Rad 101 Ch 8 Radiographic and
Fluoroscopic Equipment fully solved A+
rated
anode - correct answer ✔✔positive electrode of the x-ray tube
bucky mechanism - correct answer ✔✔grid that is an integral part of the x-ray table, located below the
table top and above a cassette tray; decreases the amount of scatter radiation reaching the image
receptor, which increases contrast; moves during exposure so that no grid lines appear on the image
cassette - correct answer ✔✔light-proof holder for 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 - correct answer ✔✔negative electrode of the x-ray tube
collimator - correct answer ✔✔diaphragm or system of diaphragms made of an absorbing material;
designed to define the dimensions and direction of a beam of radiation; device consisting of 4 rectilinear
radiopaque blades that are adjustable to control x-ray field size and shape
digital imaging - correct answer ✔✔acquisition of static images in an electronic fashion; conversion of
images to a digital format for image manipulation, enhancement, storage and networking
diode - correct answer ✔✔electrical component that possess polarity with a negative and positive
terminal
flat panel detector - correct answer ✔✔type of digital detector employing amorphous silicon or
selenium detector material, bonded with thin-film transistor technology for digital image creation and
amplification
, fluoroscope - correct answer ✔✔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
fluoroscopy - correct answer ✔✔examination by means of fluoroscope employing image intensification
goniometer - correct answer ✔✔angulation scale incorporated into the x-ray tubehead assembly to
indicate the degree of x-ray tube angle relative to the image receptor
hard copy - correct answer ✔✔radiographic image created on a polyester film medium
latent image - correct answer ✔✔invisible image created after x-ray exposure and before image
processing
longitudinal - correct answer ✔✔lengthwise; along the long axis
overhead tubecrane - correct answer ✔✔mechanical support for suspending the x-ray tube and
collimator assembly from the ceiling of the radiographic room
picture archival and communication system (PACS) - correct answer ✔✔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) - correct answer ✔✔automatic collimation- form of x-ray beam
collimation of field size that ensures the x-ray exposure field is no larger than the receptor size
detects the size of the image receptor and automatically reduces/increases beam size to correspond
postprocessing - correct answer ✔✔manipulation of medical images after they have been acquired
through x-ray exposure, to improve image quality and diagnostic yield
pyrex glass - correct answer ✔✔special type of glass that can withstand very high temperatures from the
x-ray tube anode
