CT Lab HX

How do I achieve high resolution?

Rigaku CT Lab HX uses the cone-beam geometry. This geometry uses the X-ray beam divergence to magnify the sample image. The magnification factor is determined by the ratio of SOD (source-to-object distance) and SDD (source-to-detector distance). So to achieve high resolution, you can increase the SDD and/or decrease SOD. CT Lab HX has the flexibility to do them both in its compact design.

With the long SDD and short SOD settings, you can achieve 2.1 um voxel resolution (~ 5 um spatial resolution) on the CT Lab HX. This resolution can reveal micro cracks, voids, fibers in composites, etc.

How do I achieve 200 mm FOV?

The FOV (field of view) you can cover in one scan is limited by the size of the detector. However, the offset scan mode doubles the effective detector width to cover a wide FOV without having to change the detector. Rigaku CT Lab HX utilizes this scan mode to achieve 200 mm FOV without having to change the detector or compromising its compact system size.

The 200 mm FOV enables a scan of an entire smartphone, 3D printed objects, fruits, etc.

Do I need a large CT scanner to cover both high-resolution and large FOV?

No, you don't need a large floor standing type CT scanner to cover a wide range of resolution and FOV for most samples under 200 mm in size and made of elements lighter than aluminum.

Rigaku CT Lab HX has the flexibility to change both SOD and SDD to cover from 2.1 um to about 100 um voxel resolution. And the offset scan mode can cover 200 mm FOV.

This flexible and compact design makes CT Lab HX an affordable research-grade micro CT scanner ideal for materials science imaging centers.
