1 Seivert equals a hundred - ANS-rem
12:1 - ANS-general purpose, chest
sixteen:1 - ANS-high kVp radiology
5:1 - 6:1 - ANS-Grid cassettes, cell radiography
eight:1 - ANS-trendy cause
ninety nine% of the strength of the electrons hanging the goal is converted into? - ANS-Heat
A cassette containing movie receives the x-ray beam. The movie now consists of a latent image
and turns into seen after being processed in a? - ANS-Dark room
A layer of lead foil can be observed within the back of a cassette to prevent - ANS-backscatter
A special mechanism that prevents tube movement at a particular vicinity is? - ANS-Detent
AEC - ANS-Requires accurate positioning, require use of bucky, affords constant radiographic
density
An digital plate receives the x-ray beam and produces and digital sign that is despatched at
once to a laptop for processing and digital photograph formation? - ANS-Direct/Digital
An elevated OID will result in? - ANS-Increased penumbra and decreased image clarity
Annual dose limit for an occupationally uncovered radiation worker - ANS-5 rem
Annual dose restriction for the majority - ANS-0.1 rem
Artifacts - ANS-Quantum mottle, moire pattern, light spots, phantom or ghost pix, scratches or
tears, lines, fogging.
As display speed will increase, the quantity of x-rays needed to produce density will? -
ANS-Decrease
Attenuation - ANS-A decrease within the beneficial beam as it's far partially absorbed by a body
component
Average annual dose from background radiation - ANS-zero.360
Below 70 kVp, there aren't any - ANS-characterisitcs
Bremmstrahlung - ANS-has no electrons and hits tough
Bremmstrahlung radiation - ANS-One of forms of x-rays. Brems is created whilst an electron
enters the tungsten anode of the x-ray tube and misses the tungsten electrons and gets near
the nucleus. The electron unexpectedly slows down and deviates. The loss of strength creates
an x-ray photon.
Bucky grid - ANS-Moves, you may push out and pull in and has a ratio of 12:1 - sixteen:1.
Central Nervous System syndrome - ANS-5000+ rads complete frame dose, reason of dying:
increased intracranial strain, vasculitis, meningitis.
Characteristic radiation - ANS-One of two styles of x-rays. This is created while an electron
enters the tungsten anode of the x-ray tube and knocks the k shell out of orbit. This interaction
creates an x-ray photon.
Coherent - ANS-Below 10 kVp
Coherent scattering - ANS-Thompson Scatter.. Interactio takes region at low energy ranges,
below 10 kVp.
, Compton - ANS-Collides with OUTER orbital electron and scatters. 40-one hundred twenty five
kVp
Cumulative dose limit for fifty yr vintage radiation worker - ANS-50 rem
Developer temp is vital and should be - ANS-ninety five tiers F
Digital receptors offer a huge variety of publicity latitude when compared to - ANS-film display
structures
Directly proportional to the amount of the x-ray beam? - ANS-mAs
Do dark room partitions want to be painted black? - ANS-No!!
Does electromagnetic radiation have mass? - ANS-No
Dose in RAD accelerated by way of a exceptional issue gives the dose in.. - ANS-rem
Electromagnetic strength - ANS-x-ray
Fluroscopy is? - ANS-The transferring x-ray and pt swallows barium sulfate
Gastrointestinal syndrome - ANS-Death due to excessive damage to intestinal lining, 1000-1500
rad complete frame dose
Gray equals one hundred - ANS-RAD
Grid cuttoff - ANS-Excessive absorption, didnt make it d/t cutoff
Grid Frequency - ANS-Number of lead strips per inch
Grid Radius - ANS-Distance to which grid strains are centered and additionally the SID at which
grid have to be used.
Grid Ratio - ANS-Height of lead strips divided by way of distance among strips
Hematologic syndrome - ANS-death due to infection, hemorrhage and two hundred-2000 rads
entire frame dose
Higher kVp have to be used for what sort of frame parts? - ANS-Larger or greater dense frame
parts
Higher kVp might do what to the penetration? - ANS-Increase penetration
Higher pace screens are fabricated from? - ANS-Thicker phosphor layer and an increase of
crystal length
Higher the grid means - ANS-the extra dose given
If kVp is elevated, the amount of scatter will - ANS-growth
If the kVp is increased, the quantity of photo density will - ANS-increase
If the kVp is accelerated, the photo assessment will - ANS-decrease
If the kVp is elevated, the affected person and operator dose will - ANS-increase
In CR, the phosphor plate can be scanned with the aid of a? - ANS-Laser
Increasing kVp, field size and pt or element thickness will bring about - ANS-Increased scatter
fog
Increasing the SID will bring about? - ANS-A lower patient dose
Information arranged in a chain of columns or rows? - ANS-Matrix
Initial or Primary Radiation - ANS-Bremmstrahlung or Characteristic
Interacting aka Secondary Radiation - ANS-Photoelectric, compton, coherent
Ion - ANS-when a impartial atom gains or loses an electron
Ionization can bring about what type of damage? - ANS-Biological Damage
kVp - ANS-fine, the PUSH. The quantity of kVp does NOT change the penetrating ability
Law of Bergonie and Tribondeau - ANS-Radiosensitivity of cells is at once proportional to their
reproductive pastime and inversely proportional to their diploma of differentiation. Thus the
