在先进的成像研究中，如自适应波束形成、合成孔径成像和光声成像，预波束形成数据的采集是必不可少的。Ultrasonix公司已经开发了这样一种用于预波束形成数据的数据采集设备，称为SONIX-DAQ，但数据只能离线下载和处理，而不能实时流式传输。在这项工作中，我们开发了一个软件框架来扩展SONIX-DAQ的功能，以便近实时地流传输和处理数据。作为一个例子，我们将此功能应用于我们以前的工作，可视化前列腺近距离放射治疗种子的光声图像。在本文中，我们提出了我们的软件框架，将其应用于实时光声成像系统，包括实时数据采集和数据处理的近距离治疗的软件模块。
Acquisition of pre-beamformed data is essential in advanced imaging research studies such as adaptive beamforming, synthetic aperture imaging, and photoacoustic imaging. Ultrasonix Co. has developed such a data acquisition device for pre-beamformed data known as the SONIX-DAQ, but data can only be downloaded and processed offline rather than streamed in real-time. In this work, we developed a software framework to extend the functionality of the SONIX-DAQ for streaming and processing data in near real-time. As an example, we applied this functionality to our previous work of visualizing photoacoustic images of prostate brachytherapy seeds. In this paper, we present our software framework, applying it to a real-time photoacoustic imaging system, including real-time data collection and data-processing software modules for brachytherapy treatment.
