Disturbing artifacts of radiodiagnostic modalities

This work gives information on machines used for diagnostic imaging aimed to disturbing scan artefacts of chosen device (CT, MR, USG). Radiology assistant work still more depends on technique which helps in examination. The machines used for clients´ examination are thanks to IT development still more complicated. They allow high-quality and precious images, give more possibilities of treatment ways, save the client. Operating this technique is the domain of radiology assistants. Development without restrain leads to period when operating staff will work more independently. It is necessary for the radiology assistant to manage all steps in examinations which are undergone. He has to keep radiation protection and the quality of the image result as well. The result of most diagnostic examination in radiology department is image information. Image results can be from various reasons changed or deformed in comparison with the reality. Such distorted images can lead up to mistaken or late diagnosis by the physician. Radiology assistant is the first specialist who must be able to judge whether the examination has been done correctly or to warn the physician of possible variation or image deformation. Moderation or suppression of artefacts in image results in examination is easy in some cases. Then it is enough to explain the process of examination to the client and to emphasize how important is to cooperate with the staff. In some cases is technically impossible to impact the manifestation of artefacts as it results from the principle of examination method, or because of high financial costs unbearable for the health institute. In my work I aimed to image artefacts of machines (CT, MR, USG) which can be met in common clinical practice. I tried to document these image artefacts in common running. Part of my work is to describe the causes of artefacts appearance and the way how to avoid or remove their manifestation
