Nikola Tesla was an ingenious and briliant scintifist which contributed to the science and technology prosperity of the world. Nikola Tesla discovered high frequency oscillator 1891 year, and afterwards, single electrode X-ray tube without target electrode, electron (?particles charged with electricity?), Bremsstrahlung or ?breaking radiation? or ?very special radiation? (X-radiation) in 1892 year, biological hazards of X-rays, and more about 700 inventions, and 112 patents. Tesla's research work in the field of X-rays was stopped in 1895 because burned in his laboratory. When W. C. R?ntgen 1895, recognition X-rays, Tesla restored his work on this field and sent R?ntgen a telegram with congratilations and R?ntgen shows obtained with X-ray tubes which operated with high frequency currents. Tesla discovered many secret of nature.

Introduction. The interest in Nikola Tesla, a scientist, physicist, engineer and inventor, is constantly growing. In the millennia-long history of human civilization, it is almost impossible to find another person whose life and work has been under so much scrutiny of such a wide range of researchers, medical professionals included. Although Tesla was not primarily dedicated to biomedical research, his work significantly contributed to the development of radiology, and high frequency electrotherapy. This paper deals with the impact of Tesla?s work on the development of a new medical branch - radiology. Nikola Tesla and the Discovery of X-ray radiation. Tesla pioneered the use of X-rays for medical purposes, practically laying the foundations of radiology. Namely, since 1887, Tesla periodically experimented with X-rays, at that time still unknown and unnamed, which he called "shadowgraphs". Moreover, at the end of 1894, he conducted extensive research focusing on X-rays, but unfortunately it was interrupted after the fire burning down his laboratory in 1895. In 1896 and 1897, Tesla published ten papers on the biologic effects of X-ray radiation. All his studies on X-rays were experimental. During 1896 and 1897, Tesla continued improving X-ray devices. Apart from this, Tesla was the first to point out the harmful effects of exposure to X-ray radiation on human body. Conclusion. Nikola Tesla was a visionary genius of the future. Tesla?s pioneer steps, made more than a century ago in the domain of radiology, are still being used today.

To facilitate orientation in time, some selected events will be briefly presented. Approximately five hundred years ago, Columbus discovered America. One hundred years ago, on November 8th, 1895, Wilhelm Conrad R6ntgen discovered the X-rays which in the German language are called after him. In 1912 Max von Laue conducted the first X-ray diffraction experiment. In 1892 Richard Seifert Sr. founded the Electrotechnical Plant in Hamburg. After World War I (1914-1918) the company founder gradually handed the firm over to his son Richard Seifert Jr. After his son had completed studies in physics and electrical engineering he conducted pioneering experiments on the application of X-rays in science and technology. From the very beginning, X-ray equipment was produced in the three fields of medicine, science and technology. It was only ten years after World War II (1939-1945) that the line of medical equipment was discontinued and the daughter [1] as a member of the third generation gradually took over executive management tasks.

The disease caused by the new coronavirus (COVID-19) has been plaguing the world for months and the number of cases are growing more rapidly as the days go by. Therefore, finding a way to identify who has the causative virus is impressive, in order to find a way to stop its proliferation. In this paper, a complete and applied study of convolutional support machines will be presented to classify patients infected with COVID-19 using X-ray data and comparing them with traditional convolutional neural network (CNN). Based on the fitted models, it was possible to observe that the convolutional support vector machine with the polynomial kernel (CSVMPol) has a better predictive performance. In addition to the results obtained based on real images, the behavior of the models studied was observed through simulated images, where it was possible to observe the advantages of support vector machine (SVM) models.
