What metal is used as the filament in a radiograph machine?
What is tungsten
100
this restricts the size of the beam
What is collumnator
100
Quantity of electrons comes from
What is mA
100
Contrast is primarily controlled by
kVp
100
Too dark but adequate penetration
decrease mA
200
This is the varible piece. . . can either be stationary or fixed
What is an anode
200
1. Prepare the tanks 2. Unload cassette
3. Load film on hanger 4. Develop the film
5. Rinse the film 6. Fix the film
7. Wash the film 8. Final rinse
9. Dry the film
What is 9 steps to manual processing
200
Electron speed is determined by
kVp
200
Too light = underexposed
more kVp or mAs
200
Too dark with too much penetration
decrease kVp
300
This is the area where the electrons are generated from
What is a cathode
300
name all three ways to recover silver
What is metallic replacement, electrolyte recovery, chemical precipitation
300
The degree of blackness on an x-ray is
Density
300
Too dark = overexposed
less kVp or mAs
300
conditions other than your technique chart that affect radiographic quality are
Pleural fluid/cardiomegaly/ascites, Obesity/heavy muscling, Neonatal canine/feline , Procedures with contrast
400
this is another word for the "halo effect"
What is penumbra
400
a radiographic identification marker must contain
hosp. name, hosp. address, date taken, patient info
400
Density is primarily controlled by
mA
400
Too light but adequate penetration
mAs increased
400
what are the 3 qualities of a good darkroom
clean/organized/lightproof, separate from the radiographic suite, climate control
500
The maximum energy available at a particular setting
What is kVp
500
patient info includes. . . .
patient name, owner last name, patient signalment
500
The density difference between two areas on the same radiograph is
contrast
500
Too light with inadequate penetration
kVp increase
500
how long should you stand in a darkroom to check for light leaks?
