Echocardiography is a predominant modality for diagnosis of the heart by non-invasive and real-time observation of cross-sectional images of the heart. In addition, it has been recently shown that measurement of rapid transition of myocardial contraction/relaxation and propagation of heart-wall vibration would be useful for assessment of myocardial function and viscoelasticity. However, such measurements require a higher frame rate of
several hundred Hz. Therefore, we realized high frame rate echocardiography using parallel beamforming with unfocused transmit beams. On the other hand, there is another method for imaging, namely, diffraction tomography. It was reported that diffraction tomography realized high temporal and spatial resolutions simultaneously. One
of the problem of parallel beamforming with unfocused transmit beams is degradation of spatial resolution, and diffraction tomography may improve this problem. In this report, diffraction tomography is applied to high frame rate echocardiography with unfocused transmit beams, and spatial resolutions realized by diffraction tomography and parallel beamforming were compared. |
