Burns measurement

moorLDI - Laser Doppler Imager

The laser Doppler (LD) technique assesses tissue blood flow, by analysing the Doppler shift of low power laser light from moving red blood cells. Clinical trials have shown that burn wounds heal within 21 days where there is high LD blood flow but require grafting where LD blood flow is low.

Burn depth assessment image Key to the image above

The moorLDI laser Doppler images the whole burn wound and maps burns depth. A full resolution scan includes 65,536 individual laser Doppler measurements and these are displayed alongside a corresponding 'photo' image, as a colour coded image.



  • Image size up to 256x256 pixels (not interpolated) with 1 mm resolution

  • Image area - 5x5cm (at 20cm distance) to 50x50cm (at 100cm distance)

  • Scan time - 4,10 or 50ms per pixel (under 5 minutes for full scan)

  • Windows-based software for control, processing & analysisis

  • Multipler patient & image file formats - moorLDI, ASCII, BMP,PCX, TIFF

  • Optional Dual Wavelength system allows simultaneous measurement from two vascular beds

  • Optional High Resolution system using 100-micron laser beam
