DESCRIPTION (provided by applicant): The long-term goal of the proposed partnership is to develop, unify, refine and implement a new approach to quantitative ultrasound (QUS) imaging of biological tissues and mammary tumors by the quantification of tissue microstructure. In lay terms, if the research is successful, many breast abnormalities and lesions can be diagnosed without the need for a biopsy. The overall hypothesis of our partnership is that a set of QUS parameters can significantly improve breast lesion differentiation/classification. The primary QUS parameters to be exploited include attenuation, scatterer size, scatterer number density, and acoustic concentration (scatterer number density times their impedance change). Our goal in the first 5 years of this project is to lay the foundation for a new (possibly revolutionary but definitely evolutionary) diagnostic imaging capability through development, testing, and verification with simulations, phantoms, and in vitro and in vivo animal model experiments, as well as preliminary human subjecting testing. In the second 5 years we will extend the analysis beyond common breast lesions, begin Phase II clinical trials and work towards the creation of automated tools to assist in the diagnosis of breast abnormalities. The partnership is between engineers, acoustic physicists, statisticians and veterinary pathologists at UIUC and physicists, engineers, pathologists and radiologists at UW. The PI is William D. O'Brien, Jr. (UIUC), and functioning as the co-Pi is Timothy J. Hall (UW). Use of QUS imaging is medically significant because it offers a potentially real-time and noninvasive means of differentiation/classification tumor types and tracking their response to therapy. To this end, 5 specific aims are proposed, viz., 1) unify QUS algorithms with simulations, phantoms and animal tumor models in vivo, 2) associate acoustic microstructural measurements with anatomical scattering sources, 3) monitor the changes in QUS parameters with tumor growth in in vivo animal models, 4) compare tumors in human subjects with those in animal models, and 5) develop a major outreach activity.

描述（由申请人提供）：拟议合作伙伴关系的长期目标是通过量化组织微观结构来开发，统一，完善和实施生物组织和乳腺肿瘤的定量超声（QUS）成像的新方法。借此来看，如果研究成功，可以诊断出许多乳腺异常和病变而无需活检。我们合作伙伴关系的总体假设是，一组QU参数可以显着改善乳房病变分化/分类。要利用的主要QU参数包括衰减，散射器大小，散射数密度和声学浓度（散射数密度乘以其阻抗变化）。我们在该项目的前5年的目标是通过开发，测试和验证新的（可能是革命性但绝对进化的）诊断成像能力为基础，并通过模拟，体外和体内和体内动物模型实验以及初步的人类受试者测试。在第二个5年中，我们将扩展分析以外的乳房病变，开始II期临床试验，并致力于创建自动化工具，以帮助诊断乳房异常。 UIUC的工程师，声学物理学家，统计学家和兽医病理学家以及UW的物理学家，工程师，病理学家和放射科医生之间的伙伴关系。 PI是小威廉·奥布莱恩（William D.使用QUS成像具有医学意义，因为它提供了潜在的实时和非侵入性分化/分类肿瘤类型的方法，并跟踪其对治疗的反应。 To this end, 5 specific aims are proposed, viz., 1) unify QUS algorithms with simulations, phantoms and animal tumor models in vivo, 2) associate acoustic microstructural measurements with anatomical scattering sources, 3) monitor the changes in QUS parameters with tumor growth in in vivo animal models, 4) compare tumors in human subjects with those in animal models, and 5) develop a major outreach activity.
