在这项工作中，我们提出了一个用于微波乳腺癌检测的可穿戴患者界面的临床原型。该原型机的长期目标是用于乳房健康监测应用。该系统使用多静态时域脉冲雷达，在胸罩中嵌入了16个柔性天线。与之前报道的基于桌子的原型机不同，这种可穿戴式原型机不需要浸泡介质，可以简单地定位乳房表面。与基于桌子的原型相比，可穿戴设备的成本效益也显著提高，占地面积也更小。为了证明可穿戴原型的改进功能，我们在这里报告了一名健康志愿者在28天内每天对新的可穿戴原型进行测试的结果。将结果数据（包括信号和重建图像）与基于表的原型获得的数据进行比较。我们表明，可穿戴原型的使用通过每一项调查措施提高了收集的志愿者数据的质量。这项工作证明了可穿戴式乳房健康监测阵列的概念验证，该阵列可以在未来进一步优化，用于不同乳房大小和组织密度的患者。
In this work, we present a clinical prototype with a wearable patient interface for microwave breast cancer detection. The long-term aim of the prototype is a breast health monitoring application. The system operates using multistatic time-domain pulsed radar, with 16 flexible antennas embedded into a bra. Unlike the previously reported, table-based prototype with a rigid cup-like holder, the wearable one requires no immersion medium and enables simple localization of breast surface. In comparison with the table-based prototype, the wearable one is also significantly more cost-effective and has a smaller footprint. To demonstrate the improved functionality of the wearable prototype, we here report the outcome of daily testing of the new, wearable prototype on a healthy volunteer over a 28-day period. The resulting data (both signals and reconstructed images) is compared to that obtained with our table-based prototype. We show that the use of the wearable prototype has improved the quality of collected volunteer data by every investigated measure. This work demonstrates the proof-of-concept for a wearable breast health monitoring array, which can be further optimized in the future for use with patients with various breast sizes and tissue densities.
