A novel approach to tomographic data processing has been developed and evaluated using the Jagiellonian positron emission tomography scanner as an example. We propose a system in which there is no need for powerful, local to the scanner processing facility, capable to reconstruct images on the fly. Instead, we introduce a field programmable gate array system-on-chip platform connected directly to data streams coming from the scanner, which can perform event building, filtering, coincidence search, and region-of-response reconstruction by the programmable logic and visualization by the integrated processors. The platform significantly reduces data volume converting raw data to a list-mode representation, while generating visualization on the fly.
已经开发并评估了一种新的层析数据处理方法，该方法使用雅盖隆大学正电子发射断层扫描系统作为示例。我们提出了一种系统，该系统不需要强大的、与扫描仪本地的处理设备，而是能够实时重建图像。相反，我们引入了一个现场可编程门阵列系统级芯片平台，该平台直接连接到来自扫描仪的数据流，可以通过可编程逻辑执行事件构建、滤波、符合搜索和响应区域重建，并通过集成处理器进行可视化。该平台通过将原始数据转换为列表模式表示，同时实时生成可视化，显著减少了数据量。
