Abstract

We are developing instrumentation for adaptive multimodality imaging, a form of non-linear optimization where imaging parameters are automatically adjusted in response to the object. We have designed and built an adaptive, helical-scan cone-beam x-ray CT system suitable for small-animal studies and are retrofitting one of our existing FastSPECT systems to add adaptive capabilities. We discuss the system designs and how adaptive strategies can provide an increase in performance on various medical imaging tasks relative to current imaging procedures.

摘要

我们正在开发用于自适应多模态成像的仪器，这是一种非线性优化形式，其中成像参数会根据对象自动调整。我们已经设计并构建了一种适用于小动物研究的自适应螺旋扫描锥束X射线CT系统，并正在对我们现有的一台FastSPECT系统进行改造，以增加自适应功能。我们讨论了系统设计，以及相对于当前成像程序，自适应策略如何能在各种医学成像任务中提高性能。
