具有结构促进调节剂的多模态成像
Multi-modality imaging with structure-promoting regularisers
摘要：
多模态或多通道成像对于我们的现代社会变得越来越重要。了解和早期诊断癌症和痴呆症的关键工具是PET-MR，这是一种结合正电子发射断层扫描和磁共振成像的扫描仪，可以同时获取功能和解剖数据。类似地，在遥感中，虽然高光谱传感器可以允许识别和区分材料，但数码相机提供高空间分辨率来描绘物体。在这两个示例中，可以单独或联合地考虑成像模态。在这一章中，我们讨论的数学方法，允许结合信息从几个成像模式，使多模态成像可以不仅仅是其组成部分的总和。
英文摘要：
Imaging with multiple modalities or multiple channels is becoming increasingly important for our modern society. A key tool for understanding and early diagnosis of cancer and dementia is PET-MR, a combined positron emission tomography and magnetic resonance imaging scanner which can simultaneously acquire functional and anatomical data. Similarly in remote sensing, while hyperspectral sensors may allow to characterise and distinguish materials, digital cameras offer high spatial resolution to delineate objects. In both of these examples, the imaging modalities can be considered individually or jointly. In this chapter we discuss mathematical approaches which allow to combine information from several imaging modalities so that multi-modality imaging can be more than just the sum of its components.
