Photoacoustic imaging of small animals

Learn about Vevo® Technology ( Vevo 3100)
The Vevo® platform was the world’s first commercially available high-frequency array based ultrasound imaging system and has since emerged as the gold standard in small animal anatomical and functional in vivo imaging. The Vevo Family of high-frequency Ultrasound products enables the researcher to obtain in vivo anatomical, functional, physiological and molecular data simultaneously, in real-time and with a resolution down to 30 µm. The system is easy to use, non-invasive and fast, providing extremely high throughput when needed.  It is designed with the researcher in mind, with system presets and animal handling tools for fast image acquisition and numerous protocols, software and data management tools optimized for today’s scientists.

The Vevo LAZR Imaging System
Photoacoustic imaging is a new in vivo hybrid imaging modality that combines the sensitivity and contrast of optical imaging with the depth and resolution of ultrasound. When pulsed laser light illuminates tissue, the optical absorbers there (such as hemoglobin) undergo thermoelastic expansion, generating an acoustic pressure wave which is detected with an ultrasound transducer.

The Vevo LAZR system incorporates photoacoustic imaging into high-resolution ultrasound. The ultrasound imaging provides a high-resolution frame-of-reference for identifying anatomy, while the photoacoustic imaging enables functional measurements such as oxygen saturation, total hemoglobin and the microdistribution of biomarkers.

Advantages of Photoacoustic Imaging

•   Optical contrast for blood and molecular imaging

•   High-resolution at depth

•   Real-time Non-invasive

•   Anatomical, functional and molecular data
