A medical device position guidance system includes a plurality of noninvasive external detector devices communicable with an invasive medical device. A magnetic field is used to gather information about the anatomical size and shape of a subject, such as a human. The medical device position guidance system further uses the magnetic field to obtain information about the positioning of the invasive medical device relative to the subject's anatomy. A method of using the medical device position guidance system is also provided.

Some aspects of the invention may be directed to a system and method of determining an occurrence of inter-vascular occlusion. The method may include: receiving, from a first sensor, a first indication, related to blood flow in a first artery supplying blood to a first hemisphere of a subject's brain; receiving from one of: the first sensor and a second sensor, a second indication related to the blood flow in a second artery supplying blood to a second hemisphere of the subject's brain; comparing the first and second indications; and determining an occurrence of an inter-vascular occlusion based on the comparison.

A body measurement device and a method for controlling the same are disclosed. The body measurement device comprises a TOF camera capturing a first image that includes an RGB image and a depth image; a display displaying a graphic image; and a controller estimating a user's pose based on the first image, controlling the TOF camera to automatically capture a second image, which includes the user's body image in front of the camera, if the user's pose is a first pose, generating the user's body line image based on the captured second image, measuring the user's body size based on the generated body line image; and controlling the display to display the user's body size.

The present invention discloses a wearable device and methods of monitoring changes in the volume and properties of human interstitial fluid associated with both normal and disease conditions using limb circumference and acceleration. The raw data are transmitted from the wearable device to external devices for storage and evaluation. The data is compared and contrasted with reference information derived for the individual as well as a larger population of individuals and evaluated for wellness and clinical implications. Messages regarding the state of the individual may then be transmitted to concerned parties such as patients, caregivers and medical professionals.

A blood volume monitor includes a carrier mountable on a subject's body part. A measuring arrangement is mounted on the carrier. The measuring arrangement provides data relating to a change in volume of the body part, and outputs signals representative of the change. A control unit is in communication with the measuring arrangement to process data output by the measuring arrangement to determine, using the volume data, the volume of the body part and determines blood volume in the body part. The control unit uses the response signals received from the measuring arrangement and the determined volume of the part of the body to determine the blood volume.

Devices and methods to measure gastric residual volume (GRV) are described where at least one additive component (a GRV indicator) may be dispersed in a body lumen such as a stomach. The GRV indicator may changes a physical (chemical, electrical, thermal, mechanical, optical, etc.) characteristic within the stomach by a measureable degree. This degree of change and/or the rate of return to the previous state, may be used to determine the GRV of a patient. The determined GRV can also be used to automatically or semi-automatically control the patient's feeding rate and/or volume and/or frequency to adequately nourish the patient but avoid complications. The physical characteristic(s) may also be used to detect that the feeding catheter or tube is in the correct location (ie stomach vs lung or esophagus.

Embodiments of the invention include a cloud-assisted rehabilitation system for assisting in the rehabilitation of musculoskeletal conditions, and a method for rehabilitating patients having musculoskeletal conditions. A rehabilitation portal can aggregate and de-identified musculoskeletal rehabilitation information that is gathered from various intelligent musculoskeletal rehabilitation apparatuses attached to a group of patients. The rehabilitation portal can facilitate crowd communication among the group of patients. A particular rehabilitation experience can be compared with other rehabilitation experiences and data from other patients. The rehabilitation portal can also facilitate crowd communication among a group of healthcare professionals so that the plurality of healthcare professionals can communicate with each other and compare information regarding different rehabilitation experiences based at least on the aggregated de-identified musculoskeletal rehabilitation information.

Disclosed are methods for quantification of a perivascular space in a subject's central nervous system. The methods include administering contrast agent into cerebrospinal fluid of the subject; performing quantitative ultra-short time-to-echo contrast-enhanced magnetic resonance imaging (QUTE-CE MRI) on a region of interest of the subject's brain; and determining presence of the contrast agent in the perivascular space within the region of interest.

The present disclosure provides methods, systems, and devices for coregistering imaging data to form three-dimensional superimposed images of a biological target such as a wound, a tumor, or a surgical bed. A three-dimensional map can be generated by projecting infrared radiation at a target area, receiving reflected infrared radiation, and measuring depth of the target area. A three-dimensional white light image can be created from a captured two-dimensional white light image and the three-dimensional map. A three-dimensional fluorescence image can be created from a captured two-dimensional fluorescence image and the three-dimensional map. The three-dimensional white light image and the three-dimensional fluorescence image can be aligned using one or more fiducial markers to form a three-dimensional superimposed image. The superimposed image can be used to track wound healing and to excise cancerous tissues, for example, breast tumors. Images can be in the form of videos.
