Settings Flashcards
What does the gain setting do
Alters brightness
What does time gain compensation do
Corrects for attenuation
How does time gain compensation correct for attenuation
Alters the gain/ volume for different depths to make it equal all the way through
What corrections of attenuation do you want to make with your time gain compensation settings
Suppress shallow and amplify deep
How are the controls for time gain compensation separated
Near and far (there’s a separate control for each depth)
Patient prep for ultrasound
- Shave transducer contact area
- Coupling gel to eliminate air interface
What are the 4 transducer manipulations?
- Tilting
- Rotating
- Alignment
- Pressure
When manipulating the transducer, what does pressure do?
Changes depth
When manipulating the transducer, what does alignment do
Moving from point to point with the transducer in the same direction
When manipulating the transducer, what is rotating
Changing axis 90 degrees
