Take-Home Messages •Characterization of breast tissue phantom models in the higher millimeter frequency range, i.e., D band (110-170 GHz), provides possible biomedical applications of D band-based imaging setups for non-invasive breast tumor margin assessment during lumpectomy procedures. •The dielectric properties of breast tissue phantoms have been explored in the D band using the waveguide probe calibration-based method, followed by an analysis of the electromagnetic properties of fat, fibrous, and tumor mimicking models through the study of transmission and reflection properties. •We find applications in imaging of excised tumors during breast conserving surgery through study of transmission and/or reflection properties using a non-invasive compact setup and utility in breast tumor margin analysis utilizing the dielectric contrast between normal and malignant tissues.

要点 •在较高毫米频率范围（即 D 波段 (110-170 GHz)）中表征乳腺组织模型模型，为基于 D 波段的成像设置在肿瘤切除术期间进行非侵入性乳腺肿瘤边缘评估提供了可能的生物医学应用程序。 •使用基于波导探头校准的方法在D波段探索了乳腺组织模型的介电特性，然后通过传输和反射特性的研究分析了脂肪、纤维和肿瘤模拟模型的电磁特性。 •我们通过使用非侵入性紧凑装置研究透射和/或反射特性以及利用正常组织和恶性组织之间的介电对比进行乳腺肿瘤边缘分析的实用性，发现了在保乳手术期间切除肿瘤成像的应用。
