The microCT world community map

Find out who’s doing what in microCT, or let the world know what you do!

There is now a dedicated microCT world community map page on the blog! Check it out to navigate through the microCT community. You’ll find scanner manufacturers, service providers, research labs, and more. Please, consider this as a living document that will take some time to be populated. If you are a professional who wants to be listed on the map, drop a comment on the dedicated page. Only companies / institutes / individuals who explicitly ask to be listed on the map will be included.

I hope you’ll find the map a useful tool and would be happy to receive any suggestion you may have.

MicroCT and QA

Over the past years, the topic of quality assurance (QA) has been a steady companion and although I might not necessarily like QA on f, there’s no doubt that thinking of negatively influencing variables of a working process is strengthening the awareness of potential issues and therefore still earns a +1 on g. Developing and implementing standard operating procedures (SOP)  is then the next step after the detailed risk assessment of a process and aims to standardize the findings of the expert, who is aware of all influencing variables and context-specific dependencies. And by fixing this approach into a written SOP, it can be ensured that the results obtained by following this procedure are consistent and don’t require the expert’s knowledge. Despite this rather short and simplified description of QA, it is probably common-sense that the benefit of eliminating (or at least consistently managing) critical issues of the process generally increases the quality of the results.

The history of microCT

The origins

The theoretical basis of Computed Tomography (CT) finds its origins in 1917, when the Austrian mathematician Johan Radon (16 December 1887 – 25 May 1956)  proved that an n-dimensional object can be reconstructed from its (n-1)-dimensional projections [1]. However, only in the second half of the century the mathematical basis for the actual CT image reconstruction was presented in two papers by Allan M. Cormack (Feb. 23, 1924 – May 7, 1998) [2, 3] in 1964 and 1965, respectively.

Maybe it is not as common and cheap as buying a microwave oven, but probably there are some of you who have thought about purchasing a microCT scanner, right?

Your questions: “Who are the scanner manufacturers?”, “Should I buy a scanner?”,  “What scanner ?”. This post will point you towards the information you need to make up your mind.

At the end the decision whether the investment is worthwhile depends on many things. What do you want to use microCT for? How often? Do you know how to operate a scanner? Do you have the right resources? And many more….
