作为心脏组织运动多普勒显示研究的一部分，对多普勒图像的速度分辨率、空间分辨率和准确性进行了研究。设计测试模型来执行这项工作，并在计算机上捕获图像。研究了体模图像和图像捕获过程的特性。在多普勒图像中观察到的最小细节为3 mm × 3 mm。多普勒接收增益和多普勒系综大小都影响速度分辨率。不同的靶材料给出了不同的速度分辨率的措施。这可能与材料的不同背散射强度有关。
An investigation has been carried out on the velocity resolution, spatial resolution and accuracy of Doppler images as part of a study into the Doppler display of cardiac tissue motion. Test-phantoms were designed to perform this work and images were captured on a computer. The characteristics of the phantom images and of the image capture process were studied. The smallest detail that was observed in the Doppler image was 3 mm by 3 mm. Doppler receive gain and Doppler ensemble size both affected velocity resolution. Different target materials gave different measures for velocity resolution. This could be related to the different back-scatter intensities of the materials.
