RFLSI III Laser Speckle Perfusion Imager
Robust Blood Perfusion Imaging System
System Overview
RFLSI III is a blood perfusion imaging system that helps researchers to monitor and record, the blood perfusion of any exposed tissues or organs for microcirculation studies, in real-time, and to visualize the quantified data.
The RFLSS III Laser Speckle Imaging System is based on LSCI (Laser Speckle Contrast Imaging) technology. With the advantages of its non-contact, high time resolution, high spatial resolution, and full-field rapid imaging, it provides a real-time dynamic blood flow monitoring and recording method for research in life sciences.
The RFLSS III’s high-definition and high-speed camera allow for recording minute details and changes in the microcirculation in microns and milliseconds. The all-in-one design improves the operability of the user.
Performance Advantages
- Analyze vascular perfusion volume, vessel diameter, vessel angle, and other data online and offline to meet hemodynamic research.
- Multiple data acquisition methods, including continuous acquisition, specified interval acquisition, specified frame number acquisition, etc.
- An indicating laser plus autofocus function makes it easy to use. High-definition camera (full-frame 2048 x 2048 resolution) helps you see the blood vessel endings and opens the world of blood vessel microcirculation images.
- A high-definition camera (full-frame 2048 x 2048 resolution) helps you see the blood vessel endings and opens the world of blood vessel microcirculation images.
- The high-speed camera (up to a maximum frame rate of 120 frames per second) allows the recording of changes every second and recording of more details of blood vessel changes post-intervention.
- Package-type support solutions.
