VisualSonics Vevo 770 Ultrasound

VisSon4The VisualSonics Vevo 770 is a high frequency ultrasound scanner designed for small animals. The system generates high-resolution images at frequencies of 30-50 MHz, enabling in vivo assessment of anatomical structures and hemodynamic functions in longitudinal studies.

Modalities include B-Mode, M-Mode, Pulse-wave Doppler, Power Doppler, and Tissue Doppler.

The scanner has pulsed-wave Doppler for quantitative blood flow velocity and waveform measurements. The M-mode of the scanner monitors tissue motion, which is useful for characterizing blood vessels, heart dynamics and wall thickening. The scanner is equipped with 3D and power Doppler imaging for visualizing blood vessel branching and blood flow patterns spatially and temporally. The scanner’s Handling Platform maintains core temperature, and monitors the ECG and other physiological measurements.

Key features of the Vevo 770 include:

  • Non-invasive, in vivo visualization of embryonic (E5.5) through to adult mice in real time
  • Image resolution of anatomical and physiological structures of down to 30 microns
  • Rail system with physiological monitoring capabilities
  • Integrated Micro-Manipulation system
  • 3-D acquisition and visualization
  • 4 Scanheads available
    – 30 MHz: adolescent rat imaging
    – 35 MHz: mouse cardiology
    – 40 MHz: abdominal, embryonic and vascular imaging
    – 55 MHz: epidermal and bowel imaging
  • Imaging Modes:
    – B-Mode: real-time imaging
    – M-Mode: measure heart dynamics and wall thickening
    – Pulsed Wave Doppler: measure blood flow velocities
    – Power Doppler: measure vasculature around tumors
    – Tissue Doppler: measure myocardial strain
