Selecting a different imaging mode can be performed by tapping 
and selecting the corresponding mode. Note that not all modes may be available depending on the scanner, selected application, and software licenses availability. See the Basic Controls guide for the key B mode manipulations.
Supported modes include:
- B-Mode (B)
- M-Mode (M)
- Spatial Compounding (SC)
- Color Flow Imaging (CFI)
- Power Doppler Imaging (PDI)
- Pulsed Wave Doppler (PW)
- Needle Enhancement (NE)
- Strain Elastography (E)
M-Mode
Turn on M-Mode through the M option within the modes menu. M-Mode can be used to visualize structures moving based on cardiac cycles and also has a place in lung imaging. M-Mode imaging is largely based on the B-Mode settings already in place, however, some additional controls do exist.
- To adjust the gate position, or imaging line, used to capture spectral data, drag the dotted line horizontally across the image.
- To adjust zoom of the spectrum, vertically pinch the spectral display, or double tap to engage a 200% zoom, and double tap once more to go back to 100%. After adjusting the zoom, the gate can be repositioned by sliding up and down on the spectral display.
Spatial Compounding
Turn on Spatial Compounding through the SC option within the modes menu. Spatial compounding can add a smoother feel to the image and also add more detail by compounding imaging frames acquired at different angles. Some applications start in spatial compounding mode by default, but can be turned off by going back to B from the modes menu. Spatial compounding does not offer additional controls from B mode.

Color & Power Doppler
Turn on Color or Power Doppler through the CFI or PDI options within the modes menu. There are multiple controls that can be used to adjust Doppler imaging.
For a short video tutorial, visit our Clarius Classroom using the Color Doppler mode.
In CFI or PDI modes, sliding horizontally across the image will no longer adjust the B or grayscale brightness, but rather the Color Gain. When adjusting the gain, the percentage will be displayed temporarily at the top of the image.
The following region of interest (ROI) controls are available.
- To change the ROI position, press the center of the ROI and drag.
- To resize the ROI, press the
icon, and drag. - To change the Doppler steer for obtaining the best flow profile, press the
icon, and drag. Note that steering of the ROI is only available on linear scanners (L7, L15, and L20).

The Color Map can also be used to adjust various parameters. The Color Map represents the direction and general velocity of the Doppler flow. The color showing towards the top of the map correlates to flow coming towards the scanner surface, and the color showing towards the bottom of the map correlates to flow going away from the scanner surface. The minimum and maximum velocities are shown at the top and bottom of the Color Map.
- To invert the Color Map, tap on the map once. This will alternate the red and blue colors that display the direction of the Doppler flow. Note that PDI mode does not support inversion of the colors, as Power Doppler does not display directional information.
- To change the viewable velocity range (in cm/s, but also correlates to PRF or Pulse Repetition Frequency), slide up and down on the Color Map. While changing the velocity range, the value will be shown temporarily at the top of the image, as well as the correlating wall filter frequency. Note that the PDI mode, the velocity range is not displayed, but rather the PRF.

Pulsed Wave Doppler
Pulse Wave Doppler is only available with an Advanced Feature Package or as a part of Membership
Turn on Pulsed Wave Doppler through the PW option within the modes menu. There are multiple controls that can be used to adjust Doppler imaging. For a short video tutorial, visit our Clarius Classroom using the Pulsed Wave Doppler mode.
The spectral display offers multiple manipulations to control various parameters.
- To change the velocity range (in cm/s, but also correlates to PRF or Pulse Repetition Frequency), slide up and down on the velocity scale on the right side of the spectrum. While changing the velocity range, the PRF value will be shown temporarily at the top of the image, as well as the correlating wall filter frequency.
- To change the spectral brightness, slide up and down on the brightness icon on the side of the spectrum. While adjusting, the value will be shown temporarily at the top of the image.
- To change the baseline to allow proper positioning of the spectral display, slide up and down on the spectrum itself.
- To invert the spectrum, double tap anywhere on the spectral display.
The Doppler gate on the B-mode image also offers various control manipulations.
- To change the position of the gate (should be placed over blood vessels), press and drag the gate or line on the image
- To change the Doppler steer for obtaining the best flow profile, press the icon, and drag. Note that steering of the ROI is only available on linear scanners (L7, L15, and L20).
- To change the gate size, slide up and down on the two arrows just below the gate area
- To change the correction angle (which should be adjusted to be parallel with the vessel in which the Doppler flow is being measured), slide up and down on the curved arrows to the side of the gate. Alternatively, single tap on the gate itself to cycle between -60, 0, and 60 degrees.
Needle Enhancement
Needle Enhancement uses state-of-the-art patented algorithms that help identify the needle and continually optimize to remove anatomical reflection artifacts, leading to superior needle identification. To see a video tutorial, please visit the Clarius Classroom using the Needle Enhance mode.
Strain Elastography
Elastography helps differentiate the elastic properties and relative stiffness of soft tissue. Turn on Elastography through the E option within the modes menu. There are multiple controls that can be used to adjust Elastography imaging.
The following region of interest (ROI) controls are available.
- To change the ROI position, press the center of the ROI and drag.
- To resize the ROI, press the icon, and drag.
The Elastography Map can also be used to adjust various parameters. The Elastography Map represents the relative stiffness of tissue. The color showing towards the top of the map correlates to softer tissue (S), and the color showing towards the bottom of the map correlates to harder tissue (H).
- To invert the Elastography Map, tap on the map once. This will alternate the red and blue colors that are used to visualize stiffness.
- To change the opacity (the level of transparency) of the elastography overlay, slide up and down on the Elastography Map. While changing the opacity, the value will be shown temporarily at the top of the image.
