Abstract
In general, the invention provides methods for use in the acquisition and display of ultrasound images. In particular, the invention provides methods for displaying ultrasound images using gating of ultrasound acquisition based on subject respiration and/or triggering ultrasound acquisition based on subject ECG. The methods may be employed with any suitable ultrasound system.
Claims19
A method for ultrasound signal acquisition for ultrasound imaging, comprising:
- acquiring a respiration signal from a subject;
- determining a start of a respiration cycle in the respiration signal;
- setting a valid zone based on the start of the respiration cycle and user defined offset and/or duration;
- acquiring a plurality of frames of ultrasound;
- discarding one or more frames of the plurality of frames acquired outside the valid zone;
- and
- outputting one or more remaining frames of the plurality of frames acquired inside the valid zone.
A method for ultrasound signal acquisition for ultrasound imaging, comprising:
- acquiring, at a host computer, an ECG signal from a subject;
- acquiring, at the host computer, a respiration signal from the subject;
- identifying, at the host computer, an R-wave point in the ECG signal;
- determining, at the host computer, a trigger point threshold and a trigger slope based on the R-wave point;
- transferring the trigger point threshold and the trigger slope to a programmable logic device;
- and
- triggering, by the programmable logic device, the acquisition of ultrasound based on the trigger point threshold and the trigger slope.
