摘要:
Systems and methods are provided for training and monitoring administration of an inhaler medication. The system includes a mobile computing device that is configured to provide an augmented reality training and monitoring aid for asthma patients. The mobile device is programmed to capture video using a camera and sound recordings using a microphone in order to measure the patient's head position from the video and measure events relating to inhalation and exhalation from the microphone recordings. This real-time data is used to provide real-time testing and monitoring of the patient's technique for using an inhaler and an augmented reality training aid that informs the patients training. The mobile device is configured to collect background information from the patient relating to the patient's control over his or her asthma and can also interface with a back-end computing system for storing and maintaining related information.

Systems, methods and software products determine an overall motion and/or flexibility envelope for an individual. Movement and position data of the individual is captured and processed to generate an overall motion and/or flexibility envelope for the individual defining overall motion and/or flexibility of the individual. The systems include a flexibility server with memory and a processor adapted to receive movement and position data of the individual, a motion and/or flexibility analyzer, implemented as machine readable instructions stored in the memory and executed by the digital processor, capable of processing the movement and position data to generate an overall motion and/or flexibility envelope for the individual defining overall motion and/or flexibility of the individual.

Disclosed are systems and methods for generating wide-field optical coherence tomography angiography (OCTA) images. In embodiments, multiple OCTA scans of a sample are automatically acquired at overlapping locations. The systems and methods include functionality to adaptively control the scanning procedure such that eye blink and eye motion events are detected in real time and accounted for during 3D scan acquisition. Also disclosed are methods for detecting and correcting motion-related artifacts in OCTA datasets which allow for the longer scan times over larger fields of view required for wide-field imaging. These methods may include division of en face angiogram images into a set of motion-free parallel strips, and application of gross and fine registration methods to align overlapping strips into a motion-corrected composite image. A series of overlapping motion-corrected composite images may be combined into a larger montage to enable wide-field OCTA imaging using multiple OCTA scans.

The invention is directed to a method for analysing the position of a human body using a computing device, comprising the following steps: (a) capturing at least one frame; (b) detecting on the at least one captured image frame the position of joints of the at least one portion of the body; (c) registering the detected positions and predefined reference positions of the joints in a common reference system; (d) computing a displacement of at least one of the joints that minimizes the error between the detected position and the corresponding predefined reference position of said joints; (e) using output means of said computing device, providing an indication of said displacement as an output. In step (d), the computed displacement is at least one rotation of one of the at least one body part.

The present invention relates to a device, system and a method for generating a photoplethysmographic image carrying vital sign information of a subject. To provide an increased validity and robustness against motion, in particular against ballistocardiographic motion, the proposed device comprises an input interface (30) for obtaining image data of a skin region of a subject in at least two different wavelength channels, said image data comprising two or more image frames acquired by detecting light transmitted through or reflected from the skin region over time, wherein said image data comprise wavelength-dependent reflection or transmission information in said at least two different wavelength channels, a combination unit (31) for combining, per pixel or group of pixels and per time instant, image data values of said at least two different wavelength channels to obtain a time-variant pulse signal per pixel or group of pixels, and an image generation unit (32) for generating a photoplethysmographic image from a property of the respective pulse signals in a time window including at least two image frames.
摘要:
Disclosed is a scanning monitoring apparatus for medical imaging, the scanning monitoring apparatus comprising a controller unit and a display, wherein the controller unit during a scanning session is configured to obtain tracking data (102) of a subject in a medical scanner, obtain scanner data indicative of operating parameters of the medical scanner (104); determine an output of a verification function based on the tracking data and the scanner data (106); and control the scanning monitoring apparatus according to the output of the verification function (108). A notification signal may be provided if the output is indicative of an erroneous scanning.
