Micro X-ray CT preclinical tomography system CT Lab HX

high-resolution

High-performance benchtop Rigaku CT Lab HX is a benchtop micro CT (computed tomography) scanner. The adjustable SOD (source-to-object distance) and SDD (source-to-detector distance) make this benchtop micro CT scanner flexible. It covers from 2.1 um voxel resolution in the high-resolution mode and 200 mm FOV (field of view) in the large FOV mode. The CT Lab HX is equipped with a 130 kV - 39 W high-power X-ray source. The X-ray source settings and X-ray filters are adjustable to optimize the X-ray energy to various sample materials and sizes. 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.
