An ingestible device is disclosed which can produce spectral data of one or more analytes, as well as associated methods for characterizing the gastrointestinal tract of a subject which contains such analytes. Related kits and systems are also disclosed.

A sensor system includes a probe, and a photon source configured to direct photons at the probe. The probe can emit light in response to receiving photons. The sensor system can include a photodetector configured to detect the light emitted from the probe, and a configured to cause the photon source to emit photons according to a first time-varying intensity profile having a first frequency. The controller can be configured to receive optical data from the photodetector based on the interaction between the light emitted from the probe and the photodetector. The optical data can include a second time-varying intensity profile having a second frequency. The second frequency can be substantially the same as the first frequency. The controller can be configured to determine a difference in phase between the first time-varying intensity profile and the second time-varying intensity profile, and generate a report based on the difference in phase.

A non-transitory computer readable medium storing data and computer implementable instructions that, when executed by at least one processor, cause the at least one processor to perform operations for generating cross section views of a wound, the operations including receiving 3D information of a wound based on information captured using an image sensor associated with an image plane substantially parallel to the wound; generating a cross section view of the wound by analyzing the 3D information; and providing data configured to cause a presentation of the generated cross section view of the wound.

Calibration imaging tips and related methods of use are described. In some embodiments, a calibration imaging tip may be positioned on a distal end portion of an imaging device to place a calibration surface within a predetermined distance of a focal plane of the imaging device. The imaging device may then be calibrated using one or more images of the calibration surface.

The present invention relates to a method and a device for enabling to analyze a property of a vital sign detector (20). The proposed method comprises the steps of providing a virtual phantom (14) of a living being, rendering an artificial vital sign on the displayed virtual phantom (14), and outputting the virtual phantom (14) with the rendered artificial vital sign to the vital sign detector (20).

Methods and systems for calibrating an instrument, such as a surgical instrument, within an imaging system are disclosed herein. In some embodiments, a method includes capturing images of the instrument with a plurality of cameras of the imaging system and identifying common features of the instrument in the captured images. The method further includes generating a three-dimensional (3D) representation of the instrument based on the common features and determining a reference frame of the instrument based on the generated 3D representation of the instrument. A first transform is determined between the reference frame of the instrument and a reference frame of the cameras. Then, a second transform between the reference frame of the instrument and a reference frame of the tracking structure can be determined based on the first transform.

An apparatus for estimating a biological substance in a user using a unit spectrum for the biological substance acquired using a biological tissue simulation solution is provided. The apparatus may include a spectrometer configured to emit a light to a skin of a user, detect the light returned from the skin, and measure a skin spectrum of the user from the detected light and a processor configured to estimate a biological substance in the user based on the measured skin spectrum and a unit spectrum acquired using a biological tissue simulation solution.
