Disclosed herein is a system and method directed to detecting placement of a medical device within a patient body, where the system includes a medical device including an optical fiber having core fibers, each of the one or more core fibers including a plurality of sensors each configured to (i) reflect a light signal having an altered characteristic due to strain experienced by the optical fiber. The system further includes logic configured to cause operations of providing an incident light signal to the optical fiber, receiving reflected light signals of different spectral widths of the incident light from the sensors, processing the reflected light signals to detect fluctuations of a portion of the optical fiber, and determining a location of the portion of the optical fiber based on the detected fluctuations. In some instances, the detected fluctuations are caused by anatomical movement of the patient body.

Disclosed is apparatus and method for motion tracking of a subject in medical brain imaging. The method comprises providing a light projector and a first camera; projecting a first pattern sequence (S1) onto a surface region of the subject with the light projector, wherein the subject is positioned in a scanner borehole of a medical scanner, the first pattern sequence comprising a first primary pattern (P.sub.1,1) and/or a first secondary pattern (P.sub.1,2); detecting the projected first pattern sequence (S1′) with the first camera; determining a second pattern sequence (S2) comprising a second primary pattern (P.sub.2,1) based on the detected first pattern sequence (S1′); projecting the second pattern sequence (S2) onto a surface region of the subject with the light projector; detecting the projected second pattern sequence (S2′) with the first camera; and determining motion tracking parameters based on the detected second pattern sequence (S2′).

The disclosure provides a theseometer or proprioceptometer for objectively quantifying the proprioceptive performance of a subject such as a human. The disclosed theseometer is a device comprising a clear, rigid material or screen having or exhibiting a distinguishable target embraced by a series of concentric rings, a digital camera with a lens concentric to the target, a base unit comprising an electronic processor and memory for analyzing data and, optionally, a wheeled base to provide mobility and portability.

The present invention relates to sedation assessment. In order to facilitate sedation depth monitoring in an autonomous imaging setting, it is proposed to use the imaging modality itself to measure the response to suitable reflexes in order to determine the depth of sedation wherein suitable reflexes include, but are not limited to, the pupil reflex, so-called superficial reflexes and the withdrawal reflexes. In one embodiment, the pupil reflex may be measured in an MRI system by repeated interleaving of dedicated iris MR imaging with the conventional scan protocol. In another embodiment, superficial reflexes in response to stroking of the skin may be measured. This may involve a dedicated actuator that may be closely integrated with the imaging modality, e.g. an MR receive coil applied to the patient. Alternatively, remote haptic systems may be used. The reflex is then acquired with a suitable diagnostic imaging method. In another embodiment, the withdrawal reflex in response to pain may be measured. This may involve an actuator that induces sudden stitching pain or very local temperature-induced pain and that is closely integrated with the imaging modality, e.g. a pinching device integrated with a patient support or an MR receive coil applied to the patient. The reflex is then acquired with a suitable diagnostic imaging method.

Systems and methods for providing a customized exercise protocol to a computing device of a user. As the user performs the exercise protocol, one or more cameras of the computing device can track the user's movements. The user's movement are assessed to determine if proper form and technique is being used.

A pressing position and pressure measurement method based on PPG (photoplethysmographic) imaging, which only needs a camera to locate multiple pressing areas and measure corresponding pressure values without a pressure sensor. Before the measurement starts, only a simple calibration work is needed. With the gradual increase of the pressing pressure, the characteristics of PPG signals corresponding to diastolic pressure and systolic pressure will disappear one by one, and by recording two sets of pressure values and the corresponding PPG signal intensity values, the relation curve of the pressure versus blood perfusion changes can be fitted. Through this relation curve, the pressure values corresponding to different blood PPG signal intensities can be obtained. Different from the traditional technical route, the present disclosure provides a non-contact measurement method for determining the pressing location and measuring the pressure through a camera.

A method and system for remote diagnosis of a congestive heart failure in humans is presented. The method includes receiving a facial image of a patient, wherein the facial image is retrieved from a data store and captured from the patient; extracting, from the facial image, at least one facial feature indicative of a heart condition; classifying the extracted at least one facial feature using a classifier, wherein the classifier maps a plurality of candidate facial features to a plurality of scores indicating a stage of the heart condition; and determining a positive diagnosis and the stage of the heart condition of the patient based on the plurality of scores.

Provided is a measurement apparatus including a processor and a storage unit. The storage unit holds measurement data of each time point which is obtained by a photographing apparatus, and temporal-spatial constraints. The processor extracts a position of an object from the measurement data of each time point, determines whether the object satisfies the temporal-spatial constraints, and determines, based on a result of the determination on whether the object satisfies the temporal-spatial constraints, whether the object is an analysis target.

One of the objectives of this invention is to allow the conduction of audiometric evaluations in natural or artificial sound spaces, in a way that can be monitored and reproduced.

For that purpose, the inventors propose to create virtual environments which reproduce sound and visual characteristics of natural or artificial spaces.

In practice, a user experience is initiated between a subject and a virtual environment so as to simulate a specific audiometry test. Finally, a spatial auditory localization score is determined from measurements that will be carried out in the virtual environment.
