120 years since the discovery of X-rays

This paper is intended to celebrate the 120th anniversary of the discovery of X-rays. X-rays (Roentgen-rays) were discovered on the 8th of November, 1895 by the German physicist Wilhelm Conrad Roentgen. Fifty days after the discovery of X-ray, on December 28, 1895, Wilhelm Conrad Roentgen published a paper about the discovery of X-rays - ?On a new kind of rays? (Wilhelm Conrad Roentgen: ?ber eine neue Art von Strahlen. In: Sitzungsberichte der W?rzburger Physik.-Medic.-Gesellschaft. 1895.). Therefore, the date of 28th of December, 1895 was taken as the date of X-rays discovery. This paper describes the work of Wilhelm Conrad Roentgen, Nikola Tesla, Mihajlo Pupin and Maria Sklodowska-Curie about the nature of X-rays. The fantastic four - Wilhelm Conrad Roentgen, Nikola Tesla, Mihajlo Idvorski Pupin and Maria Sklodowska-Curie set the foundation of radiology with their discovery and study of X-rays. Five years after the discovery of X-rays, in 1900, Dr Avram Vinaver had the first X-ray machine installed in Sabac, in Serbia at the time when many developed countries did not have an X-ray machine and thus set the foundation of radiology in Serbia.

Terahertz Ray Imaging: A New Ray of Hope in Imaging Science

Imaging technology is becoming increasingly prevalent in our society.Even though there were many successful imaging modalities ever since the advent of roentgen rays, they all have their shortcomings. And imaging of dental tissue had always been a challenge in imaging science due to the various layers which differ in physical and chemical and structural properties. Considerable improvisations of existing techniques and new research activities.
