摘要： Parametric ultrasonic measurements which characterize the structure of tissue, using information from an ultrasonic signal beyond amplitude information, are obtained by combining multiple ultrasonic signals acquired at different angles, thereby reducing the variance of the calculations. Such angular compounding may be applied to detecting scatterer size, spacing, density, and attenuation.
摘要翻译：通过使用来自超声信号超出振幅信息的信息来表征组织结构的参数超声测量是通过组合在不同角度获取的多个超声信号来获得的，由此减少了计算方差。这种角度复合可以应用于检测散射体尺寸，间隔，密度和衰减。

摘要： A highly constrained image processing method is used to improve the quality, including spatial resolution and signal-to-noise ratio (SNR), of ultrasound image frames. Ultrasound image frames are accumulated to form a composite image that contains a priori information about the subject being imaged. This composite image is used in a HYPR processing method to improve the quality of the ultrasound image frame. For example, the SNR of the composite image is increased as a function of the number of ultrasound image frames used to produce it, and this increased SNR is passed on to each highly constrained image frame. Additionally, high spatial resolution ultrasound images are produced using an undersampled sampling density, and the quality of these images is restored to substantially the same level as a fully sampled image.
摘要翻译：使用高度受限的图像处理方法来提高超声图像帧的质量，包括空间分辨率和信噪比（SNR）。累积超声图像帧以形成包含关于被成像对象的先验信息的合成图像。该复合图像用于HYPR处理方法以提高超声图像帧的质量。例如，合成图像的SNR作为用于产生合成图像的超声图像帧的数量的函数而增加，并且将增加的SNR传递到每个高度约束的图像帧。此外，使用欠采样密度产生高空间分辨率超声图像，并且将这些图像的质量恢复到与完全采样图像基本相同的水平。
