乳腺癌是妇女癌症死亡的主要原因之一。它的早期发现和更好的治疗已被证明可以显著挽救生命并降低高昂的费用。因此，乳腺成像系统必须识别和定位非常小的病变。本文研究了一种用于乳腺肿瘤检测的超声临床振幅重建成像（CARI）技术的超声传播有限元时域（FETD）模拟。CARI方法对于检测被脂肪组织包围的癌症特别有吸引力，因为它们在传统的超声图像中都是黑色的，很难识别肿瘤的大小。给出了数学建模框架。对二维和三维乳房模型进行了数值模拟，以评估CARI方法的灵敏度。三维模拟证实了二维乳房模型的定量结果。此外，研究还表明了fed模拟CARI模态的有效性。
Breast cancer is one of the leading causes of death from cancer among women. Both its earlier detection and better treatment have been shown to significantly save lives and reduce high costs. Thus, breast imaging systems must recognize and locate very small lesions. This work is concerned with the finite element time domain (FETD) simulation of ultrasound wave propagation for a recent ultrasound clinical amplitude reconstruction imaging (CARI) technique for the breast tumor detection. The CARI method is especially attractive for detecting cancer surrounded by fatty tissues because they both appear dark in a conventional ultrasound image and makes it hard to recognize the size of the tumor. The mathematical modeling framework is presented. Numerical simulations are performed for a 2D and 3D breast model to assess the sensitivity of the CARI method. 3D simulations confirm the quantitative results obtained for the 2D breast model. Moreover, the study shows the effectiveness of the FETD to simulate the CARI modality.
