Purpose: The purpose of this study was to identify the quality control status of ultrasonographic equipment, to evaluate the performance of such equipment in upper class general hospitals and common general hospitals in Chonrabuk?]do. For the purpose of this study, the equipment was evaluated using ATS?]539 multipurpose phantom with 8 items to identify the appropriateness of the equipment. Subjects and Method: For three months from November in 2011 to January in 2012, the status of 31 ultrasonographic equipment in 2 upper class general hospitals and 12 general hospitals were identified and then evaluated for the performance. The measurement items were Dead zone, Vertical measurement, Horizontal measurement, Axial/lateral resolution, Focal zone, Sensitivity (maximum depth of penetration), Functional resolution definition and fill?]in, and Gray scale and dynamic range. Classifying the appropriateness standards using three items such as Dead zone, Axial/lateral resolution, and Gray scale and dynamic range, they were analyzed with clinical characteristics. Results: It was found that 80.6% of ultrasonographic equipment was appropriate. 16.1% was evaluated inappropriate, because it did not distinguish the target of axial/lateral resolution, which included lap top type portable ultrasonographic equipment. Ultrasonographic equipment evaluated inappropriate in dead zone was over 7 years old. Conclusion: According to this study, 19.4% of non?]conforming ultrasonographic equipment was found in upper class general hospitals and common general hospitals in Chonrabuk?]do. The major reasons of non?]conformity were age or low grade. Aged and low grade equipment should be removed to upgrade the medical service quality. Through regular quality control of ultrasonographic equipment, initial defects of equipment should be corrected, the use of inappropriate equipment should be prevented and ultimately the quality of clinical image should be enhanced. Through these efforts, positive effects such as protection of health right and efficient use of resources can be expected.
