In this paper, the no-sampling linear sampling method is applied to microwave imaging of cancerous tissues in realistic models of female breast obtained from magnetic resonance imaging (MRI). The adopted formulation is based on a modified version of the far-field equation, sensitive to anomalies with respect to the healthy breast. The healthy configuration is taken into account through the related Green's function, which is numerically computed. The adopted imaging technique is assessed against the inspection of tumors of several positions and sizes in noisy environments. Moreover, a numerical analysis of the robustness of the method is performed when the model parameters used for evaluating the Green's function are not exactly known.
本文将无抽样线性抽样方法应用于从磁共振成像（MRI）获得的女性乳房现实模型中的癌变组织的微波成像。所采用的公式基于对健康乳房敏感的远场方程的修正版本。健康配置通过相关的格林函数来考虑，该函数通过数值计算得到。所采用的成像技术针对在噪声环境中检查多个位置和大小的肿瘤进行了评估。此外，当用于评估格林函数的模型参数不完全已知时，还对该方法的稳健性进行了数值分析。
