6. Using Modes
This chapter provides information and instructions for using modes when performing an ultrasound study.
NOTE
Advanced imaging capabilities may vary depending on the selected preset and status of paid sub-
scription. Please visit
for the latest details on which preset has ac-
cess to which modes.
Using Color Doppler Mode or Power Doppler Mode
When using Color Doppler or Power Doppler, you can:
• Adjust the size and position of the ROI.
• Adjust the Gain and Depth.
• Adjust the Scale (also known as Pulse Repetition Frequency (PRF)) to optimize for high or low flow by touching
the High/Low control at the bottom of the screen
The ROI is displayed on the image. To move the ROI, tap and drag the box.To adjust the angle and size, use the
arrows provided.
Color gain and depth controls are available during Doppler imaging.
Using M-Mode
M-Mode display includes speed controls (Fast or Slow), the M-Mode line, B-Mode image, and a move point to move
the M-Mode line.
When using M-Mode, you can:
• Adjust the radial scan line by tapping and dragging the move point:
• Adjust the sweep speed of the M-Mode display by touching the Fast/Slow control in the middle of the screen
• Adjust the Depth and Gain
• Perform time, distance, and heart rate measurements on the display
Using Spectral Pulsed-Wave Doppler Mode
Spectral Pulsed-Wave Doppler (Pulsed Doppler) is a quantitative mode that graphically displays blood flow velocity
measurements over time.
When using Pulsed Doppler, you can:
• View and adjust the position of the sample volume by holding and dragging the gate.
• View and adjust the angle correction by holding and dragging the white caliper dot.
• Switch between live Pulsed Doppler mode and live B-mode by touching the Start Spectrum/Update B-mode but-
ton.
