A method of distinguishing benign and malignant skin conditions includes extracting a numerical value corresponding to an order parameter from an image of skin having a pigmented region. The numerical value of the order parameter may be utilized to assess the likelihood that a skin lesion is benign or malignant. The precise value may also be utilized to assess severity, which may include detecting changes in a skin lesion over time.

Methods and systems for digitally reconstructing a patient tissue sample are described herein. In one embodiment, the method may include projecting a first structured light pattern onto the patient tissue sample, receiving a first reflection of the first structured light pattern from the patient tissue sample, and reconstructing the patient tissue sample based on the first reflection and the projected first structured light pattern. In another embodiment, the system may include a projector adapted or configured to project the first structured light onto the patient tissue sample, a charge-coupled device (CCD) adapted or configured to receive the first reflection from the patient tissue sample, and a reconstruction device adapted or configured to reconstruct the patient tissue sample based on the first reflection and the projected first structured light pattern.

The device for detecting and/or determining the concentration of an analyte present in a tissue includes a sensor which is an optical fibre interferometer, and one interferometer arm being coated with an immobilised binding agent enabling selective binding of the analyte. The interferometer arm is mounted inside a guide enabling puncturing the tissue and performing an in situ measurement without the necessity to collect or prepare a sample. The guide is provided with a closed guide face, longitudinal perforations on sidewalls enabling the analyte to reach the binding agent, and an opening in the input end of the guide for introducing the interferometer with the arm into the guide. At the input end, the opening is sealed, enabling the isolation of the interior of the guide from the surroundings. The interferometer is mounted in a position in which the interferometer does not touch the inside walls of the guide.

A skin state determination method includes: acquiring a first measurement result including data obtained by a spectral camera measuring the skin of a user at a first time point, second time points before the first time point being different from each other; estimating, on the basis of the first measurement result, a first estimation result including at least one of a skin moisture content or hidden blemish conditions of the user at the first time point; and determining a skin state of the user on the basis of the first estimation result and second estimation results based on second measurement results, each of the second measurement results including data obtained by the spectral camera measuring the skin of the user at each of the second time points.

The present disclosure relates to an apparatus and method for synthetically making an ultra-wide imaging bandwidth in millimeter-wave frequencies, resulting in improved image resolutions to values previously unattained. The synthetic approach sums up a number of available sub-bands to build an unavailable ultra-wideband system. Each sub-band contains a transceiver unit which is optimized for operation within that specific sub-band. The number and position of the sub-bands can be adjusted to cover any frequency range as required for the specific application.

Methods and devices are disclosed for calibrating intensity of a light source in a system of evaluating a skin lesion using Elastic-Scattering Spectroscopy (ESS). The ESS system may illuminate a sample of the skin lesion with a pulse from the light source adjusted to a high output setting, receive a signal comprising an elastic scattering spectrum from illuminating the skin lesion sample at the high output setting, determine whether the received signal has an intensity that is greater than a saturation threshold associated with at least one optical detection sensor, and if so, store the elastic scattering spectrum from illuminating the skin lesion sample at the high output setting. If not greater than the saturation threshold, the ESS system may illuminate the skin lesion sample with a pulse from the light source adjusted to a low output setting, receive a signal comprising an elastic scattering spectrum from illuminating the skin lesion sample at the low output setting, and store the elastic scattering spectrum from illuminating the skin lesion sample at the low output setting.

An electromagnetic (EM)-based diagnostics and monitoring system and method for the non-Invasive diagnosis and monitoring of in-vivo and ex-vivo Skin Anomalies Using Lesion-Optimized Sensor System Design and Topology is disclosed herein.

The following disclosure discusses systems and methods of detecting and analyzing cutaneous conditions. According to one embodiment, a 2D image of the cutaneous condition and a set of 3D point clouds associated with the 2D image are captured using an image capturing device. The 2D image and the set of 3D point clouds are sent to a computing device. The computing device generates a 3D surface according to the set of 3D point clouds. Subsequently, the computing device receives a depth map for the 2D image based upon the 3D surface from another computing device such that the depth map comprises depth data for each pixel of the 2D image. The cutaneous condition may then be measured and analyzed based upon the depth map using the computing device.

The invention relates to a sensor for a terahertz imaging system, comprising an array of terahertz radiation receivers; and an array of terahertz radiation transmitters having the same pitch as the array of receivers, located between the array of receivers and an analysis zone located in the near field of the transmitters, and configured such that each transmitter emits a wave towards both the analysis zone and a respective receiver of the array of receivers.

A mobile-platform imaging device uses compression of the target region to generate an image of an object. A tactile sensor has an optical waveguide with a flexible, transparent first layer. Light is directed into the waveguide. Light is scattered out of the first layer when the first layer is deformed. The first layer is deformed by the tactile sensor being pressed against the object. A force sensor detects a force pressing the tactile sensor against the object and outputs corresponding force information. A first communication unit receives the force information from the force sensor. A receptacle holds a mobile device with a second communication unit and an imager that can generate image information using light scattered out of the first layer. The first communication unit communicates with the second communication unit and the mobile device communicates with an external network.
