When the measurement phase requested by the system is
different than the phase of the cursor position, the following
message is displayed:
"Display ######### image"
######### represents the phase opposite of the one just
completed.
Auto determination of systole/diastole is only available on a
frozen image. It cannot be done on a recalled image or one
from an external video input.
If Manual is selected, each measurement has a 's' or 'd' at the
end of it's name. The system will not determine the phase or
ask the operator to make that determination.
Doppler measurement menus (D-AV, D-MV, D-PV and D-TV)
each have a selection called Auto Trace. When the user
selects Auto Trace, the start point and end point of a
measurement is set. After the end point is set, the system
traces the waveform and automatically calculates the values as
follows:
Ao Auto Trace: (Set start and end points for FVI-AV)
Calculates: FVI-AV, MaxPG, MeanPG, Ejection Time, AccT,
DecT, PFV and Mean-V
MV Auto Trace: (Set start and end points for FVI)
Calculates: FVI, MaxPG, MeanPG, Pressure Half Time, MV
Area, AccT, DecT, PFV, Mean-V and Ejection
Time
PV Auto Trace: (Set start and end points for FVI-PV)
Calculates: FVI-PV, MaxPG, MeanPG, AccT, DecT, PFV,
Mean-V and Ejection Time
TV Auto Trace: (Set start and end points for FVI)
Calculates: FVI, MaxPG, MeanPG, Pressure Half Time,
AccT, DecT, PFV, Mean-V and Ejection Time
