20110064284 | METHODS, APPARATUS AND ARTICLES OF MANUFACTURE TO PROCESS CARDIAC IMAGES TO DETECT HEART MOTION ABNORMALITIES - Example methods, apparatus and articles of manufacture to process cardiac images to detect heart motion abnormalities are disclosed. A disclosed example method includes adapting a state of a state-space model based on a plurality of cardiac images to characterize motion of a heart, computing an information-theoretic metric from the state of the state-space model, and comparing the information-theoretic metric to a threshold to determine whether the motion of the heart is abnormal. | 03-17-2011 |
20110064290 | METHODS, APPARATUS AND ARTICLES OF MANUFACTURE TO TRACK ENDOCARDIAL MOTION - Example methods, apparatus and articles of manufacture to track endocardial motion are disclosed. A disclosed example method includes segmenting a plurality of cardiac images of a left ventricle to form respective ones of a plurality of segmented images, updating a plurality of models based on the plurality of segmented images to form respective ones of a plurality of motion estimates for the left ventricle, computing a plurality of probabilities for respective ones of the plurality of models, and computing a weighted sum of the plurality of motion estimates based on the plurality of probabilities, the weighted sum representing a predicted motion of the left ventricle. | 03-17-2011 |
20130251210 | METHODS, APPARATUS AND ARTICLES OF MANUFACTURE TO PROCESS CARDIAC IMAGES TO DETECT HEART MOTION ABNORMALITIES - Example methods, apparatus and articles of manufacture to process cardiac images to detect heart motion abnormalities are disclosed. A disclosed example method includes using a filter coefficient based on a plurality of cardiac images to characterize motion of a heart; computing an information-theoretic metric from the filter coefficient; and comparing the information-theoretic metric to a threshold to determine whether the motion of the heart is abnormal. | 09-26-2013 |
20140143643 | METHODS AND APPARATUS TO LABEL RADIOLOGY IMAGES - Methods and apparatus are disclosed to label radiology images. An example system includes a processor and a database. In response to receiving a first user input via a data input, the processor is to generate first annotations on a spinal image. The processor is to cause the spinal image having the first annotations to be displayed at a user interface. The processor is to prompt a user to provide second user input identifying an error in the first annotations. In response to receiving the second user input, the processor is to generate second annotations on the spinal image. The second annotations is to correct the error in the first annotations. | 05-22-2014 |
