Features and Benefits:
- Our moorLDI2-IR™ laser Doppler blood perfusion imager uses a near infra-red laser beam (785nm in the standard moorLDI2-IR™ imager).
- The Laser Doppler is currently positioned on a mobile table in room 1302 and can be moved if necessary
- The moorLDI2-IR Moor Instruments’ Standard blood flow imager. As a direct result of employing a 2mW near infra red laser scanning beam, it is highly sensitive, has a wide dynamic range , high resolution and can be operated in fast or slow scan modes (for even higher sensitivity and greater dynamic range). In fast scan mode the time for 256 x 256 scan measurements is about 5 minutes.
- The default upper bandwidth of the signal (Doppler frequency shift) processor is 15kHz, so that in fast scan mode the range of red blood cell speeds that contribute to the recorded image is about 0.075mm/s to 6mm/s. In its slow mode, appropriate for imaging very low flows the range is about 0.01mm/s to 6mm/s.
- The MoorLDI uses a 12bit A/D in the signal processor plus amplifier gain settings of x4 and x16 which enables the accurate imaging of these very low flow areas in slow scan mode. (The processor effectively works as a low noise 16 bit system.)
When imaging with the Doppler, animals need to be anesthetized. To reserve a portable anesthesia machine, contact Karen Brocklehurst, COM Facility Manager, at 974-9806 or firstname.lastname@example.org. Researchers must provide their own isoflurane.
