- 3. A digital imaging system that uses a detector array in place of the Bucky assembly; the imaging-forming radiation is captured and transferred to a computer from the detector array for almost instant viewing at the control panel.
- 4. The range of exposure intensities that an image receptor can respond to and acquire image data.
- 6. A device that absorbs x-rays and creates electrical charges in proportion to the x-ray exposure received.
- 8. The visible radiographic image on the exposed detector after processing.
- 12. A sturdy, light-proof container for film. Also a sturdy protective container for the photostimulable phosphor plate in computed radiography.
- 14. The emission of light from the screen when stimulated by radiation.
- 15. Provides a numeric value indicating the level of radiation exposure to the digital image receptor.
- 17. An electronic system that allows patients’ electronic records (medical information and imaging studies) to be accessed from various workstations within or outside of a facility.
- 19. The invisible image that exists on the image receptor before it has been processed.
- 21. The process by which washing works; exposes the film to water that contains less thiosulfate than the film.
- 22. Electronic components layered onto a glass substrate that include the readout, charge collector, and light-sensitive elements.
- 23. A device used to sense the light released from the photostimulable phosphor plate during scanning.
- 24. The release of energy from trapped electrons by a laser during the scanning of a photostimulable phosphor plate.
- 25. A material that absorbs x-ray energy and emits visible light in response.
- 26. A digital imaging system that uses a cassette, a photostimulable phosphor plate, a plate reader, and a computer workstation to acquire and display a digital image.
- 27. A measure of the ability of the system to preserve signal contrast (display the contrast of anatomic objects varying in size), and the value will be between 0 (no difference in brightness levels) and 1.0 (maximum difference in brightness levels).
- 28. The range of exposure values to the image that will produce an acceptable range of densities for diagnostic purposes.
Down
- 1. A common computer language that allows different systems of a picture archiving and communication system to communicate with each other.
- 2. A light-sensitive semiconducting device that generates an electrical charge when stimulated by light and stores this charge in a capacitor.
- 5. A scintillator device made up of a crystalline silicon matrix.
- 7. A measurement of the efficiency of an image receptor in converting the x-ray exposure it receives to a quality radiographic image.
- 9. A plate made up of several layers that stores x-ray energy as a latent image for cassette-based digital systems.
- 10. The physical component consisting of Diffusion: The process by which washing works; it exposes the film to water that contains less thiosulfate than the film.l for display on a computer workstation.
- 11. Archiving and Communication System (PACS)- A secure network for transmitting and exchange of patient images and data, display (viewing and workstations), and storage (archive server) sy reader- A device equipped with a drive system and optical system that converts the stored image on a photostimulable phosphor plate to an electronic signal for display on a computer workstation.
- 13. A measurement of exposure in air, followed by a computation to estimate absorbed dose to the patient.
- 16. Established values within histogram models that determine what part of the data set should be incorporated into the displayed image.
- 18. Number of bits that determines the amount of precision in digitizing the analog signal, and therefore the number of shades of gray that can be displayed in the image.
- 20. A process in which a computer analyzes the histogram using processing algorithms and compares it to a preestablished histogram specific to the anatomic part being imaged.
