Information Technology in Medical Diagnostics
For many centuries, people have tried to learn about the state of their health. Initially, in the pre-technological period, they had to rely only on their senses. Then there were simple tools to help the human senses. The discovery of X-rays, which allowed people to look “inside” the body, turned out to be a major breakthrough. Contemporary medical diagnostics is increasingly being assisted by information technology that allows, for example, thorough image tissue analysis or pathology differentiation. They also allow very early preventive diagnostics. Influenced by information technology, “classic” diagnostic techniques change and new ones arise.
Information Technology in Medical Diagnostics presents selected and extended conference papers from Polish, Ukrainian and Kazakh scientists. They address problems of the application of new methods of image processing for analysis of medical images, new methods of classification of medical data as well as new medical imaging methods. Some of the presented technologies are inspired by the functioning of living organisms.
Information Technology in Medical Diagnostics is of interest not only to academics and engineers, but also to professionals involved in biomedical engineering, and seeking for solutions for issues that cannot be solved with the help of “traditional” technologies.

Biography
Waldemar Wójcik was born in Poland, 1949. He is Director of the Institute of Electronics and Information Technology, former longtime dean of the Faculty of Electrical Engineering and Computer Science at Lublin University of Technology. Doctor Honoris Causa of five universities in Ukraine and Kazakhstan. He obtained his Ph.D. in 1985 at the Lublin University of Technology, and D.Sc. in 2002 at the National University Lviv Polytechnic, Ukraine. In 2009 he obtained a title of professor granted by the President of Poland. In his research he mainly deals with process control, optoelectronics, digital data analysis and also heat processes or solid state physics. Particular attention is paid to the use optoelectronic technology in the monitoring and diagnostics of thermal processes. He is a member of Optoelectronics Section of the Committee of Electronics and Telecommunications of the Polish Academy of Sciences; Metrology Section of the committee of Metrology and Scientific Equipment of the Polish Academy of Sciences and many other scientific organisations of Poland as well as Europe and Asia. In total, he has published 53 books, over 400 papers, and authored several patents. He is also a member of the editorial board of numerous international and national scientific and technical journals.
Andrzej Smolarz (Ph.D., D.Sc. Eng.) graduated from Lublin University of Technology Faculty of Electrical Engineering. During 28 years of professional work he has reached the position of associated professor at his Alma Mater in the Institute of Electronics and Information Technology.
