FOVEA: tomography a horse through the eye of a needle

X-ray tomography is one of two (along with MRI) the most famous ways to β€œ look inside ” opaque objects. In medicine, it is an instrument of clinical monitoring and a means of therapy, in the industry it helps to control technological processes , in customs - to find something that someone would prefer to hide. This technology in our country is developing in house at the world level. But that's not the only reason why we at Smart Engines write about tomography so often. We are scientists and inventors, and tomography is an inexhaustible source of problems and problems that need to be solved (we have already written about imperfect detectors and broadband radiation). Today we will tell you what to do if the object of investigation does not fit into the tomograph. This is how, for example, British scientists study a horse in a zoo. It is possible to place the horse's head in the gantry, but with the rest, things are more complicated. An example is not very serious, but vital. Those who worked in the laboratory do not laugh at the zoo. Looking under the cat you will find out how it turns out that physicists do not fit a centimeter sample into a kilometer tomograph, and how computational mathematicians can help here.





Our tomographic mascot inspires specialists with literally all of its mmm ... details. So with general geometric shapes, everything is very successful. Gantry to her is like a hula-hoop: you can scan from top to bottom, even from bottom to top.
