[Clinical control of the quality of dynamic echography].
The performances of 4 real-time scanners (2 mechanical sector scanners and 2 linear electronic scanners) have been tested. The clinical test used was the examination of liver, gallbladder and biliary tract and in other circumstances the examination of kidney and breast. The quality of the scanners has been judged on the ground of four parameters: the diagnostic quality of the image (DQI) the overall quality of the image (OQI), the efficiency of the exploration (EE) and feasibility of use (FU). The ideal conditions of use for each technology are described and the authors emphasize the impact of improved technology on the quality of the ultrasonographic scanners.
