摘要
X 射线成像是对人体内部和其他不透明样本进行非侵入式可视化的一种流行技术。在大多数商用 X 射线模式中,图像是通过测量穿过相关物体的 X 射线形成的。然而,尽管散射辐射可能提供有关物体的额外信息,但由于其固有的导致模糊的倾向,往往被忽视。因此,传统的成像模式无法测量或利用这些宝贵的数据。与此相反,我们提出并通过实验演示了一种高分辨率的 X 射线计算机断层扫描(CT)技术,该技术通过利用计算鬼影成像(CGI)来测量散射辐射。我们的研究表明,该方法的分辨率可超过 500 微米,比基于散射辐射的 X 射线成像模式的典型分辨率高出约一个数量级。我们的研究揭示了一种将散射辐射数据纳入 CT 扫描的前景广阔的技术,它可以提高图像对比度和分辨率,同时最大限度地减少对患者的辐射照射。我们的研究结果表明,我们的技术代表了医疗和工业成像领域的一大进步,有可能提高成像诊断程序的准确性和安全性。X 射线计算机断层扫描是一种广泛应用的非侵入性人体内部成像技术。A. Ben Yahuda 及其同事报告了一种将散射辐射数据纳入计算机断层扫描的技术,以提高图像分辨率并最大限度地减少对患者的辐射照射。
High-resolution computed tomography with scattered X-ray radiation and a single pixel detector
X-ray imaging is a prevalent technique for non-invasively visualizing the interior of the human body and other opaque samples. In most commercial X-ray modalities, an image is formed by measuring the X-rays that pass through the object of interest. However, despite the potential of scattered radiation to provide additional information about the object, it is often disregarded due to its inherent tendency to cause blurring. Consequently, conventional imaging modalities do not measure or utilize these valuable data. In contrast, we propose and experimentally demonstrate a high resolution technique for X-ray computed tomography (CT) that measures scattered radiation by exploiting computational ghost imaging (CGI). We show that the resolution of our method can exceed 500 µm, which is approximately an order of magnitude higher than the typical resolution of X-ray imaging modalities based on scattered radiation. Our research reveals a promising technique for incorporating scattered radiation data in CT scans to improve image contrast and resolution while minimizing radiation exposure for patients. The findings of our study suggest that our technique could represent a significant advancement in the fields of medical and industrial imaging, with the potential to enhance the accuracy and safety of diagnostic imaging procedures. X-ray computed tomography is a widely used technique for non-invasively visualizing the interior of the human body. A. Ben Yahuda and colleagues report a technique for incorporating scattered radiation data in Computed Tomography scans to improve image resolution and minimize radiation exposure for patients.
