Imaging modes

Superb B-Mode (2D) imaging for anatomical visualization and quantification, with enhanced temporal resolution with frame rates up to 740 fps (in 2D for a 4x4 mm FOV), and enhanced image uniformity with multiple focal zones
M-Mode for visualization and quantification of wall motion in cardiovascular research, single line acquisition allows for the very high-temporal (1000 fps) resolution necessary for analysis of LV function
Anatomical M-Mode for adjustable anatomical orientation in reconstructed M-Mode imaging; software automatically optimizes field of view for maximum frame rate

M-mode imaging of mouse left ventricle

Pulsed-Wave Doppler Mode (PW) for quantification of blood flow
Color Doppler Mode for detection of blood vessels including flow directional information and mean velocities; as well as for identification of small vessels not visible in B-Mode

Color Doppler imaging in the mouse spleen

3D-Mode Imaging for anatomical and vascular visualization, when combined with either B-Mode, Power Doppler Mode or Nonlinear Contrast Imaging; allows for quantification of volume and vascularity within a defined anatomical structure
