Tomography with Soft and Hard X Rays at the ALS
The internal structure of an object can be visualized in 3 Dimensions using x-ray tomography. By using synchrotrons as a source of x-rays, it is now possibly to obtain tomographic images of objects spanning an unprecedented range of sizes and compositions. X-ray photons with energies in the 6kV to 50kV+ range, it is possible to image the internal structure of ‘hard’ materials, such as samples of concrete, or very dense biological materials such as bones or teeth. X-ray photons at the ‘softer end’ of the spectrum can be used to image small objects comprised of ‘soft matter’, such as an individual biological cells.
This workshop will be a forum to discuss the current ‘state of the art’ in x-ray tomography, as practiced at the ALS and at other synchrotron light sources. The workshop will also include presentation and discussion of some of the latest techniques and philosophies for data collection, and generating tomographic reconstructions. The day long workshop will be split into four topics:
- Tomography at the ALS
- Tomography techniques
- Tomography at other synchrotrons
- General Tomography
At the end of the workshop, there will be an opportunity to tour the hard and soft x-ray tomography facilities at the ALS.
