CT - ANSWER the introduction of ______ started radiology's transition
into digital
reusable detector - ANSWER Digital radiography imaging systems
replace traditional film with a
computed radiography - ANSWER image data are digitized and
immediately displayed on a monitor or recorded on film
digital radiography - ANSWER any method of X-ray image formation
that uses a computer to store and manipulate data.
Photostimulable phosphor (PSP) - ANSWER The phosphor layer of the
imaging plate (IP) is composed of barium fluorohalide crystals doped
with europium
create the image - ANSWER once the PSP is exposed, the cassette is
taken to the reader to process the plate and
two-step process - ANSWER computed radiography is a
digital radiography - ANSWER the detector and reader that are a
permanent part of the table or wall unit, a cassette is not needed
direct conversion detectors - ANSWER Directly converts the radiation
to electrical charges
indirect conversion detectors - ANSWER use a two part process
involving a scintillator and a photodetector
scintillator - ANSWER converts incoming x-ray photons to light
, DICOM - ANSWER Protocol for transmission between imaging devices
digital image - ANSWER An image that has been converted into
numerical values for transmission or processing
analog signals - ANSWER the electronic devices that produce
radiographic images by design produce
digital analog signals - ANSWER a series of voltage fluctuations on a
continuous waveform with infinite values between upper and lower
values
binary machine language - ANSWER Language required to form a
digital image
analog-to-digital conversion - ANSWER A process of converting
continuous information into discrete data; some information is typically
lost.
sampling - ANSWER the analog voltage values are measured at a
chosen sampling frequency on the analog waveform
quantification - ANSWER the process of turning the sampled piece of
analog data into a discrete analog value
binary digit - ANSWER after sampling and quantification, the analog
values are converted into a
0 - ANSWER off in the binary system
1 - ANSWER on in the binary system
bit - ANSWER binary digit
byte - ANSWER a group of 8 bits
in terms of the number of values displayed per image - ANSWER how
are computerized digital images described
