The introduction of flat-panel detectors allows for the replacement of the image intensifier in fluoroscope design. Flat-panel detectors offer increased sensitivity to X-rays, so have the potential to reduce patient radiation dose. Temporal resolution is also improved over image intensifiers, reducing motion blurring.
An image intensifier or image intensifier tube is a vacuum tube device for increasing the intensity of available light in an optical system to allow use under low-light conditions, such as at night, to facilitate visual imaging of low-light processes, such as fluorescence of materials in X-rays or gamma rays (X-ray image intensifier), or for conversion of non-visible light sources, such as ...
Fluorescence-lifetime imaging yields images with the intensity of each pixel determined by , which allows one to view contrast between materials with different fluorescence decay rates (even if those materials fluoresce at exactly the same wavelength), and also produces images which show changes in other decay pathways, such as in FRET imaging.
An X-ray image intensifier (XRII) is an image intensifier that converts X-rays into visible light at higher intensity than the more traditional fluorescent screens can. Such intensifiers are used in X-ray imaging systems (such as fluoroscopes ) to allow low-intensity X-rays to be converted to a conveniently bright visible light output.
Flat-panel detectors are a class of solid-state x-ray digital radiography devices similar in principle to the image sensors used in digital photography and video. They are used in both projectional radiography and as an alternative to x-ray image intensifiers (IIs) in fluoroscopy equipment.
While he still says he will quickly solve it, he has largely dropped that line, and he is now due to take office in less than two weeks. "I hope to have six months. No, I would think, I hope long ...
The mask image is simply an image of the same area before the contrast is administered. The radiological equipment used to capture this is usually an X-ray image intensifier, which then keeps producing images of the same area at a set rate (1 to 7.5 frames per second). Each subsequent image gets the original "mask" image subtracted out.
