The moorLDI2-HIR is suitable for a wide range of pre-clinical research investigations, more typically where smaller areas are under investigation. The system features unique focused optics to provide 50 micron pixel size and 512 x 512 pixel resolution for high resolution blood flow images. The scan areas range from just 2.5cm x 2.5cm up to 25cm x 25cm with scan times typically less than 5 minutes. Use of a focussed laser provides a deeper measurement depth, optimal for angiogenesis studies such as hind limb ischemia and tumour modelling and pre-clinical cerebral blood flow imaging. Highly refined image measurement and analysis software allows for flexibility in measurement set up and comprehensive analysis functions. The moorLDI2-HIR features a colour photo image of the scanned area and automatic distance measurement, making the positioning and comparison of images easier.
The system is in routine use in numerous laboratories and clinics globally and employs unique, optical design and signal processing in order to generate the highest resolution and clearest images of its class. Laser Doppler imaging (LDI) is often compared to laser speckle imaging and whilst there are some similarities, both techniques offer unique advantages. LDI (and moorLDI2-HIR in particular) generally offers deeper penetration enabling enhanced visualisation of small vessels below the tissue surface, perfect for pre-clinical studies. For certain applications these features are critical.
