Auto Calculation
Resume Set auto calculation on and off.
Auto Calculation parameters
Resume Set PS, ED, MD, PV, TAMAX, PPG, MPG, HR, VTI, RI, DT, AT, S/D, PI, D/S auto
calculation parameters.
Automatic calculation and of parameters automatic calculation
Resume The spectrum Doppler waveform is recorded and the parameters are calculated. The
results of the automatic spectrum calculation will be displayed in the measurement
window in real time.
Influence
The heart rate value obtained by automatic spectrum calculation may have some
deviation. If you want to obtain accurate heart rate value, please choose manual
measurement to obtain.
Dynamic range
Resume The amount of information that represents the conversion of echo intensity into
grayscale gradient spectrum.
Effect Corresponding to the adjustable contrast range of the image, the larger the dynamic
range, the richer the level of image display and more information, but the noise will
also increase.
Influence This feature is valid for real-time, frozen, and movie playback images.
Audio
Resume Controls and adjusts the output audio size generated by spectrum Doppler.
Effect Combined with the volume signal, we can judge the blood flow state and nature more
effectively.
Scanning speed
Resume Controls the refresh speed of PW mode.
Effect More detailed observations can be obtained, such as changing the scanning speed to
detect anomalies in the period.
Acoustical Power
Resume
Adjust the power of the probe to emit ultrasound.
Effect
The louder power increases the overall brightness of the image evenly, and the
detection depth also increases.
Influence
In clinical application, proper sound power should be selected according to the actual
situation and ALARA sound power principle.
