant arm configured to release the plunger during a thermal event and retain the plunger when the electrical device is cooled down.
