Spatial Coherence Effect Tomography for Biological Structural Analysis

9361730 Aye PoC提出了一种全新的层析成像方法，其中3-D对象的记录和重建在2-D切片中自动完成，无需显著的计算机辅助并且具有非常高的空间分辨率。这一新技术是基于减少相干干涉法，将被称为空间相干效应层析成像(SCET)。SCET克服了传统全息和层析方法的局限性。以前的3-D层析成像尝试通常涉及2-D投影图像和大量使用计算机进行数据处理和显示，因此降低了空间分辨率。虽然全息成像可以提供高分辨率，但它缺乏内在的层析解释。所提出的方法基于使用具有非常短的时间相干长度的辐射的全息记录，这可以克服使用这种源的技术中的主要缺陷，同时仍然保留了层析和全息术两者的优点。此外，该方法简单有效，因为它可以在单个记录中提供对象切片的高(空间)分辨率图像的连续体。这一新系统将产生低成本、高分辨率的断层成像，用于生物结构分析以及其他无损评估(NDE)应用。***

9361730 Aye POC proposes an entirely new approach to tomography in which recording and reconstruction of the 3-D object is done in 2-D slices automatically, without significant computer assistance and with very high spatial resolution. This new process is based on reduced coherence interferometry and will be called Spatial Coherence Effect Tomography (SCET). SCET overcomes the limitations of both classical holographic and tomographic approaches. Previous attempts at 3-D tomographic imaging usually involved 2-D projection images and the heavy use of computers for data processing and display, thus reducing spatial resolution. Although holographic imaging can provide high resolution, it lacks an intrinsic tomographic interpretation. The proposed method is based on holographic recording using radiation with very short temporal coherence length which can overcome major drawbacks in techniques using such sources, e.g., x-ray lasers, while still preserving the advantages of both tomography and holography. Moreover, the method is simple and efficient because it can provide a continuum of high (spatial) resolution images of object slices in a single recording. This new system will produce low-cost, high-resolution tomographic imaging for biological structural analysis as well as other non-destructive-evaluation (NDE) applications. ***
