온도분포 가시화를 위한 초음파 모의 생체매질의 제안 및 그 특성에 관한 연구

Abstract

Abstract

Even though the tissue mimicking phantom could be useful method in medical ultrasonic field, it is hard to show the thermal distribution caused by ultrasound in the phantom. To solve this problem, we fabricated the tissue mimicking phantoms to visualize the thermal distribution caused by the ultrasound using agar, sugar, and Thermo Chromic Micro-capsule (TCM). To confirm the effectiveness of the phantom, the focusing ultrasound was radiated from a concave type ultrasound transducer. The temperature distribution in the tissue mimicking phantom was confirmed according to the ultrasonic radiation time. The acoustic characteristics of the phantom was also investigated according to the concentration of the sugar, the agar, and the thermo chromic particles. From this study, it is confirmed that the tissue mimicking phantom showing thermal distribution could be fabricated by adjustment of the ingredient ratio of the phantom.
