ABSTRACT

Modern medicine widely use radiological techniques in many fields and areas, such as screening, diagnosis, clarifying the nature of changes in the internal organs. One of the leaders in diagnostic imaging methods, which are based on Χ-rays: roentgenogrphy and CT scan. These methods, theoretical basis of which have found their technical realization in the medicine in a relatively short period of time, and they quickly entered into the daily practice of professionals. But there is a survey methodology, theoretical foundations of which were nominated some earlier to the point when their practical possibility appears. And now they are gradually coming into practice ray diagnosticians, complementing the long-known technique of examination and in many ways allowing to make the diagnostic process more accurate, faster and better. One of these methods is a digital linear tomosynthesis. Occupying an intermediate position in the diagnostic range between radiography and computed tomography, tomosynthesis can be considered as an interesting alternative to these methods. As a software and hardware option of the radiographic system, tomosynthesis is possible to carry out research in information close to the CT scan, and in the cases with the presence of metal and surpassing such, at a much lower radiation dose to the patient, the lower cost of research, and at less time costs evaluation and processing.

Key words: linear digital tomosynthesis, digital radiography, radiology, flat panel detector, cancer screening
