“…Because of the importance of accurate blood flow visualization, various techniques for flow imaging have been proposed in medical fields such as ophthalmology, dermatology, endoscopy, and internal medicine (Stern et al, 1979). Some of these techniques are non-invasive and include methods such as Orthogonal Polarization Spectral (OPS) imaging (Groner et al, 1999), side Stream Dark Field (SDF) imaging (Goedhart et al, 2007), Laser Doppler Perfusion Imaging (LDPI) (Wardell et al, 1993) and laser speckle methods (Basak et al, 2016), such as Laser Speckle Contrast Imaging (LSCI). Among all these methods, LSCI is gaining interest because of its simplicity and ease of use.…”

“…Novel medical findings revealed the use of hyperspectral imaging tool by Fontaine et al [25] to investigate HbO 2 level of infected foot among the patients with DFU following medical surgery for removal of soft tissue and bone debridement. This technique has also proven successful to study the severity of peripheral vascular disease (PVD) through the distinguished changes in the S t O 2 map [26]. The results reported correlative changes between oxygen saturation and the severity of the disease.…”

A comprehensive understanding of the histological changes involved during different stages of healing would provide a better insight on the studies of wound healing assessment. The conventional method of assessing wound healing progress via visual inspection, although convenient, has certain limitations in terms of reliability and accuracy in its diagnosis. A more accurate approach previously employed to document wound recovery progress is based on changes in skin microcirculatory activities namely tissue oxygenation and blood perfusion level at different stages of wound healing. In this paper, the use of spectroscopy and laser speckle techniques is summarized for an effective wound healing management and to discover potential fields for future laboratory and clinical research. It is expected that the development in this research could provide an efficacious solution for clinical practitioners to come up with proper diagnosis with respect to different prescribed treatment.

“…This is to identify the effectiveness of the standard medical treatment towards diabetic wound healing rate with minimal evaluation time, and hence reducing the feeling of anxiety amongst the affected patients. It was also suggested in previous works that one could possibly obtain the histology information and tissue blood flow information using a multispectral imaging system [15,16]. Meanwhile, a study by Huong, Philimon, and Ngu [17] revealed a high association between blood perfusion and tissue oxygenation during the different stages of wound repair and regeneration.…”

“…While there have been in-vivo wound healing studies on characterization of hemodynamic changes and microvascularremodeling using the corresponding technique, very few findings were reported on human subjects. Instead, most experimental investigations were performed on animals such as rat and porcine models [15,21,22]. Similarly, Wang, Cull, Piper, Burgoyne, and Fortune [23] attempted to investigate blood flow changes in the glaucomatous optic nerve head using nonhuman primate model that resembles the likes of human subjects.…”

This paper aims to demonstrate the feasibility of using a low cost laser speckle imaging built for the detection of changes of tissue blood flow with different experimental conditions. Images of anterior portion of the wrist of four healthy adult volunteers illuminated by a laser source of wavelength 650 nm were collected via a monochromatic charge-coupled device (CCD) imager. The mean and standard deviation (SD) of blood flow perfusion was predicted as 3.92 ± 1.47 and 2.90 ± 1.39, respectively, for measurements at rest condition and during blood flow occlusion. This work showed the ability of the developed system to detect changes in blood flow perfusion with differences in the experimental conditions. However, further works are required to further confirm the suitability of the system before it is used for different clinical applications such as monitoring of blood flow during diabetic foot ulcers healing following standard medical treatment.
