Phantom model of the breast which has actual shape and size has been developed for evaluation of microwave imaging by Chirp Pulse Microwave Computed Tomography (CP-MCT). This phantom model will also be successfully used for hyperthermia experiments using microwaves. This phantom model is consisted of four kinds of tissue mimicking materials, that is, the skin-, breast fat-, muscle-, and tumor-simulators. The principal ingredients of the phantom are water, liquid paraffin, super stuff (TX-150), sugar, and salt. It is easy to simulate permittivity of the real breasts in addition to the shape and size. This is the advantage of this non-homogeneous phantom. CP-MCT is a modality for microwave imaging of a human body using chirp pulse microwaves to extract the component which transmits the straight path between two antennas. Possibility of tumor detection by CP-MCT has been demonstrated by using the higher frequency model of CP-MCT and the non-homogeneous breast phantom.
已开发出具有实际形状和尺寸的乳房幻影模型，用于通过线性调频脉冲微波计算机断层扫描（CP-MCT）评估微波成像。该幻影模型也将成功用于微波热疗实验。该幻影模型由四种组织模拟材料组成，即皮肤模拟器、乳房脂肪模拟器、肌肉模拟器和肿瘤模拟器。该幻影模型的主要成分是水、液体石蜡、超级材料（TX-150）、糖和盐。除了形状和尺寸外，它还易于模拟真实乳房的介电常数。这是这种非均匀幻影模型的优势。CP-MCT是一种利用线性调频脉冲微波对人体进行微波成像的方式，以提取在两个天线之间沿直线传播的成分。通过使用CP-MCT的高频模型和非均匀乳房幻影模型，已证明了CP-MCT检测肿瘤的可能性。
