Welcome to the first episode released for Covalent Academy’s Advancements in Instrumentation webinar series. This series will feature expert speakers from Covalent’s corporate instrument partners, and will highlight the latest innovations in analytical technologies.
This webinar is led by Rigaku Americas Corp.’s Director of X-ray Imaging, Aya Takase, who specializes in developing new analytical and measurement methods for X-ray tools. She will introduce the key ideas behind one of the most exciting new technologies in X-ray metrology: microscale x-ray computed tomography (CT).
The webinar will introduce some common challenges and practical considerations for X-ray-CT operation, go over instrumentation options and discuss case studies and advances in technique development.
This Webinar Will Answer:
- What is X-ray Computed Tomography?
- Why is X-ray Computed Tomography valuable?
- What kinds of analysis can X-ray Computed Tomography perform?
- What measurements are possible with a Micro-CT system?
- How is X-ray Computed Tomography used in industry?
Frequently Asked Questions
I found out about this webinar through an email from Rigaku sales rep this morning. Is there a central webpage with upcoming webinars? My coworkers and students would be interested and I would like to spread the word.
If you join our Covalent Community you will have access to webinar, slides and Q&A for our whole series and if you co-workers and student sign up they will be on our mailing list for future webinars. We are currently doing 1 per week at this time. You can also visit www.rigaku.com/webinars for Rigaku’s upcoming webinars and www.rigaku.
com/webinars/x-ray_ct_introduction for the recording of X-ray CT related webinars.
Is elemental identification possible?
You can do X-ray fluorescence tomography to obtain 3D elemental distribution. Note that this technique requires synchrotron radiation, and the spatial resolution tends to be limited.
Can you comment on imaging soft tissue and the use of contrastenhancing techniques, including iodine staining?
We will answer this offline. It will be part of the Q&A session we post.
What is the minimum energy of the Lab Hx system at CM?
The minimum applied voltage is 30 kV, which has a peak around 15-20 keV.
Can you use x-ray absorption edges and x-ray diffraction to enhance the imaging?
Yes, you can use absorption edges to enhance contrast. Diffraction is used for a different purpose. Diffraction tomography is used to map crystal orientation of each grain/crystallite in 3D. It is a 3D version of EBSD. The calculation for this analysis is
complex, and I have seen this work only on a single-phase cubic or hexagonal material. Most of the experiments are done using synchrotron radiation.
Is it possible to get analytical data, I have seen this using X-ray diffraction patterns (Cubic structures)?
Diffraction tomography can be used to map crystal orientation of each grain/crystallite in 3D. It is a 3D version of EBSD.
