The invention comprises a method and apparatus for sampling a common tissue volume and/or a common skin layer skin of a person as a part of noninvasive analyte property determination system, comprising the steps of: providing an analyzer, comprising at least three detectors at least partially embedded in a probe housing, the probe housing comprising a sample side surface, the detectors including a first and second range of detection zones of differing radial distances from a first illumination zone and second illumination zone, respectively coupled to separate sources; repetitively illuminating the illumination zones of the skin with photons in a range of 1200 to 2500 nm; and detecting portions of light from the sources with the at least three detectors, the detectors positioned on a common line with the sources.

Breast reconstruction and/or mastectomy may be performed to treat or prevent breast cancer or for a variety of other purposes. These procedures can result in disruption of the innervation of the breast, leading to loss of sensation. This loss of sensation can lead to diminishment of sexual function, sexual dysfunction, or other undesired effects. Devices and methods are provided for quantitatively assessing the tactile acuity of the breast at multiple locations. These embodiments can be applied to assess the natural acuity of the breast to design or calibrate an implanted system for restoring perception in the post-reconstruction breast. These embodiments can be also applied to assess the change in the perceptual acuity of the breast due to reconstruction or some other surgical intervention.

A control method of an apparatus according to an aspect of the present disclosure includes acquiring first vibration data that indicates a vibration of the apparatus produced by a speaker outputting a sound. Then the control method includes storing the acquired first vibration data in a memory. Further, the control method includes acquiring second vibration data that is generated by a vibration sensor detecting a vibration including a vibration based upon a body movement of a user on bedding on which the apparatus is placed. And the control method includes generating amended data by amending the acquired second vibration data using the first vibration data stored in the memory.

A system for pulmonary elastography includes an ultrasound probe (120) configured to evaluate tissue of a target area by transmitting a signal and receiving a response. A contact device (126) is coupled to the ultrasound probe to provide contact between the ultrasound probe and the tissue. An image processing module (110) is configured to output one or more elastograms according to the response.

The various embodiments herein disclose a method and a system with a portable handheld diagnostic device for detecting and/or monitoring the prognosis of nerve impairment or diabetic peripheral neuropathy. The system provides a multi-parameter diabetic neuropathy-screening device to perform a combination of tactile threshold test, vibration threshold test, thermal threshold test and contactless skin-temperature measurement. The present invention provides a smartphone application that helps a user to operate/control the device, store and share the results. The smartphone application interacts with the hardware modules in the device and guides the user to perform the various tests. Further, the neuropathy diagnostic system provides a wireless feedback button that enables the subject to respond to various sensations during the course of the test.

The invention comprises an applied force-optic analyzer used to determine a sample constituent concentration, a physical measure of the sample, and/or a state of the sample. The analyzer comprises: an electro-mechanical transducer affixed to skin of a subject; a controller, the controller providing a voltage waveform to the electro-mechanical transducer driving displacement of the skin and inducing a pressure wave into the skin; and a spectrometer interfaced to a sample site of the skin, the spectrometer comprising a set of sources and a set of detectors, where the controller is configured to collect signal from the set of detectors as a function of timing of the voltage waveform and apply a calibration model to the signal to determine the analyte concentration.

a) A Gabor domain optical coherence microscopy (GD-OCM) system providing high resolution of structural and motion imaging of objects such as tissues is combined with the use of reverberant shear wave fields (RevSW) or longitudinal shear waves (LSW) and two novel mechanical excitation sources: a coaxial coverslip excitation (CCE) and a multiple pronged excitation (MPE) sources providing structured and controlled mechanical excitation in tissues and leading to accurate derivation of elastographic properties. Alternatively, general optical computed tomography (OCT) is combined with RevSW or LWC in the object to derive elastographic properties. The embodiments include (a) GD-OCM with RevSW; (b) GD-OCM with LSW; (c) General OCT with RevSW; and General OCT with LSW.

An ultrasonic diagnostic imaging system performs elastography using mechanically generated vibrations from a vibration assembly attached to an ultrasound probe. An attachment member attaches the vibration assembly to the probe. A vibration motor is mounted in a motor mount and applies vibration energy to the body in which shear waves are to be measured, at a location adjacent to the probe. The vibration motor mount is coupled to the attachment member by a vibration isolation element such as a spring, rubber band, or elastic compound which isolates the probe from deleterious vibration energy from the vibration motor.

A system and method for automatic reading skin for an allergy to a substance, includes a consumer electronics device that acquires images of skin; a consumable member having a surface divided into elementary areas, each elementary area with a different possible allergenic substance; and a palette that, when applied against each elementary area brings the depositing part into contact with the skin thereby depositing the corresponding possible allergenic substance on or under the skin, where an image processing operation of the image of the skin taken by the consumer electronics device localizes the location that each depositing part has deposited the possible allergenic substance during the application and provides information in relation with a sensitivity of the skin, as indicated by a visible reaction, to the possible allergenic substance at each localized location.
