在本文中，我们通过测量由压在乳房组织上的力传感器阵列产生的乳房皮肤应力模式来分析乳房弹性成像的物理基础。应力模式的时空变化允许检测具有不同弹性特性的内部结构，并评估这些结构的几何和力学参数。该方法在乳房机械成像仪（BMI）中实现，BMI是一种紧凑型设备，由配备压力传感器阵列的手持探头、紧凑型电子单元和触摸屏笔记本电脑组成。通过BMI获得的数据可以计算检测到病变的大小、形状、一致性/硬度和活动性。BMI原型已经在组织模型的实验室实验和正在进行的临床研究中得到验证。研究结果表明，BMI具有较高的灵敏度、定量记录存储、易用性和固有的低成本等优点，有可能成为一种筛查和诊断工具，在很大程度上取代临床乳腺检查。
In this paper, we analyze the physical basis for elasticity imaging of the breast by measuring breast skin stress patterns that result from a force sensor array pressed against the breast tissue. Temporal and spatial changes in the stress pattern allow detection of internal structures with different elastic properties and assessment of geometrical and mechanical parameters of these structures. The method entitled mechanical imaging is implemented in the breast mechanical imager (BMI), a compact device consisting of a hand held probe equipped with a pressure sensor array, a compact electronic unit, and a touchscreen laptop computer. Data acquired by the BMI allows calculation of size, shape, consistency/hardness, and mobility of detected lesions. The BMI prototype has been validated in laboratory experiments on tissue models and in an ongoing clinical study. The obtained results prove that the BMI has potential to become a screening and diagnostic tool that could largely supplant clinical breast examination through its higher sensitivity, quantitative record storage, ease-of-use, and inherent low cost.
