SYSTEMS AND METHODS FOR VIDEO-BASED MONITORING OF VITAL SIGNS
The present invention relates to the field of medical monitoring, and in particular non-contact, video-based monitoring of pulse rate, respiration rate, motion, and oxygen saturation. Systems and methods are described for capturing images of a patient, producing intensity signals from the images, filtering those signals to focus on a physiologic component, and measuring a vital sign from the filtered signals. Examples include flood fill methods and skin tone filtering methods.
METHOD AND APPARATUS FOR VIDEO INTERPRETATION OF CAROTID INTIMA-MEDIA THICKNESS
A system for automatically determining a thickness of a wall of an artery of a subject includes an ECG monitoring device that captures an electrocardiogram (ECG) signal from the subject, and an ultrasound video imaging device, coupled to the ECG monitoring device, that receives the ECG signal from the ECG monitoring device, and captures a corresponding ultrasound video of the wall of the artery of the subject. The system produces a plurality of frames of video comprising the ultrasound video of the wall of the artery of the subject and an image of the ECG signal. A processor is configured to select a subset of the plurality of frames of the ultrasound video based on the image of the (ECG) signal, locate automatically a region of interest (ROI) in each frame of the subset of the plurality of frames of the video using a machine-based artificial neural network and measure automatically a thickness of the wall of the artery in each ROI using the machine-based artificial neural network.
CUSTOM DATA FIELDS FOR AUTOMATED APHERESIS PROCEDURES
A method and automated system for processing blood in which the automated system includes a programmable controller, a database, and an interactive display screen for displaying information and receiving operator input. The programmable controller is configured to automatically control the system to perform the method. Upon activation of the system, the screen displays a listing of different blood processing procedures that may be performed using the system. The operator may then input into the controller an identification of a specified blood processing procedure that is to be performed, such that an initial list of parameters that are associated with the specified blood processing procedure are displayed on the screen. The operator may then input into the controller an identification of the parameters that are to populate the display screen during performance of the procedure and indicate a format in which the selected parameters are to be presented on the display screen. The controller then creates a display for the specified blood processing procedure. Current values of the selected parameters in the selected format are displayed on the screen during performance of the specified procedure. The controller automatically saves an image of the display screen periodically during performance of the specified blood processing procedure, and transfers information from the saved images of the display screens to a procedure record form.

Method and system for monitoring and evaluation of pressure ulcer severity
Evaluating a pressure ulcer includes: detecting in a color input image a boundary of the pressure ulcer to get a RGB region of interest (ROI) image; converting the RGB ROI image to a grayscale ROI image; processing the grayscale ROI image using a Linear Combination of Discrete Gaussians (LCDG) process to estimate three main class probabilities of the grayscale ROI image; processing the RGB ROI image using predetermined RGB values to estimate the three main class probabilities of the RGB ROI image; and combining the probabilities of the grayscale ROI image and the probabilities of the RGB ROI image to determine an estimated labeled image; and normalizing and refining the estimated labeled image using a Generalized Gauss-Markov Random Field (GGMRF) process to produce a final segmentation image.
Electroanatomical map re-annotation
A method, including receiving from mapping electrodes positioned at locations within a heart, signals indicating electrical activity in tissue contacting the electrodes, and processing the signals to identify, for each location, at least one corresponding LAT in a cycle of a heart. For each location, an earliest LAT in the cycle is identified, and an electroanatomical map including mapping points having respective locations and showing the earliest LAT at each location is generated and rendered. An input selecting a subset of the points is received, and a time range containing the earliest LAT of a majority of the points in the subset is identified. One or more outlying points in the subset are identified, and a second LAT, later than the earliest LAT in the cycle is found among the at least one identified LAT identified at the outlying points. The map is updated to display the found second LAT.
