摘要

我们开发了一种x射线针孔相机，使用的是只发射x射线的放射性同位素源。我们使用带有幻影样品的55Fe源来研究该系统的性能。然后，我们将其应用于研究55Fe示踪剂在日本芥菜菠菜中的运动。我们获得了菠菜样品中55Fe示踪剂的x射线图像，发现55Fe在植物中积累。

An X-ray pinhole camera using metallic radioisotopes emitting only characteristic X-rays

We developed an X-ray pinhole camera using a radio-isotope source that emits only X-rays.We investigated the performance of this system using a 55Fe source with phantom samples. We then applied it to investigate the movement of a 55Fe tracer in Japanese mustard spinach. We obtained X-ray images of the 55Fe tracer in the spinach samples, and found that 55Fe accumulated in the plant.
