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.

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 mobile-platform imaging device uses compression of the target region to generate an image of an object. A tactile sensor has an optical waveguide with a flexible, transparent first layer. Light is directed into the waveguide. Light is scattered out of the first layer when the first layer is deformed. The first layer is deformed by the tactile sensor being pressed against the object, A force sensor detects a force pressing the tactile sensor against the object and outputs corresponding force information. A first communication unit receives the force information from the force sensor. A receptacle holds a mobile device with a second communication unit and an imager that can generate image information using light scattered out of the first layer. The first communication unit communicates with the second communication unit and the mobile device communicates with an external network.

Devices and methods are provide for facilitating registration and calibration of surface imaging systems. Tracking marker support structures are described that include one or more fiducial reference markers, where the tracking marker support structures are configured to be removably and securely attached to a skeletal region of a patient. Methods are provided in which a tracking marker support structure is attached to a skeletal region in a pre-selected orientation, thereby establishing an intraoperative reference direction associated with the intraoperative position of the patient, which is employed for guiding the initial registration between intraoperatively acquired surface data and volumetric image data. In other example embodiments, the tracking marker support structure may be employed for assessing the validity of a calibration transformation between a tracking system and a surface imaging system. Example methods are also provided to detect whether or not a tracking marker support structure has moved from its initial position during a procedure.

Disclosed are methods for determining biometric indicators such as plasma volume, hematocrit and glomerular filtration rate, in mammalian subjects such as humans. The methods utilize a plurality of fluorescent tags having distinct fluorescent characteristics, which may be associated with a single static molecule, or wherein the static molecule is labeled with a fluorescent tag and a dynamic molecule is labeled with another fluorescent tag. One or more measurements of the intensities of the fluorescent emissions are taken subsequent to introduction of an injectate which contains the fluorescent tags, which can be taken using a probe or via a blood or plasma sample. Compositions and apparatuses for practicing the methods are also disclosed.

In some embodiments, an example method or system consistent with the present disclosure may: obtain a desired property of a simulated trajectory of a virtual camera; receive a first video of a wound captured by a moving camera, the first video including a plurality of frames; use the desired property of the simulated trajectory of the virtual camera to analyze the first video to select at least two frames of the plurality of frames corresponding to the simulated trajectory of the virtual camera; use the desired property of the simulated trajectory of the virtual camera to select an order for the selected at least two frames; and rearrange the at least two frames based on the selected order to create a new video of the wound that represents the simulated trajectory of the virtual camera.

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.

Disclosed are processes including receiving at least a first and a second image data record corresponding to a first and a second point in time and including a first and a second one or more images of a wound; obtaining an image of the wound from a particular point of view corresponding to the first point in time by analyzing the first image data record; generating a simulated image of the wound from the particular point of view corresponding to the second point in time by analyzing the second image data record; and generating a visual time series view of the wound including at least the image of the wound from the particular point of view corresponding to the first point in time and the simulated image of the wound from the particular point of view corresponding to the second point in time.

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 analyzing wounds using standard user equipment, the operations including receiving one or more images of a wound of a patient; analyzing the one or more images to determine, based on at least a difference between values of two pixels of the one or more images, a condition of the wound; selecting an action based on the determined condition of the wound; and initiating the selected action.

Embodiments consistent with the present disclosure provide systems, methods, and devices for providing wound capturing guidance. In one example, consistent with the disclosed embodiments, an example system may: display, on a mobile device, a user interface configured to guide a patient through one or more steps for performing a medical action, the plurality of steps including at least: using at least one item of a medical kit; and capturing at least one image of at least part of the at least one item of the medical kit using at least one image sensor associated with the mobile device. The example system may also: detect a failure to successfully complete the medical action; select from one or more alternative reactions, a reaction to the detected failure likely to bring a successful completion of the medical action; and provide instructions associated with the selected reaction.
