Physics Mode 6 Flashcards
1
Q
What has the worst temporal resolution
A
Color doppler
2
Q
Color frame time calculation
A
Color frame time = 13 micros/cm x depth/acoustic line x acoustic line/color packet x color packet/display line
3
Q
Total frame time calculation
A
Total frame = color frame + 2D frame
4
Q
Flow direction in color doppler
A
Angle of flow always between steered beam and head of flow (direction of flow)
5
Q
Pro and con of color angio doppler
A
Power Doppler Pro: 1) more sensitivity to low flow 2) better filling in small vessels 3) less angle dependent
Con:
1) no flow direction
2) less apparent variation in flow patterns
