近年来，超宽带（UWB）技术已经成为一种有前途的替代方案，可以在广泛的应用中使用。超宽带的潜在应用之一是医疗保健和成像，其动机是非电离信号，低成本，低复杂性，以及穿透介质的能力。此外，超宽带信号所覆盖的大带宽允许成像实验所需的非常高的分辨率。本文介绍了一种基于惠更斯原理（HP）的超宽带微波成像技术，将其应用于含有肿瘤的多层皮肤模型。HP的方法允许捕获对比度，从而可以在最终图像中区分感兴趣区域内的不同材料属性，并且它的简单性消除了在向前传播波时解决反问题的需要。因此，该方法可以识别和定位多层体内的重要散射体。通过对包含代表肿瘤的多层圆柱形皮肤模型的仿真验证了该技术。
In recent years, Ultra Wideband (UWB) technology has emerged as a promising alternative for use in a wide range of applications. One of the potential applications of UWB is in healthcare and imaging, motivated by its non-ionizing signals, low cost, low complexity, and its ability to penetrate through mediums. Moreover, the large bandwidth covered by UWB signals permits the very high resolution required in imaging experiments. In this paper, a recently introduced UWB microwave imaging technique based on the Huygens principle (HP), has been applied to multilayered skin model with an inclusion representing a tumor. The methodology of HP permits the capture of contrast such that different material properties within the region of interest can be discriminated in the final image, and its simplicity removes the need to solve inverse problems when forward propagating the waves. Therefore the procedure can identify and localize significant scatterers inside a multilayered volume. Validation of the technique through simulations on multilayered cylindrical model of the skin with inclusion representing the tumor has been performed.
