Problems solved by technology

However, the combination of information from different frames may result in blurred images or inaccurate information due to operator motion or internal motion
Motion correction between frames in a sequence may not fully correct blur since the imaged tissue may move relative to other tissue

Embodiment Construction

[0014] The processor extracts frames of contrast agent data on the same cardiac phase across different cardiac cycles. The frames of contrast agent data on a given cardiac phase are aligned. The contrast agent data may be aligned with B-mode data. The contrast agent frames aligned on the same cardiac phase across different cardiac cycles are combined. A calculation of a moving average, MIP, or parameter (such as time to peak) is performed on the motion-corrected contrast agent frames.

[0015] Left ventricle imaging (LVO) and myocardial contrast echocardiography (MCE) are the two main applications of contrast acoustics. Both applications can be improved by performing motion corrected imaging from frames with a common phase of the cardiac cycle. Speckle noise can be reduced, and the signal-to-noise ratio can be improved. Contrast resolution and microcatheter visibility can also be improved.

Abstract

The present invention relates to synchronized combining for contrast agent enhanced medical diagnostic ultrasound imaging. The invention provides a contrast agent enhanced medical diagnostic imaging, a system for the contrast agent enhanced medical diagnostic imaging and a corresponding computer readable storage medium. Frames of data from common phase periods are grouped. Motion correction is performed within each common phase group. An image representing contrast agents is formed from a combination of the frames within each common phase, motion corrected group.

Description

technical field [0001] The present invention relates to contrast agent enhanced medical diagnostic ultrasound imaging. More specifically, contrast agent image information is combined over time. Background technique [0002] Contrast echocardiography is a widely used technique for imaging the heart. One of the main applications is left ventricle visualization (LVO), in which contrast agent microbubbles opacify the left ventricle and thereby provide better visualization of the intracardiac border. An evolving application of acoustic contrast is myocardial contrast echocardiography (MCE), where the contrast agent microbubbles provide traces corresponding to the microcirculation as well as to myocardial perfusion. Imaging blood perfusion within organs or tissues may be useful. In some applications, frames of data collected over time are integrated. The resulting images can provide useful information for diagnosis, such as revealing smaller ducts or perfusion channels. [00...
