Stationary sample, high-speed X-ray CT scanner
Ex-vivo and ultrafast in-situ compatible
Rigaku CT Lab GX is a micro-CT (computed tomography) scanner. The sample stays stationary as on a medical CT scanner, making it easy to mount samples with a complex shape or ones connected to in-situ devices. The combination of a high-power (90 kV – 8W or 130 kV – 39 W) X-ray source and the compact gantry geometry achieves ultrafast scans. A CT scan can be completed in 3.9 seconds at the top speed. The high-speed feature opens up the possibility of time-resolved (4D) CT experiments and CT quality inspection.
CT Lab GX Overview
When do I need high-speed?
You can say that the faster, the better when it comes to measurements. But especially when trying to capture a sample change that happens in a certain time period, the scan speed translates to the time resolution of in-situ, time-resolved, or 4D measurements. The high-speed also helps when you have many samples to run in a limited amount of time, for quality inspection or sample image archiving, for example.
Rigaku CT Lab GX can run a CT scan in 3.9 seconds at its top speed. Depending on the required time resolution or throughput, you can adjust the scan speed and image resolution up to an hour.
When do I need the stationary sample bed?
Sample mount can be tricky for CT measurements because you don’t want the sample to move during the scan and blur the image, and you might not want the sample holder, glue, or tape to be in the CT image. For in-situ experiments, the sample might be connected to other devices and need to stay still. The stationary sample bed solves all of those problems. On a gantry system, the sample stays still and the X-ray source and detector rotate around the sample. So there is no need to hold the sample or to worry about the sample moving during the scan.
Do I need to be an expert to run CT scans?
No, you don’t need to be an expert to run CT scans. Rigaku CT Lab GX has an easy-to-use simple user interface. You can simply select the area you want to image (FOV: field of view), scan time, and start the scan. You will be browsing the reconstructed CT cross-sections and 3D rendering images in less than a minute once the scan completes.
CT Lab GX Features
