ETU “LETI” researchers developed a small-sized tomograph with wide diagnostic capabilities
ETU “LETI” researchers developed a portable tomograph for studying the structure of various objects, as well as small laboratory animals. The technology surpasses foreign counterparts in several metrics.
A new class mini-tomograph will make it possible to solve most of the issues in science and industry that are feasible only for large-sized foreign x-ray inspection systems. Its main advantages are small dimensions, high information content, low power consumption, and affordable price.
“We have developed a complete set of technical equipment for high-resolution X-ray tomography, including specialized software. The technology uses a microfocus tube, which allows for high image sharpness and providing an image of the object in very good quality."
A portable device developed by ETU “LETI” researchers weighs no more than 250 kg, which facilitates its transportation. The mini-tomograph includes an X-ray proof camera with dimensions of 1100×670×550 mm. With it, one can study objects up to 210×250×250 mm in size. Another difference between the new device and the medical tomograph is the shift in the source and receiver paradigm.
“Typically, the object under inspection is located inside the tomograph, and the source and receiver system rotates around it. In our portable tomograph, the opposite is true: we rotate the fixed object, and the elements of the system are motionless relative to each other,” Nikolai Potrakhov explained.
ETU “LETI” specialists not only used original technical solutions, they also developed a special computer program for the rendering of three-dimensional images.
“Unlike conventional x-ray photography, the image is not formed on a film or on something else, but reconstructed. The computer allows you to get information, draw the entire volume of the object, and then study it from any angle.”
Three-dimensional visualization of objects and their internal structure is currently one of the most trendy and effective research methods. The diagnostic capabilities of the miniature tomograph are in demand, for example, during a fire cause investigation. A large number of fires occur annually in the world. For each of them, experts investigate the evidence from the scene. The invention of ETU “LETI” researchers will help experts quickly identify a source of ignition and accurately determine its cause. One unique mini-tomograph is already successfully operating in the fire investigation laboratory of the Ministry of Emergencies of Russia in St. Petersburg.
The second device of ETU “LETI” researchers is working in the interests of the museums of the Northern capital. It helps to research various objects - bones and art objects, determine their authenticity, choose the right restoration technique, and much more.
Another area of application for portable tomography is preclinical studies of drugs to verify their safety, quality, and effectiveness.
