由于目前的标准筛查方法往往无法在转移发生前诊断乳腺癌，因此早期乳腺癌诊断仍然是一个重大挑战。为了改善这种情况，我们目前正在开发一种全三维超声计算机断层扫描（3D USCT）系统，有望获得高质量的乳腺体积图像。为了获得这些图像，必须执行耗时的重建。由于目前这是在PC上完成的，可重构硬件中的并行处理可以加速信号和图像处理。在这项工作中，我们调查了现有的数据采集（DAQ）系统的适用性，进一步的计算任务。嵌入式FPGA的可重构功能已被利用，以增强系统的功能。我们对DAQ系统进行了调整，以允许双向通信并提供整体过程控制。实验结果表明，该系统可用于数据处理。
As today′s standard screening methods often fail to diagnose breast cancer before metastases have developed, an earlier breast cancer diagnosis is still a major challenge. To improve this situation, we are currently developing a fully three‐dimensional ultrasound computer tomography (3D USCT) system, promising high‐quality volume images of the breast. For obtaining these images, a time‐consuming reconstruction has to be performed. As this is currently done on a PC, parallel processing in reconfigurable hardware could accelerate both signal and image processing. In this work, we investigated the suitability of an existing data acquisition (DAQ) system for further computation tasks. The reconfiguration features of the embedded FPGAs have been exploited to enhance the systems functionality. We have adapted the DAQ system to allow for bidirectional communication and to provide an overall process control. Our results show that the studied system can be applied for data processing.
