PeriCam PSI System is a blood perfusion imager based on the laser speckle contrast analysis (LASCA) technology, also known as laser speckle contrast imaging (LSCI). It is a method that visualizes tissue blood perfusion in real time. LASCA provides new means to study the microcirculation in ways that were not possible in the past. PeriCam PSI System combines dynamic response and high spatial resolution in one instrument, providing both real-time graphs and video recordings of the tissue being studied. To further enhance its usability, dedicated application software, PIMSoft, has been developed.
PeriCam PSI System is available in two versions:
PeriCam PSI HR (High Resolution)
PeriCam PSI NR (Normal Resolution)
Both versions can be upgraded with zoom functionality.
Easy to get started, flexible to use
PeriCam PSI is easy to set up, get started and operate. It is flexible to adjust and position at any measurement angle. A color camera for documentation, an indicator laser and automated working distance calculation enhances simplicity. Regions of interest (ROIs) can be defined and updated before, during and after the recording, which enables real-time data analysis while recording and instant updates of data, graphs and images. Automated background compensation, even while recording, allows for stable and accurate measurements under varying lighting conditions.
System design
PeriCam PSI System uses an invisible near infra-red (NIR) laser (785 nm) for blood perfusion measurements. The beam is spread over the measurement area by a diffuser, creating a speckle pattern.
