Effective burn scar treatment requires objective measurement of burn severity and progression, and 3D scanning technologies could offer a valuable alternative to the current clinical assessments. This article discusses the use of 3D scanning to determine the area and extent of burns. The study involves a comparison of twelve burns in six patients using two CAD software. The article deals with the methodology of scanning burns, and subsequently describes in detail the methodology of determining the area of burns from a 3D scan. Methodologies for burn scanning and determining burn area from 3D scans were detailed, emphasizing the innovation's potential in surpassing traditional assessment methods like the Rule of nine and Palm method estimation. Twelve burns were scanned at least twice, allowing comparison of the burn area before and after a certain period of healing. The study revealed that 3D scanning provides an accurate approach to measuring burn areas, with minimal differences observed between software. Meshmixer software emerged as the preferred tool due to its intuitive features, underscoring the potential of 3D scanning to improve burn assessment and treatment planning. This approach enables the use of 3D scans to determine individual treatment according to the progression of healing, and at the same time opens up the possibilities of using 3D scans to design burn orthoses.
BACKGROUND: In clinical practice, ultrasound assessment of the skin and superficial tissues is progressively becoming a valuable diagnostic tool to support physical examination in the outpatient setting. OBJECTIVES: The aim of this study was to define a standardized sonographic approach to (layer-by-layer) accurately evaluate multiple histological layers of the skin and superficial tissues. METHODS: Using high-frequency ultrasound probes and high-level ultrasound machines, we matched the histological microarchitecture of superficial tissues with multiple sonographic patterns in physiological and pathological conditions. Moreover, high-sensitive color/power Doppler assessments have also been performed to evaluate the microcirculation. RESULTS: Modern equipment allow for a detailed "sonographic dissection" of the skin and superficial tissues by evaluating different histological layers in various clinical scenarios. High-sensitive Doppler imaging clearly depicts the microvasculature, especially of pathologies. CONCLUSIONS: In clinical practice, using adequate technological equipment, a detailed sonographic assessment of the superficial (soft) tissues can be performed with the use of high-frequency B-mode and high-sensitive Doppler imaging.

Main symptoms found in patients with same diseases as for example COVID-19 is febrile. The infrared thermography (IRT) represents a fast measurement in case of screening in public places. One of the limitations of IRT is the resolution of sensor, which has close connection with the distance between camera and ROI. To maximize the effectivity of resolution of the camera is to reduce the distance from the object. The aim of presented study showed the possibility how to protect the camera or medical staff that operates the device against potential infection or contamination from the person with infection. Two protective foils of different thickness (40 μm; 9 μm) were tested as a barrier between the IRT and the ROI (black body model and human face). Even though the results have shown that the transparent foils decrease linearly the measured value of the temperature, it can be used as a protective barrier between IRT and the object if an appropriate recalculation is done during analysis of IRT images. Results are acceptable in the case of 9μm foil especially. The authors see this possibility as a minor concession from IRT standards but as a great help in health protection. The transparent foil can be used as protective barrier of the infrared camera.

BACKGROUND: The aim of this article is to present a new methodology for assessment of skin topology using a three-dimensional image (3D). METHODS: The measurement of the skin surface roughness is based on 3D scanning of silicone replicas by chromatic aberration length technique in a contactless manner, i.e. by a polychromatic light beam. Analysis of the skin surface reprints was performed using Talymap, Gold version. Results were analysed by fractal geometry, which allows to evaluate changes of the skin surface before and after application of cosmetics and instrumental cosmetological techniques. The methodology was applied for objective assessment of the effects of diamond microdermabrasion on the skin surface roughness. Measurements were performed on 23 volunteers in the age group of 31-67 years. RESULTS: Based on the results of skin surface scanning after the treatment with diamond microdermabrasion it may be concluded that inequalities of the skin surface are reduced immediately after exfoliation. However, this effect mostly diminishes within 14 days after treatment. The entire study ultimately suggests that the instrumental method used only leads to improvement of the skin surface immediately after its application. Thermo vision images of the skin surface temperature were obtained during the application of the abrasive method. The experimental results showed that the skin is rather cooled than heated by the treatment. CONCLUSION: This study is focused on the development of a methodology for objective measurement of changes in treated skin relief using 3D scanning. The results are evaluated using fractal dimension. The output may also include also an enlarged model of the skin surface made by 3D printer, which can serve for illustrative communication with the client.
