Abstract
The purposes of this study are to improve the ultrasound resolution of various nylon and metallic mono-filament wires, therefore, it was tested that it analyze on nylon mono-filament wire of 0.1 mm in A Co.'s ultrasonic phantom and synthesis of C15 g tissue mimicking materials(TMM), analyze resolution of nylon and metallic mono-filament wires in water and TMM. The results obtained were summarized as follows: 1. Metallic mono-filament wire of 0.1 mm and nylon mono-filament wire of 0.12 mm, 180 denier showed that it cleared dot echo pattern. 2. Metallic and nylon mono-filament wire of 0.2 mm showed that it cleared comet tail echo by reverberation artifact. 3. Nylon and metallic mono-filament wire of 0.1 mm showed that it can used for dead zone and axial resolution test. 4. Nylon mono-filament wire compared with metallic mono-filament wire showed that it satisfy elasticity and construction. 5. Degree of hardness of na not changed mono-filament's echo textures.
초음파 Q/A팬텀은 조직등가물질(TMM)과 표적물질로 구성한다. 표적물질은 데드존, 거리분해능, 측분해능, 수직과 수평거리 정확성 등을 평가하는 모노필라멘트로 TMM과 조화를 이뤄 선명하게 나타나야 한다. 본 연구의 목적은 금속성 모노필라멘트와 나일론 모노필라멘트를 이용하여 TMM 내에서 최적의 해상력을 표현할 수 있는 선 표적물질을 얻기 위해 탈기수와 C15 g TMM을 합성하여 모노필라멘트를 설치하고 SONOACE 6000C
