Abstract
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.
Claims19
A method comprising:
- adapting a state of a state-space model based on a plurality of cardiac images to characterize motion of a heart;
- computing, via a processor, 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.
An article of manufacture storing machine-readable instructions that, when executed, cause a machine to:
- adapt a state of a state-space model based on a plurality of cardiac images to characterize motion of a heart;
- compute an information-theoretic metric from the state of the state-space model;
- and
- compare the information-theoretic metric to a threshold to determine whether the motion of the heart is abnormal.
An apparatus comprising:
- a motion estimator to adapt a state of a state-space model based on a plurality of cardiac images to characterize motion of a heart;
- an information metric processor to compute an information-theoretic metric from the state of the state-space model;
- and
- a classifier to compare the information-theoretic metric to a threshold to determine whether the motion of the heart is abnormal.
