It is performed using a fiberoptic [1] instrument called a flexible fiberoptic nasopharyngoscope, [2] that is inserted through the nose in order to examine both it, and the back of the throat. [3] It is typically used to identify a variety of conditions including nasal septal deviation , polyps , and edema , [ 4 ] and the causes of conditions ...

The main disadvantage of the ADCPs is the loss of data close to the boundary. This mechanism, often referred to as a sidelobe interference, covers 6–12% of the water column and, for instruments looking up toward the surface, the loss of velocity information close to the surface is a real disadvantage. Cost is also a concern but is normally ...
Other methods relying on instruments include the use of a colorimetric end-tidal carbon dioxide detector, a self-inflating esophageal bulb, or an esophageal detection device. [35] The distal tip of a properly positioned tracheal tube will be located in the mid-trachea, roughly 2 cm (1 in) above the bifurcation of the carina; this can be ...
Comparison microscope is used to analyze the matching of the microscopic impressions found on the surface of bullets and casings. When a firearm or a bullet or cartridge case are recovered from a crime scene , forensic examiners compare the ballistic fingerprint of the recovered bullet or cartridge case with the ballistic fingerprint of a ...
In the top-right image, the cystoscope has been bent within the bladder to look back on itself. The bottom two images show an inflamed urethra. If a patient has a stone lodged higher in the urinary tract, the physician may use a much finer calibre scope called a ureteroscope through the bladder and up into the ureter. (The ureter is the tube ...
Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
