VueScan is a computer program for image scanning, especially of photographs, including negatives. [4] It supports optical character recognition (OCR) of text documents. [ 5 ] [ 6 ] The software can be downloaded and used free of charge, but adds a watermark on scans until a license is purchased.
Scan-Optics was one of the technology groups enabling the transition from paper to digital. Scan-Optics developed the image dissector tube and made it commercially available, pioneered an alphanumeric handwriting recognition system, and introduced key data entry integrated with optical character recognition via a direct computer-to-computer ...
Drishti (from Sanskrit दृष्टि dr̥ṣţi, meaning "vision" or "insight") is a multi-platform, open-source volume-exploration and presentation tool. [1] Written for visualizing tomography data, electron-microscopy data and the like, it aims to ease understanding of data sets and to assist with conveying that understanding to the research community or to lay persons.
Cone-beam spiral computed tomography (CT) is a medical imaging technology that has impacted healthcare since its development in the early 1990s. [1] [2] This technology offers advancements over traditional fan-beam CT, including faster scanning speed, higher image quality, and the ability to generate true three-dimensional volumes, even with contrast-enhancement.
These 64-bit HDRi color files and 32-bit HDRi greyscale files contain additional 16-bit infrared RAW data besides the 48-bit color RAW data and 16-bit greyscale RAW data respectively. [10] [11] Therefore, a scanner with an infrared channel available to the software is necessary. This RAW format can keep any readable image information for later ...
In conventional CT machines, an X-ray tube and detector are physically rotated behind a circular shroud (see the image above right). An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of ...
This technology is the fastest generation of CT scanner to date. Third-generation spiral CT designs, especially those with 64 detector rows, 3×360°/sec rotation speeds, and designed for cardiac imaging, are largely replacing the EBT design from a commercial and medical perspective. However, electron beam CT still offers sweep speeds of ...
Industrial computed tomography (CT) scanning is any computer-aided tomographic process, usually X-ray computed tomography, that uses irradiation to produce three-dimensional internal and external representations of a scanned object. Industrial CT scanning has been used in many areas of industry for internal inspection of components.
