Implementation of new technologies in medicine is historically connected via a collaboration between physicians and physicists. Through many of the new medicine methods were famously in the spotlight, the technology and physics remained hidden in the background. Interestingly. it is true that at the outset many of these new technologies were implemented into medical practice without any proper study of its physical basis, risk assessment or appropriate research (an example of this is radiotherapeutics use of X-rays within 6 months after their discovery). Current state-of-the-art of medicine requires a close cooperation between physicians and clinician technologists, and in the case of the use of ionizing radiation, also medical physicists. Correct cooperation is the basis of up-to-date medical care, which now more than ever before, is a multidisciplinary branch., Pavel Solný., and Obsahuje bibliografii
