Since off-axis wander results in images which have astigmatism when the prism is placed in a converging beam, Glan types have slightly better imaging qualities than Nicla types.
因为当棱镜置于会聚光束中时，离轴漂移造成有像散的像，格兰型棱镜的成像质量比尼·科尔型略好。

Helium ion microscopy (HIM) offers the highest spatial resolution surface imaging of any scanning beam method, as well as extremely high surface sensitivity.
氦离子显微镜能够提供所有扫描射线法中最高空间分辨率的表面图像，以及极高的表面灵敏度。

Dual-energy CT has also been shown to allow for improvements in image quality and reduction in artifacts such as beam hardening that have traditionally limited CT perfusion imaging(101).
