“…This follows a long and consistent body of works demonstrating the efficiency of LDI in clinical studies. The technique was first used by Niazi et al [11] who demonstrated that the accuracy of LDI assessment was 100% compared with biopsy-histology and only 65% for clinical assessment. More recently Pape et al [9] performed an audit of their use of LDI in the assessment of burn depth and reported 97% accuracy with LDI.…”

“…Additionally, disturbances of the fluid refractive index resulting from large temperature fluctuations have caused the incident laser beam to wander and defocus [100]. In spite of this, LDPI technology has been demonstrated and used in the assessment of a plethora of clinical situations; for instance, assessment of burn extent [14,15] and relative perfusion [41,101,102], post-operative malignant skin tumour assessment [103], and in the study of arthritis and joint inflammation [104].…”

Physics has delivered extraordinary developments in almost every facet of modern life. From the humble thermometer and stethoscope to X‐Ray, CT, MRI, ultrasound, PET and radiotherapy, our health has been transformed by these advances yielding both morphological and functional metrics. Recently high resolution label‐free imaging of the microcirculation at clinically relevant depths has become available in the research domain. In this paper, we present a comprehensive review on current imaging techniques, state‐of‐the‐art advancements and applications, and general perspectives on the prospects for these modalities in the clinical realm.

Burn diagnosis using laser speckle light typically employs widefield illumination of the burn region to produce two-dimensional speckle patterns from light backscattered from the entire irradiated tissue volume. Analysis of speckle contrast in these time-integrated patterns can then provide information on burn severity. Here, by contrast, we use point illumination to generate diffuse reflectance laser speckle patterns of the burn. By examining spatiotemporal fluctuations in these time-integrated patterns along the radial direction from the incident point beam, we show the ability to distinguish partial-thickness burns in a porcine model in vivo within the first 24 hours post-burn. Furthermore, our findings suggest that time-integrated diffuse reflectance laser speckle can be useful for monitoring burn healing over time post-burn. Unlike conventional diffuse reflectance laser speckle detection systems that utilize scientific or industrial-grade cameras, our system is designed with a camera-phone, demonstrating the potential for burn diagnosis with a simple imager.
