Abstract

As a result of measuring and evaluating 24 units of 10 types of medical ultrasonic equipment in Gwangju using the multipurpose ultrasonic phantom (ATS-539), all 24 units were 100% passed in the non-inspection area, vertical distance measurement, horizontal distance measurement, axial/side resolution, gray tone and dynamic range items. As a result of analyzing the ultrasonic phantom pass rate according to the number of years of use of ultrasonic equipment in Gwangju, this study derived that the service life of ultrasonic equipment is related to the equipment performance. As the coverage for ultrasonic inspection is gradually expanded starting with the upper abdominal ultrasound, it is time to further manage the quality of ultrasonic inspection. Therefore, in addition to the standard guidelines for performance measurement for abdominal inspection, research on equipment phantom measurement methods and standards that can be used in various ultrasonic inspection areas such as the neck and chest, which have recently become increasingly important in clinical practice, should be conducted at the same time. In addition, quality control standards should be legally established to maintain the optimal performance of ultrasonic imaging devices and to secure the appropriateness of images. In addition, ultrasound imaging devices should be classified as special medical equipment, and it is considered that the level of equipment should be consistently maintained through continuous management so that images beneficial to treatment can be obtained.

다목적 초음파 팬텀(ATS- 539)을 활용하여 광주지역 의료용 초음파장비 4개사, 10종류 24대를 대상으로 측정해 평가한 결과 합격 기준이 제시된 6개 항목에서 검사불능영역, 수직거리 측정, 수평거리 측정, 축/측 방향 해상도, 회색조와 동적 범위 항목에서 24대 모두 100% 합격이었다. 광주 지역 초음파장비의 사용연수에 따른 초음파 팬텀 합격률을 분석한 결과, 본 연구는 초음파장비의 사용 연한이 장비 성능과 관계가 있음을 도출하였다. 상복부 초음파를 시작으로 초음파 검사의 급여가 단계적으로 확대됨에 따라, 초음파 검사의 질 관리가 더욱 필요해진 시점이다. 따라서 복부용 검사를 위한 성능 측정 표준 지침뿐만 아니라, 최근 임상에서 중요성이 커지고 있는 경부 및 흉부 등 다양한 초음파 검사 영역에 활용할 수 있는 장비 팬텀 측정방법과 기준에 관한 연구도 병행되어야 한다. 또한, 초음파 영상 장치의 최적 성능 유지와 영상의 적절성 확보를 위해 품질 관리 기준이 법적으로 마련되어야 한다. 더불어, 초음파 영상 장치는 특수 의료 장비로 분류되어야 하며, 지속적인 관리로 장비의 수준을 일관되게 유지하여 진료에 유익한 영상을 얻을 수 있도록 해야 할 것으로 사료된다.
