ACR | American College of Radiology |
AEIRA | Association of Educators in Imaging and Radiologic Sciences |
AHA | American Hospital Association |
ARDMS | American Registry of Diagnostic Medical Sonographers |
ARRT | Licensing--American Registry of Radiologic Technologists |
ASRT | Curriculum--American Society of Radiologic Technologists |
JRCERT | Accreditation-Joint Review Committee on Education in Radiologic Technology |
NCRP | National Council on Radiation Protection and Measurements |
OSHA | Occupational Safety and Health Administration |
RSNA | Radiological Society of North America |
SI | International System of Units |
Anode | charged electrode in the X-ray tube. Source of X-ray photons |
PBL | Positive Beam Limitation-field of light is automatically collimated down to the designated IR size. |
Bucky | Device used to make the grid reciprocate back and forth to make lead lines invisible on radiograph |
Cathode | charged electrode in the X-ray tube. Cathode filament is the source of electrons |
contrast | differences in densities on a radiograph. |
density | degree of blackness/darkness on a radiograph |
Focal Spot | located on the anode target. Cathode beam is focused here. The origin of X-rays. Controls detail. |
Grid | device which improves/enhances film quality and contrast. Helps clear scatter. Made up of lead lines which absorb scatter radiation |
HIS | Hospital Information System |
IP | Imaging Plate. Made of photostimuable phosphor (PSP) |
Intensifying Screens | located in casette. Can be single/double. Screen gives off light when struck by xrays/photons as % of light forms the exposure on the film. |
kVp | Quality. Kilovoltage peak. Controls the energy of the X-ray beam. The higher energy; higher quality. |
GR | Grid Ratio- higher GR the better for scatter clean up. Scatter looks like fog. |
Matrix | Soft copy image comprised of rows and columns of data |
PACS | Picture Archiving and Communications Systems |
RIS | Radiology Information System-used for billing |
Voxel | volume element, 3D pixel. |
Window Level | Brightness. Mid point density in a digital image. |
Window Width | adjusts contrast of a digital image. |
