本文利用衍射增强峰位成像技术研究全变态类蛹期粘虫的发育,得到了清晰的粘虫蛹的内部结构的相衬图像,清楚地观察到蛹发育的整个过程以及粘虫从幼虫到成虫部分器官、组织内细微结构的形成与演变,成像分辨率可达到5μm。
As a technique of X-ray phase contrast imaging, the diffraction enhanced imaging (DEI) attracts much interest due to its high resolution and contrast. The top images of DEI were used to study the growth of a complete metamorphic mythinma in the period of pupa. Clear images about the pupa structure were obtained. The entire growth process of the pupa was observed, including the evolvement of part of organs and tissues from larva to imago.
