Fundamentos físicos da formação de imagens em ultrassonografias

Abstract

n order to understand phenomena in the processes of image formation, it is necessary to have basic knowledge of physics. This monograph deals with studies of the physics of nuclear and electromagnetic radiations in the analysis of the interaction with matter, so we proceed to build necessary fundamentals of theoretical basis to understand the physical procedures performed in exams. Thus, the relations of energy absorbed in the processes of each examination were highlighted, the main effects acquired to the patient on contact with electromagnetic radiation, and the various electromagnetic applications, including medicine. For this, it was necessary to study since the discovery of X-rays, until the advance in the area in the treatment of diseases and applications in the health area, in the radiological and ultrasonic processes. The aim of this work is to understand the behaviors of the physico chemical analysis, the descriptions of the equipment necessary to carry out the examinations and their due functions. The objective of this work is to show and describe the relationships of physical knowledge to the evolution of applied medicine in diagnostic techniques and the importance of physics in the health area to aid in the treatment of diseases by diagnostic imaging.
