In medical imaging, a fiducial marker facilitates tissue image correlation that allows for image analysis, normalization and correction of the optical exposure and spectral and spatial distribution in order to compensate for the surface reflections, sub surface tissue interactions and spatial orientation of the excitation and imaging axes to the subject tissue. Using a cross comparison, clinicians can model tissue image data in different forms in order to reference and compare data from various spectral components and or from different images. This may enhance human interpretation between images including the variations between images even when the spectral, spatial and optical conditions or the image resolution or sensitivity are compromised. Such may be used to assess cosmetic, moisturizing, therapeutic materials and treatments.

A method of measuring edema (e.g., peripheral edema and/or lymphedema) is described. The method involves directing a pulse of compressed air or other gas at a skin surface and determining the level of edema using processed camera images of the skin surface after indentation with the compressed air or other gas. The method can be completed within minutes, is simple to perform, and is free of user bias. Devices and systems for measuring edema and/or one or more skin-related properties are also described. The devices can be portable and suitable for use in medical or veterinary settings as well as for in-home/personal use.

A system (2) for transferring radio frequency energy to a composite structure (22) is provided that includes a radio signal generator (14) that produces a pulse modulated waveform with variable carrier frequency and variable pulse repetition frequency. The pulse modulated waveform is applied to the composite structure (22) for heating. An infrared imaging element (4, 6) measures the rate of heating in the composite structure (22) for particular values of the variable carrier frequency and the variable pulse repetition frequency. The infrared imaging element (4, 6) produces a representation illustrating the effects of heating on the composite structure (22) as well as the composite's molecular, nanoscopic structural, or chemical characteristics. A controller (8) determines the optimum variable center frequency and the variable pulse repetition frequency for optimum heating of the composite structure (22) while minimizing damage.

The method includes: acquiring a first image; performing at least one skin condition detection on the first image to acquire at least one first characteristic value; acquiring at least one second characteristic value acquired through the skin condition detection in the second image; determining whether a skin condition in the first image has changed with respect to a skin condition in the second image according to the first characteristic value and the second characteristic value; and if the skin condition in the first image has changed with respect to the skin condition in the second image, outputting notification information to indicate that the skin condition in the first image has changed with respect to the skin condition in the second image. The invention makes it possible to effectively and clearly determine change of the skin condition.

Systems, methods, apparatuses, and medical devices for harmonizing data from a plurality of non-invasive sensors are described. A physiological parameter can be determined by harmonizing data between two or more different types of non-invasive physiological sensors interrogating the same or proximate measurement sites. Data from one or more first non-invasive sensors can be utilized to identify one or more variables that are useful in one or more calculations associated with data from one or more second non-invasive sensors. Data from one or more first non-invasive sensors can be utilized to calibrate one or more second non-invasive sensors. Non-invasive sensors can include, but are not limited to, an optical coherence tomography (OCT) sensor, a bio-impedance sensor, a tissue dielectric constant sensor, a plethysmograph sensor, or a Raman spectrometer.

The present invention relates to the reduction of tissue interface pressure. The present invention provides a method to immerse an individual to a desired depth into a support surface. The method of the present invention maintains a desired level of immersion over time independent of the motion of the individual or changes in the position of the support surface or externally applied loads to the support surface, alone or in combination. The method of the present invention is an improvement to using an individual's weight or height or other sensor to determine inputs to an algorithm for immersing the individual to a certain depth into the surface. No pressure measurements or displacement measurements are required in accordance with the present invention, and the height and weight of the individual is not required.
