The wound care management of bedsore is important to long-term bedridden patients. The wound size is usually monitored by a consumer-graded camera and then calculated by computer-aided analysis. In this paper, we simulated a subcutaneous and dermal injury using vacuum cupping experiment and performed multispectral imaging with three wavelengths, including active 650 nanometers red light and 940 nanometers...
The scattering effect of laser light irradiation on a matter surface creates motion-sensitive “speckle patterns”. The resulted Laser Speckle Imaging (LSI) has attracted a lot of attention in medical applications such as wound healing, rodent cerebral blood flow, and peripheral circulation examination due to its capability in revealing regional microcirculation conditions of tissue capillaries. However,...
