2008-01-01 · This chapter gives a brief review and discusses the applications of the laser Doppler perfusion imaging (LDPI) technique and its role in clinical diagnosis of cancer. The considerations for the successful applications of this technique along with some of the potential advancement are presented in this chapter.

The aim of this study was to evaluate the benefit of high-resolution laser Doppler perfusion imaging (LDPI) in the differential diagnosis of pigmented skin tumours. One-hundred-and-eighty-nine patients were examined with the LDPI, 22 with malignant melanomas, 39 with clinically suspicious dysplastic melanocytic naevi and 27 with basal cell carcinomas.

Gourav Banerjee Leeds Beckett University 2009-10-01 2002-11-01 We present a full field laser Doppler imaging instrument that enables real-time in vivo assessment of blood flow in dermal tissue and skin. The instrument monitors the blood perfusion in an area The aim of this study was to evaluate the benefit of high-resolution laser Doppler perfusion imaging (LDPI) in the differential diagnosis of pigmented skin tumours. One-hundred-and-eighty-nine patients were examined with the LDPI, 22 with malignant melanomas, 39 with clinically suspicious dysplastic melanocytic naevi and 27 with basal cell carcinomas. Laser Doppler perfusion imaging (LDPI), is a further development in laser Doppler flowmetry (LDF). Its advantage is that it enables assessment of microvascular blood flow in a predefined skin area rather than, as for LDF, in one place. In many ways this method seems to be more promising than LDF in the assessment of burn wounds. Laser Doppler perfusion imaging in coronary by-pass surgery Abstract: Visualizing the spatial distribution of tissue blood flow by laser Doppler perfusion imaging (LDI) reveals a dependence of the system amplification factor on both the distance to the tissue from the detector and the incident angle of backscattered light on the detector surface.

Laser Doppler Flowmetry (LDF) is an established method for measuring the microcirculatory blood flow using either a fiber optic probe (laser Doppler perfusion monitoring, LDPM) or an imaging system (laser Doppler perfusion imaging, LDPI). The technique is based on the Doppler frequency shift that occurs when
