The Visual Sonics Vevo 3100 system is an in vivo high resolution ultrasound imaging system, specially designed for in-vivo small animal (rodent) imaging.
The system allows anatomical, morphological and functional 2D/3D imaging, with resolutions as low as 30 µm. It is equipped with an isoflurane anesthesia and monitoring system enabling respiratory and cardiac gating, a variety of transducers designated for anatomical, vascular and cardiac rodent imaging, an adjustable rail system and a physiology plate for easy animal positioning and handling.
In our Institute, we have two available tranducers :
- • The MX550D (25-55 MHz), with axial resolution of 40 µm.
- • The MX250 (15-30 MHz), with axial resolution of 75 µm.
B-Mode is a two-dimensional ultrasound image display composed of bright dots representing the ultrasound echoes. The brightness of each dot is determined by the amplitude of the returned echo signal. This allows for visualization and quantification of anatomical structures, as well as for the visualization of diagnostic and therapeutic procedures for small animal studies.
Heart - B Mode
Heart - M Mode
M-mode examines a line of Motion over time. Using M-mode in echocardiography displays the movement of the myocardium allowing for accurate and real-time measurements of wall thickness, internal diameter, and heart rate. It is from these parameters that many systolic parameters are derived (i.e. fractional shortening, ejection fraction, chamber volumes, etc.).
