“…n Modern in vivo imaging techniques for dermatology In recent decades, a number of different optical and nonoptical imaging devices have been developed [3][4][5][6][7][8] that are capable of either screening large areas, or enlarging and contrasting minute details at cellular or subcellular resolution. Among the nonoptical techniques, high frequency ultrasound with acoustic spectral bandwidths above the commonly implemented frequencies around 20 MHz was evaluated for cancer diagnostic purposes [9].…”

High-resolution frequency domain optical coherence tomography (OCT) stands out amongst a range of novel dermatologic imaging technologies, with its good detection sensitivity around -100 dB, high measurement speeds allowing real-time image acquisition and its ability to acquire high definition crosssectional and 3D tomograms of regions greater than 1 cm 2 , providing tissue information comparable to conventional histopathology without the need for any contrast agents. Typical axial and transverse resolutions of state-of-the-art OCT systems range between 1-10 µm and approximately 20 µm, respectively, depending on the employed wavelength region. This review investigates the significant progress accomplished in the field of dermatologic OCT with respect to other in vivo diagnostic methods for preexcisional imaging of nonmelanoma skin cancers and specifically emphasizes state-of-the-art results achieved in different clinical pilot studies. Further technological extensions of OCT, various multimodal imaging approaches as well as potential clinical dermatologic applications are discussed.KEYWORDS: cancer diagnosis n contrast-enhanced imaging n dermatology n functional imaging n microscopy n multimodal imaging n optical coherence tomography n optical imaging n tomography

“…Professionals dealing with wound patients make clinical decisions principally but not solely based on their visual perception (1–4). The descriptive analysis of wounds, however, is still poorly standardised and rarely reproducible (5–12). Measurement of time‐related changes based on digital images of wounds is optimised by new developments in calibration techniques (13–15).…”

Wound bed area measurements are considered to be an essential part of the wound assessment process. Wound care professionals should be aware of the reliability and validity of the techniques they use. The purpose of this study was to assess whether wound care professionals are able to make as accurate and reproducible a measurement of the wound bed area using two methods for area measurement. Five wound care professionals independently assessed 2285 digital wound images for the wound bed area. Each image was measured in random order, three times, and in four angles by providing the rotated versions of each image (0°, 90°, 180° and 270°). Two techniques were compared: free hand drawing and closed polygon (CP) graph algorithm. Comparison of the two techniques showed differences that are, in our opinion, not acceptable in clinical practice when these techniques are used interchangeably and/or the measurements are carried out by different observers. Variations observed between wounds and observers seem related to the difference in perception of the wound bed margin. Our results indicate that repetition of CP graph area measurement results in the lowest difference in repetitive measurements. Study limitations are related to an incomplete consensus on definitions of wound, wound bed, wound edge and wound border. The development of an ontology related to wound images could aid to reduce these ambiguities.

“…4 In addition, advances in digital dermoscopy and microscopy 5 are also improving academic and research capabilities. 6 Digital imaging systems for acquiring and archiving wholebody skin images have been used successfully in early melanoma detection in high-risk persons, 7 and digital image review may be used in ''store-and-forward'' teledermatology for ''virtual'' diagnosis in emergency care 8 and clinic and teaching settings. [9][10][11][12][13] Digital photos have been used successfully to improve the diagnostic accuracy of dermatopathology evaluations 14 and may also be taken at the bedside and viewed as a full-screen picture on a computer to allow surgical planning and teaching in another venue.…”
