A alternate in kV through 15% is equal to a alternate in mAs via... - ANS-a component of 2
a whole history of patient entails: - ANS-whilst it took place, mechanism of damage, things that
make it better or worse, and verifying an appropriate part and side as what has been recorded
Absorbed dose measured in: - ANS-rad/Gray
absorbed radiation - ANS-takes place when incoming photons eject internal shell electrons
which speedy loses energy
absorbed radiation= - ANS-radiopaque
brought filtration - ANS-filtration added to the a part of the tube to absorb low power photons
and decrease affected person dose
Adults probably to reduce in 1 year dose of: - ANS-10% of zero.Five Sv deep dose
AEC (computerized publicity manage) - ANS-gadget used to offer consistent quantity of
radiation to the IR terminating exposure while the proper quantity of radiation is reached.
Radiation travels thru the affected person then air cells prior to the IR
age fog - ANS-a generalized discount of fine due to exploration of film. Can additionally occur to
processed movie because there will usually be same processing chemical substances ultimate
Agfa: Direct - ANS-1mR=2.5; Factor of 2 =alternate of zero.3
Log median valve (1gm)
aliasing - ANS-an artifact which appears as two superimposed photos slightly off from every
other because of low sampling frequency
analog signal - ANS-go out radiation stimulates crystals and traps electrons. Released by using
blue laser in form of mild-wave bureaucracy and collected and sent to ADC
analog to virtual conversion (ADC) - ANS-Digitizing the picture (scanning, Sampling,
quantization
Analog to Digital Converter (ADC) - ANS-converts photograph to virtual signal that the pc knows
allowing the picture to be methods and saved
Angle and tilt - ANS-allows the tube to perspective along the lengthy axis of the desk and goals
toward the wall rather than the tab
annual dose restrict for embryo/fetal occupational exposure: - ANS-zero.Five mSv/month; 5mSv
complete being pregnant
annual dose limit for occupational publicity lens of the eyes: - ANS-150 mSv
annual dose restriction for Skin, Hands, and Feet occupational publicity: - ANS-500 mSv
annual dose restrict for the public: Frequency/continuous exposure= - ANS-1mSv
annual dose restriction for the general public: infrequent publicity= - ANS-5mSv
annual dose restriction for the general public: lens of the eyes= - ANS-15mSv
annual dose restrict for the general public: pores and skin, hand and ft= - ANS-50mSv
Annual Occupational dose: - ANS-50 mSv
Annual Occupational Effective Dose Limit for occupational publicity: - ANS-50mSv but has been
recommended to be diminished to 20mSv
Annual Public dose: - ANS-5 mSv
, anode - ANS-side of the tube that may be a undoubtedly charged target for electrons to convert
to x-rays; composed of molybdenum copper and tungsten; consists of a goal, stator, and rotor
anodes may be - ANS-desk bound or rotating (rotating disperse heat and reduce put on)
Any attitude among the IR, part or beam will cause... - ANS-form distortion (ie. Elongation and
foreshortening)
Any space among the part and the IR will purpose... - ANS-magnification. Increased SID will
decrease magnification
are virtual IR's more touchy than film? - ANS-yes
as kVp increases... - ANS-beam penetrability will increase
as little as reasionably conceivable - ANS-Radiographer obligation to reduce the radiation dose
to the affected person, themselves, and others thru techniques, defensive, time and distance
atomic mass - ANS-backside right range on the element
atomic mass - ANS-the sum of general number of neutrons and protons within the atom
atomic range - ANS-pinnacle right range at the element
atoms charge - ANS-Positive nucleus with terrible cloud around it. Overall neutral
computerized publicity control (AEC) - ANS-gadget to offer consistency of radiation dose to the
IR through controlling publicity time. In order for use efficiently the part need to be properly
focused with accurate air cells selected and right collimation
backing - ANS-made of hard fabric to offer tension to the cassette
base - ANS-reduces and conducts away any static electricity
beam limit - ANS-whilst elevated in digital it's going to lower exposure and growth assessment;
in film screen it will decrease exposure and density and boom contrast
Bremsstrahlung radiation - ANS-takes place whilst projectile electron completely avoids
tungsten orbital electrons and travel close to the nucleus, electrostatic forces purpose the
electron to slowdown and alternate path; lost electricity is released as x-ray photon; most x-ray
interactions are bremsstrahlung; 100% bremsstrahlung under 70 kVp, 85% bremsstrahlung
above 70 kVp
cardinal regulations - ANS-Time, distance, protective
Carestream/Kodak: Direct - ANS-1mR=2000: Factor of two =trade of three hundred
Exposure indicator/index (EI)
cassette - ANS-tool to keep x-ray film and intensifying display
cassette - ANS-serves as movie holder to offer mild tight inflexible structure; protects film;
homes intensifying display (commonly one in front and one in returned)
cathode - ANS-aspect of the tube that produces the electrons and forces them towards the
anode; negatively charged
ceiling mount - ANS-additionally known as overhead tube meeting. Most widely used and
maximum versatile. Two rails are established to the ceiling with the tube droop and permits the
maximum flexibility for pass table examinations
changes in kVp do now not have as an awful lot of an impact on evaluation in virtual
photographs so... - ANS-it can be accelerated more allowing decrease mAs
Check replenishment weekly inside... - ANS-5%
Check solutions quarterly- developer and glued pH have to be... - ANS-developer 10-11.Five pH
fixer four-.45pH
