We experimentally prepared a laser speckle flowgraphy (LSFG) device, and investigated whether it can accurately measure cutaneous blood flow. Cutaneous blood flow was measured in healthy adults using the thermal diffusion method (TDM) and strain-gauge plethysmography (SPG) established as blood flow measurement methods, along with LSFG. The correlation properties between the values measured by LSFG and TDM, and LSFG and SPG, were investigated. Results found that a significant positive correlation is noted between the two conventional methods and LSFG. It is suggested that LSFG is a useful device for cutaneous blood flow evaluation, and that its applications in medical care and esthetic fields are expected.
