Ultrasonic imaging has become increasingly important as a diagnostic tool in medicine because it is noninvasive and it can provide valuable information otherwise unattainable. However, at present, clinical interpretation of an ultrasonic image still mostly relies on recognition of boundaries and positional relationship of anatomical structures and a subjective analysis of the distribution or texture of echo amplitudes. Other potentially useful information carried back by the echoes is completely discarded. The aim of ultrasonic tissue characterization research is to develop methods to extract additional information from the returned echoes so that tissue pathology or abnormality can be reliably identifed and severity of the pathology objectively assessed with quantitative criteria. A number of ultrasonic parameters including acoustic velocity, impedance, attentuation and scattering, have been utilized in attempting to achieve this goal. In this paper, recent progress in this research will be discussed and relevant results presented.
超声成像作为一种医学诊断工具已变得越来越重要，因为它是非侵入性的，并且能够提供通过其他方式无法获得的有价值信息。然而，目前超声图像的临床解读在很大程度上仍依赖于对解剖结构边界和位置关系的识别以及对回波幅度分布或纹理的主观分析。回波携带的其他潜在有用信息则被完全舍弃。超声组织表征研究的目的是开发从返回的回波中提取额外信息的方法，以便能够可靠地识别组织病理学或异常情况，并使用定量标准客观评估病理学的严重程度。为了实现这一目标，人们已经利用了包括声速、阻抗、衰减和散射在内的许多超声参数。本文将讨论该研究的最新进展并展示相关结果。
