---|---|---|---|---|---|
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
🗑
