MicroCT and X-ray microscope

You can make service requests for using our microCT and X-ray microscope for academic or commercial purpose. Learn about the microCT and X-Ray services we offer and how to request service.

Requesting services of the MicroCT and X-Ray microscopes

  • Make a service request through our service request website to start requesting service of the MicroCT and X-ray microscopes.

You will need to create an account on the website if you haven't used the service before. Please follow the instructions in that website for help on creating an account. If you need further assistance, please contact our technical manager (see below.)

Via the service request portal, a user can submit a project request to be evaluated by the technical manager. This will involve reviewing the scope of the project, provide an estimation of feasibility, cost and time required.

More information about our services, opening hours and hourly rates are available through the portal once you have logged in.

Our equipment and services

We provide professional service on all aspects of imaging and specimen preparation. We are equipped with a SkyScan 1172 micro computer tomography instrument, and a new generation SkyScan 1272 instrument capable of sub-micron pixel resolution.

For more information on our services, including costs and opening hours, please see our pamphlet and the microCT and X-ray information page.

Here are some examples of the scans we have created in the past:

What is MicroCT and X-Ray microscopy?

MicroCT and X-ray microscope is an imaging modality to non-destructively obtain 2D & 3D structural information & volumetric analysis from small samples. The samples can originate from biological, material, geological and engineering scources.

MicroCT is a high resolution X-ray computed tomography. It results in a three dimensional image of X-ray attenuation throughout the sample.

In most cases samples for microCT require no special preparation as contrast is obtained due to the differing absorption of X-rays. However for soft tissue biological samples staining is required and there are simple methods available.

Magnification is achieved geometrically by the relationship of the sample & camera. Resolution and field of view depend on each other as well as being sample size dependent. Thus imaging at high magnification (0.5 ┬Ám pixels) has a field of view of 2.4 x 1.6 mm and a sample diameter of less than 2 mm.

MicroCT can also be used as an X-ray microscope to quickly obtain 2D structural and density differences in thin samples.

MicroCT is not a quick technique as the acquisition of thousands of individual projections can take hours per sample and is highly dependent on spatial resolution requirements. It is data and computationally intensive thus requiring Tb of storage and high end computing hardware.

MicroCT is capable of dynamic experiments using tension / compression and cooling / heating stages.

An operator is available to run samples and training can be given to users who have long term requirements.

There are fees associated with use of the instruments, services offered and operator time.
