Review of Methods to Control Patient Doses and Image Quality in Various CT Techniques

Herrnsdorf, Lars LU (2012) 10th International Conference on Medical Physics In Medical Physics in the Baltic States p.97-98
Abstract
Medical X-ray imaging is the largest source of radiation exposure to the population from artificial sources. Computed tomography (CT) contributes with 50-80 % of that radiation. About 660 000 CT examinations (2005) are done in Sweden every year. A CT examination gives a mean effective dose of 5 mSv, which is about 10 times higher than for a corresponding conventional X-ray investigation. This presentation describes earlier, current and future dosimetric and image quality analysis methods, necessary to correspond to the rapidly developing CT-techniques.
