QRM QRM-MicroBar测试卡,QRM-MicroBar测试模体,Micro-CT高分辨率测试卡 技术参数:
内含两个3mm×3mm硅质芯片,分别水平和垂直安装,芯片上刻有条状(沟槽)和点状图样,度规格为:1μm,2μm,3μm,4μm,5μm,6μm,7μm,8μm,9μm,10μm.
作为我们流行的MicroCT-BarPattern-Phantom的进一步发展,我们现在推出BarPattern-NANO!
QRM QRM-MicroBar测试卡,QRM-MicroBar测试模体,Micro-CT高分辨率测试卡易于使用的幻像提供了两个硅芯片,它们垂直对齐并放置在坚固的塑料支架上。
两种3 x 3mm²的芯片都具有数个线和点图案,分别代表线和点的宽度为1至10 µm。
此外,在芯片上还放置了锯齿状边缘(L)和西门子星(放射状星)。
芯片上的不同结构以这种方式布置在芯片上,从而可以通过一次测量在图像/芯片的中心以及外围区域中确定空间分辨率。
芯片上的线型和点型:3 x 3mm²
结构的深度在5和15 µm之间变化。

As a further development of our popular MicroCT-BarPattern-Phantom we now present the BarPattern-NANO!
The easy and convenient to use phantom provides two silicon chips, perpendicularly aligned and placed on a solid plastic support.
Both 3 x 3 mm² chips exhibit several line and point pattern representing lines and points of 1 to 10 µm width.
In addition a slented edge (L) and a Siemens-star (actinomorphic star) are also placed on the chip.
The different structures on the chip are arranged in such a way over the chip, that spatial resolution can be determined in the center as well as in the peripheral regions of the image/chip with a single measurement.
Line- and Pointpattern on the chip: 3 x 3 mm²
The depth of the structures varies within 5 and 15 µm.
