What is x-ray micro tomography?
X-ray micro tomography is a non-destructive imaging technique that provides high-resolution 3D images of samples.
How does sample preparation differ for mineralized and non-mineralized tissues?
Mineralized tissues require sealing in tight containers, while non-mineralized tissues have different preparation protocols.
What are the advantages of using x-ray micro tomography over other imaging methods?
It offers higher resolution and the ability to visualize thick volumes without destructive sampling.
How long does the imaging process take?
Imaging can take several hours depending on the sample and desired resolution.
What software can be used for analyzing the images?
Software such as ImageJ or Fiji can be used to analyze large image files generated by the imaging process.
