This disclosure provides a method for imaging lymph nodes and lymphatic vessels without a contrast agent. The method includes providing, using an optical source, an infrared illumination to a region of a subject having at least one lymphatic component, detecting a reflected portion of the infrared illumination directly reflected from the region using a sensor positioned thereabout, and generating at least one image indicative of the at least one lymphatic component in the subject using the reflected portion of the infrared illumination.

The invention provides a system and method for measuring vital signs (e.g. SYS, DIA, SpO2, heart rate, and respiratory rate) and motion (e.g. activity level, posture, degree of motion, and arm height) from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient's heart; and (ii) at least three motion-detecting sensors positioned on the forearm, upper arm, and a body location other than the forearm or upper arm of the patient. Each motion-detecting sensor generates at least one time-dependent motion waveform indicative of motion of the location on the patient's body to which it is affixed. A processing component, typically worn on the patient's body and featuring a microprocessor, receives the time-dependent waveforms generated by the different sensors and processes them to determine: (i) a pulse transit time calculated using a time difference between features in two separate time-dependent waveforms, (ii) a blood pressure value calculated from the time difference, and (iii) a motion parameter calculated from at least one motion waveform.

The disclosure demonstrates an attachment apparatus for optically coupling a mobile device camera to a lens of a medical examination device. The device incudes an attachment body wherein the proximal side of the attachment body is attached to a mobile device via a magnetic array that may be positioned in at least two different positions. The distal side of the attachment device includes an array of magnets to connect with the lens of a medical device. In one or more of the magnetic arrays at least one pair of axially magnetized magnets are positioned in antiparallel arrangement relative to each other to reduce the expanse of a magnetic field while at the same time increasing the magnetic field strength close to the magnetic poles.

This document describes assessing cardiovascular function using an optical sensor, such as through sensing relevant hemodynamics understood by pulse transit times, blood pressures, pulse-wave velocities, and, in more breadth, ballistocardiograms and pressure-volume loops. The techniques disclosed in this document use various optical sensors to sense hemodynamics, such as skin color and skin and other organ displacement. These optical sensors require little if any risk to the patient and are simple and easy for the patient to use.

An apparatus and method for insuring the proper alignment of a defected vein pattern and a projected vein pattern are disclosed. The apparatus enhances the visual appearance of veins so that an error that can lead to improper patient care or injury can be avoided.

Disclosed are systems and methods for rapid generation of simulations of a patient's spinal morphology that enable pre-operative viewing of a patient's condition and to assist surgeons in determining the best corrective procedure and with any of the selection, augmentation or manufacture of spinal devices based on the patient specific simulated condition. The simulation is generated by morphing a generic spine model with a three-dimensional curve representation of the patient's particular spinal morphology derived from existing images of the patient's condition.

An adjustable illuminator for photodynamically diagnosing or treating a surface includes a plurality of first panels and at least one second panel. The plurality of first panels have wider widths and the at least one second panel has a narrower width. The narrower width is less than the wider widths. The illuminator further includes a plurality of light sources, each mounted to one of the plurality of first panels or the at least one second panel and configured to irradiate the surface with substantially uniform intensity visible light. The plurality of first panels and the at least one second panel are rotatably connected. The at least one second panel is connected on each side to one of the plurality of first panels. The second panel acts as a “lighted hinge” to reduce or eliminate optical dead spaces between adjacent panels when the illuminator is bent into a certain configuration.

A computer-implemented method for diagnosing a medical condition of a patient is provided. The method can include causing, using one or more processors, an excitation source to emit an excitation light towards a region of interest of an artery, receiving, using the one or more processors and a detector, imaging data of the region of interest of the artery, generating, using the one or more processors and the imaging data, an image of the region of interest, determining, using the one or more processors, a risk region of an atheromatous plaque, based on the imaging data, and determining, using the one or more processors, that the patient has a severe case of an atheromatous plaque, based on the determined risk region of the atheromatous plaque.

In various embodiments, a method for determining a homogeneity of complexion is provided. The method may include provision of a digital image on which skin is portrayed and which is parameterized in a color space which is defined by a parameter set in which one of the parameters is a hue, identifying and/or defining at least one skin examination area in the transformed image, calculating a hue distribution in the at least one skin examination area, and determining at least one homogeneity value for the complexion based on the calculated hue distribution.

Disclosed is a body temperature measuring patch using an IR temperature sensor. The present embodiment provides a body temperature measuring patch using an infrared temperature sensor, which enables the body temperature to be measured more accurately and quickly when a body temperature is continuously monitored by applying a surface mounted device (SMD)-type infrared (IR) temperature sensor and thus implementing a patch-type thermometer.
