Term
Definition
show A feature of modern x-ray systems that enables simultaneous vertical movement of an upright image receptor and overhead x-ray tube  
🗑
show Positive electrode of the x-ray tube  
🗑
show Grid that is an integral part of the x-ray table, located below the tabletop and above a cassette receptor tray. It decreases the amount of scatter radiation reaching the image receptor, which improves image quality increases contrast  
🗑
show Lightproof holder for the image receptor. In computed radiography, the cassette holds the reusable photostimulable phosphor imaging plate; in conventional film-screen radiography, the cassette contains intensifying screens and a sheet of film  
🗑
Cathode   show
🗑
Collimator   show
🗑
show Acquisition of static images in an electronic fashion; conversion of images to a digital format for image manipulation, enhancement, storage, and networking  
🗑
Diode   show
🗑
DR Panel   show
🗑
show Type of digital detector employing amorphous silicon or selenium material bonded with thin-film transistor technology for digital image creation and amplification  
🗑
show Device used for dynamic radiographic examinations; usually consists of an x-ray tube situated underneath the x-ray table and an electronic image detector situated over the x-ray table  
🗑
show Examination by means of the fluoroscope, employing image intensification  
🗑
Goniometer   show
🗑
show Radiographic image created on a polyester film medium  
🗑
show Invisible image created after x-ray exposure and before image processing  
🗑
Longitudinal   show
🗑
show A perpendicular relationship between the x-ray beam central ray (CR) and image receptor  
🗑
Overhead Tube Crane   show
🗑
show Computer network for the transmission, viewing, and archival storage of medical images; often integrated into a larger hospital information system (HIS) and radiology information system (RIS)  
🗑
Positive Beam Limitation (PBL)   show
🗑
Postprocessing   show
🗑
show Special type of glass that can withstand very high temperatures from the x-ray tube anode  
🗑
show A receptor of x-radiation that intercepts the primary beam and prevents exposure if not interlocked with the central ray of the x-ray beam  
🗑
show Describes a material that easily transmits x-ray energy with very little absorption  
🗑
show Images in which dynamic patient motion is visualized instantly as fluoroscopic imaging is occurring  
🗑
Remnant Radiation   show
🗑
Soft Copy   show
🗑
show Equipment that permits the acquisition of static images during a dynamic fluoroscopic examination; images are recorded using film or are acquired digitally and stored electronically  
🗑
show Electrical wire connection between a digital detector and the x-ray generator and computer  
🗑
Transverse   show
🗑
Trendelenburg Tilt   show
🗑
show Pivoting the tube at the point where it is attached to its support  
🗑
show Perpendicular to the plane of the horizon  
🗑
show Device that produces x-rays  
🗑
show Equipment consisting of the x-ray tube, collimator, and operator controls; permits manipulation of the x-ray tube in many directions for proper positioning  
🗑
