  2. Rectilinear scanner - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_scanner

    capture emission from radiopharmaceuticals in nuclear medicine. A rectilinear scanner is an imaging device, used to capture emission from radiopharmaceuticals in nuclear medicine. The image is created by physically moving a radiation detector over the surface of a radioactive patient. It has become obsolete in medical imaging, largely replaced ...

  3. Contact image sensor - Wikipedia

    en.wikipedia.org/wiki/Contact_image_sensor

    Contact image sensors ( CIS) are image sensors used in flatbed scanners almost in direct contact with the object to be scanned. Charge-coupled devices (CCDs), the other kind of sensor often used in scanners, use mirrors to bounce light to a stationary sensor. Scanners using CISs are much smaller than ones that use CCDs, use typically a tenth as ...

    en.wikipedia.org/wiki/Optical_mark_recognition

    The first mark sense scanner was the IBM 805 Test Scoring Machine; this read marks by sensing the electrical conductivity of graphite pencil lead using pairs of wire brushes that scanned the page. In the 1930s, Richard Warren at IBM experimented with optical mark sense systems for test scoring, as documented in US Patents 2,150,256 (filed in ...

  7. High Capacity Color Barcode - Wikipedia

    en.wikipedia.org/wiki/High_Capacity_Color_Barcode

    High Capacity Color Barcode. High Capacity Color Barcode ( HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes. [1] Data density is increased by using a palette of 4 or 8 colors for the triangles ...

    en.wikipedia.org/wiki/Optical_character_recognition

    Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...

  9. Barcode technology in healthcare - Wikipedia

    Barcode technology in healthcare. Barcode technology in healthcare is the use of optical machine-readable representation of data in a hospital or healthcare setting. Dating back to the 1970s, there has been a continual effort among healthcare settings to adopt barcode technology. [1] In the early 2000s, published reports began to illustrate ...

  10. Barcode - Wikipedia

    en.wikipedia.org/wiki/Barcode

    A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which ...

  11. A total of 15 learning-disabled and 15 skilled readers viewed three groups of nonsense pictures (unnamed, name-nonassociated, and name-associated), then recalled them later. Results suggested learning disabled children's reading difficulties are due to an inability to activate a semantic representation that interconnects visual and verbal codes.
