SLOT Advance (Slot Radiography option enhanced for SONIALVISION G4) provides images with long fields of view, such as for full spine or full leg images, just by a very simple workflow, while also offering high accuracy images with minimal X-ray dose. SLOT Advance acquires a series of only accurate images of a few centimeters central slit as the. The chest digital radiography system is a digital charge-coupled device (CCD) chest imaging unit that uses slot-scan technology. A contrast-detail test object was used in combination with a phantom that simulates the primary and scatter transmission for the lungs and mediastinum.

Digital slot-scan charge-coupled device radiography.

The U.S. Department of Energy's Office of Scientific and Technical Information. Our purpose in this study was to evaluate the fundamental image quality characteristics of a new slot-scan digital chest radiography system (ThoraScan, Delft Imaging Systems/Nucletron, Veenendaal, The Netherlands). The linearity of the system was measured over a wide exposure range at 90, 117, and 140 kVp with added Al filtration. System uniformity and reproducibility were established with an. Digital equalization radiography Digital equalization radiography Geluk, Ronald J. 1999-05-28 00:00:00 ABSTRACT A beam equalization system has been developed for a recently introduced digital slot scanner. Its equalization range is tailored to the dynamic range of digital camera's. Applied beam profiles are made available to be included in the image file for associated image processing.

Two broad classes of digital radiography equipment are available for veterinarians: cassette-based, or computed, radiography (CR) and direct (capture) radiography (DR).1,2. This article focuses on primary capture devices instead of secondary capture devices such as image digitizers (scanners) and digital cameras. Purpose To evaluate the diagnostic performance of full-field slot-scan charge-coupled device (CCD)-based digital radiography in the detection of simulated chest diseases in clinical conditions versus that of two screen-film techniques: advanced multiple beam equalization radiography (AMBER) and Bucky radiography.

The authors present a novel technique for large-field digital mammography. The instrument uses a mosaic of electronic digital imaging [charge coupled device (CCD)] arrays, novel area scanning, and a radiation exposure and scatter reducing mechanism. The imaging arrays are mounted on a carrier platform in a checker-board pattern mosaic. To fill in the gaps between array-active areas the.

Slot scanners have shown significantly reduced scatter fraction compared with anti-scatter grids (Samei et al. 2004; Liu et al. 2008) and have shown some improved detection of simulated nodules and interstitial lung pathology in phantom testing (Kroft et al. 2004, 2005) but there is no information on use in clinical pediatric chest imaging.

Digital Slot Scan Mammography Using CCDs - NASA/ADS.

A desirable mammography imaging system should offer high spatial resolution, high sensitivity, a wide dynamic range and a means of limiting detected x-ray scatter. Significant scatter reduction can be obtained with a slot scan acquisition format with minimal attenuation of the primary beam. A potential receptor for digital mammography is comprised of a x-ray screen optically coupled directly. Purpose: To evaluate the diagnostic performance of full-field slot-scan charge-coupled device (CCD)-based digital radiography in the detection of simulated chest diseases in clinical conditions versus that of two screen-film techniques: advanced multiple beam equalization radiography (AMBER) and Bucky radiography. Materials and methods: Simulated nodules.

Digital radiography: The bottom line comparison of CR and DR.

A novel solid state detector has been developed for digital radiography. It is based on an assembly of CCD chips operated in TDI mode. The X-ray detection is achieved by a CsI scintillator layer which features a needle structure. It combines an excellent resolution with a high absorption efficiency. The detector is able to operate in 2 modes: a standard resolution mode and a high resolution. Digital radiography starts being introduced in the early 1990s corresponding to the establishment of first generation of picture archiving and communication system (PACS). This technology is steadily increased until now with quality at least equal to if not better than that conventional technique.... Drawing illustrates a slot-scan CCD-based. 1.
