  2. Fluoroscopy - Wikipedia

    en.wikipedia.org/wiki/Fluoroscopy

    Image Intensifiers are still being used to this day (2023) with many new models still using II (Image Intensifier) as its method of acquiring the image which is still popular due to lower cost compared to Flat Panel Detectors and there have been many debates on whether II or Flat Detector is more sensitive to X-Ray, which results in lower X-Ray ...

    en.wikipedia.org/wiki/Johnson's_criteria

    The minimum required resolution according to Johnson's criteria are expressed in terms of line pairs of image resolution across a target, in terms of several tasks: [3] Detection, an object is present (1.0 +/− 0.25 line pairs) Orientation, symmetrical, asymmetric, horizontal, or vertical (1.4 +/− 0.35 line pairs)

  4. Image intensifier - Wikipedia

    en.wikipedia.org/wiki/Image_intensifier

    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 ...

  5. X-ray image intensifier - Wikipedia

    en.wikipedia.org/wiki/X-ray_image_intensifier

    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.

  6. Digital subtraction angiography - Wikipedia

    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.

  7. Fluorescence imaging - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_imaging

    DNA Sequencing: Sanger Sequencing is a common form of nucleic acid detection that may use fluorescently labeled ddNTPs to image fluorescence peaks; Fluorescence image guided surgery: is a medical imaging approach that fluorescently labels a mass to aid in navigation. For example, indocyanine green can be used to detect lymph nodes in cancer ...

  8. Microchannel plate detector - Wikipedia

    en.wikipedia.org/wiki/Microchannel_plate_detector

    The mass-market application of microchannel plates is in image intensifier tubes of night vision goggles, which amplify visible and invisible light to make dark surroundings visible to the human eye. MCP detectors are often employed in instrumentation for physical research, and they can be found in devices such as electron and mass spectrometers.

  9. Photocathode - Wikipedia

    As such it tends to function as a form of 'electric film' and shared many characteristics of photography. It was therefore the key element in opto-electronic devices, such as TV camera tubes like the orthicon and vidicon, and in image tubes such as intensifiers, converters, and dissectors.
