研制了一种基于光学读出玻璃气体电子倍增器的软X射线CT扫描仪探测器。软X射线成像(<20kev)提供低Z元素的高对比度图像,例如软组织。我们用高分辨率气体探测器和3D打印机对Low-Z物体的三维(3D)拷贝进行建模。该探测器用于获取高分辨率图像以重建3D计算机断层扫描(CT)图像。作为例子,以高对比度重建了黄蜂的精细三维X射线CT图像。3D CT数据被转换成3D计算机自动设计数据,并用商业3D打印机打印扫描对象的副本。总体而言,这项工作展示了气体探测器、快速和精确的软X射线3D扫描以及软组织建模的新用途。
A new detector, based on an optical-readout glass gas electron multiplier was developed for a soft X-ray CT scanner. Soft X-ray imaging (< 20 keV) provides high-contrast images of low-Z elements, such as soft tissues. We model a three-dimensional (3D) copy of a low-Z object with a high-resolution gaseous detector and a 3D printer. The detector was used to acquire high-resolution images to reconstruct a 3D computed tomography (CT) image. As an example, a fine 3D X-ray CT image of a hornet was reconstructed with high contrast. The 3D CT data were converted into 3D computer-automated design data, and a copy of the scanned object was printed with a commercial 3D printer. Overall, this work demonstrates a new use of gaseous detectors, rapid and precise soft X-ray 3D scanning, and modeling of soft tissues.
