Systems and methods are configured to detect and/or ablate cancerous tissue, such as during surgery. The system uses Laser Ramen Spectroscopy (LRS) or Surface Enhanced Raman Spectroscopy (SERS) to enhance a detection signal pursuant to a spectroscopy analysis of tissue. Rapid in situ detection of cancer can be combined with immediate laser thermal ablation of the cancerous tissue. The detection and ablation can occur before, during, or after surgical resection.

A method for monitoring an intrabody region of a patient. The method comprises intercepting electromagnetic (EM) radiation from the intrabody region in a plurality of EM radiation sessions during a period of at least 6 hours, calculating a dielectric related change of the intrabody region by analyzing respective the intercepted EM radiation, detecting a physiological pattern according to said dielectric related change and outputting a notification indicating the physiological pattern.

An electronic device and method for measuring user body information are provided. The method for measuring user body information includes detecting a contact of a user's body portion on at least two spots of a touch screen of the electronic device, upon detecting the contact of the user's body portion on the at least two spots of the touch screen, applying power to a first coil in the electronic device, and measuring the user body information using at least one of a voltage and a second current measured after a first current is induced across the user's body by a first magnetic field generated from the first coil as the power is applied.

The present invention provides a removable optical imaging device cap for use with a near infrared (NIR) light optical imaging device for detecting intracranial hematoma.

A catheter-based imaging apparatus comprises a catheter having a proximal end and a distal end. An optical emitter is configured to emit optical excitation signals from a distal portion of the catheter. One or more ultrasound transducers are configured for: (a) transmission of acoustic excitation signals from the distal portion of the catheter; and (b) detection of ultrasound response signals from an object of interest at or near to the distal portion of the catheter at frequencies which include a lower receive frequency at least as low as 10 MHz and a higher receive frequency at least as high as 35 MHz. The one or more ultrasound transducers are thereby configured to detect response signals comprising photoacoustic response signals from the object of interest at the lower receive frequency and high resolution imaging signals from the object of interest at the higher receive frequency.

An oximeter probe that takes into account tissue color (e.g., skin color or melanin content) to improve accuracy when determining oxygen saturation of tissue. Light is transmitted from a light source into tissue having melanin (e.g., eumelanin or pheomelanin). Light reflected from the tissue is received by a detector. A compensation factor is determined to account for absorption due to the melanin. The oximeter uses this compensation factor and determines a melanin-corrected oxygen saturation value.

Optical and/or thermal energy is directed onto target tissue, generating smoke. The smoke generated is collected and a spectrum of smoke generated from the tissue is measured. Based on the spectrum, the target tissue is characterized to be normal or non-normal such as cancerous.

An exemplary tissue detection and location identification apparatus can include, for example, a first electrically conductive layer at least partially (e.g., circumferentially) surrounding a lumen, an insulating layer at least partially (e.g., circumferentially) surrounding the first electrically conductive layer, and a second electrically conductive layer circumferentially surrounding the insulating layer, where the insulating layer can electrically isolate the first electrically conductive layer from the second electrically conductive layer. A further insulating layer can be included which can at least partially surrounding the second electrically conductive layer. The first electrically conductive layer, the insulating layer, and the second electrically conductive layer can form a structure which has a first side and a second side disposed opposite to the first side with respect to the lumen, where the first side can be longer than the second side thereby forming a sharp pointed end via the first side at a distal-most portion. The exemplary configuration can be used for (a) determination/detection of a tissue type using impendence of the electrically conductive layers, and/or (ii) determination of a location of at least one portion of the insertion device/apparatus. Another exemplary apparatus can include, for example, a base structure comprising a lumen extending along a length thereof, and at least one optically-transmissive layer circumferentially surrounding the base structure and provided at least at a distal end of the base structure. For example, in operation, the optically-transmissive layer can be configured to transmit a particular optical radiation at the distal end thereof toward a target tissue.

The terminal includes a touch panel including first electrodes arranged in a first direction and second electrodes arranged in the second direction intersecting the first direction, a display panel attached to the touch panel and to display an image, and a processor to control the touch panel and the display panel. In a measuring mode, the processor is configured to: apply a driving signal to the touch panel, the touch panel being configured to form an electric field and/or magnetic field when the driving signal is applied, and determine body composition of a user based on a sensing signal output from the touch panel in accordance with eddy current, the eddy current being induced to a body of the user by the electric field and/or magnetic field formed around the touch panel.

In general, devices, systems, and methods for fiducial identification and tracking are provided.
