One aspect of the invention relates to a method for intraoperative detection of parathyroid gland viability in a surgery, comprising obtaining speckle contrast images of a parathyroid gland of a patent; and displaying the speckle contrast images of the parathyroid gland in real-time.

An imaging system for viewing a surgical site, the imaging system including a system controller configured to: receive and process video images of the surgical site captured by an endoscopic camera coupled to an endoscope to detect at least one video signature corresponding to at least one condition that interferes with a quality of the video images; and in response to detecting the at least one video signature corresponding to the at least one condition that interferes with the quality of the video images, control a fluid system to clean a tip of the endoscope based on at least one learned preference that was learned by the system controller from user action over time

A system facilitating differentiation between parathyroid tissue and thyroid tissue of a subject comprises a light source for illuminating tissue in a target region in the neck area of the subject; a light delivery device that is optically coupled with the light source for delivering a beam of light from the light source to the tissue; a collection device for collecting optical signals emitted from the tissue responsive to the beam of light; and a detector for detecting the intensities of the optical signals emitted from the tissue, wherein differences in the detected intensities enable a user to differentiate between parathyroid tissue and thyroid tissue.

Systems, devices and methods for providing active and/or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and/or compression stockings to provide feedback to modulate the compression treatment parameters.

An earpiece module includes a housing configured to be attached to an ear of a person, a first audio sensor within the housing configured to detect auscultatory sounds from an ear canal of the ear and generate a physiological information signal from the auscultatory sounds, and a second audio sensor within the housing and oriented in a direction towards an outside environment of the person. The second audio sensor is configured to detect sounds external to the person including voice sounds and footstep sounds, and to generate an environmental information signal from the external sounds. A processor is configured to receive the physiological information signal and the environmental information signal, process the external sounds in the physiological information signal and the environmental information signal to reduce the voice sounds and the footstep sounds from the physiological information signal and generate a cleaner physiological information signal.

A method for enhancing the performance of an imaging system that includes providing a magnetic resonance imaging system; providing an object to be imaged, wherein the object has a shape, includes a region of interest therein, and has a first dielectric constant; providing a pad that conforms to the shape of the object and contains a material having a second dielectric constant that is higher than the first dielectric constant; surrounding the pad and the object being imaged with at least one radio frequency coil; using the at least one coil to generate a magnetic field having an intensity of 3 T that extends through the material of the pad and into the region of interest of the object being imaged, and wherein positioning the at least one coil to surround the pad and the object increases the intensity of the magnetic field produced by the at least one coil within the region of interest of the object; using the at least one coil to detect the magnetic field generated in the region of interest of the object being imaged and to convert the detected magnetic field into detectable electrical signals; and increasing signal to noise ratio of detected electrical signals and decreasing required power input to the at least one coil through the placement of the at least one coil around the pad.

Disclosed embodiments describe techniques for body part motion analysis using kinematics. Two or more sensors, which include stretch sensors or inertial sensors, are attached to a body part of an individual. The two or more sensors enable collection of motion data of the body part. Data is collected from the two or more sensors, where the two or more sensors provide electrical information based on a micro-expression of movement of the body part. One or more processors are used for analyzing the electrical information from the two or more sensors to generate a kinematic phase pattern. The kinematic phase pattern is rendered as part of a kinematic sequence, where the rendering is displayed visually. The rendering includes an animation and enables additional kinematic analysis. The two or more sensors capture two or more modalities of body part motion.
