Displays high-resolution, real-time ultrasound images and is equipped with a Class 4 laser for diagnostic imaging and fluid flow analysis in 3D.
Available Scanning Features for Vevo 3100 System:
| B-mode | System’s default imaging mode. Displays echoes in a two-dimensional view. Useful for locating anatomical structures within a conventional ultrasound image. |
| Pulsed Wave Doppler mode | Sends short, quick pulses of sound to measure the velocity and direction of in vivo blood flow. |
| Power Doppler mode | Measures flow dynamics based on doppler signal and visualized with a color map on an energy scale. Useful for detecting vascularization of subcutaneous and orthotopic tumors. |
| Nonlinear Contrast mode | Suppresses tissue signal to improve sensitivity in microbubble detection and quantification via a nonlinear response. |
| 3D mode | Collect and combine multiple B-mode slices to produce a whole image. Can be combined with other US and PA modes. |
| RF mode | Collect RF, Raw, and IQ format for offline analysis in correspondence with ultrasound image. *Not available in 4D-mode |
What is Photoacoustic Imaging?
PA-mode is a general term for collecting optical contrast from biological tissues via a pulsed laser light paired with an ultrasound transducer from signal (680-97023) and idler (1200-2000nm).
