Method and system for determining a period of interest using multiple inputs
First Claim
1. A method for identifying one or more periods of minimal motion, comprising the steps of:
- acquiring at least one set of non-electrical data representative of cardiac motion and one or more sets of data representative of respiratory motion;
generating a set of multi-input motion data comprising the set non-electrical data representative of cardiac motion and the one or more sets of motion data representative of respiratory motion; and
extracting one or more periods of minimal motion for one of a heart and a respiratory organ from the set of multi-input motion data.

Abstract
One or more techniques are provided for identifying a period of minimal motion for an organ of interest, such as the heart or lungs. Motion data is acquired for the organ of interest and for one or more proximate organs using sensor-based and/or image-based techniques. The sensor-based techniques may include electrical and non-electrical techniques. The image-based techniques may include both pre-acquisition and acquisition image data. The motion data for the organ of interest and proximate organs may be used to generate a set of multi-input motion data that may be processed to identify desired periods, such as periods of minimal motion, within the overall motion of the organ of interest.
