对于医务工作者来说，人体软组织超声模型不仅用于超声诊断的准确性管理，还可辅助超声引导穿刺针和盲插导管的培训，对真实的患者没有风险。对于体模，需要超声特性和纹理来模拟人体软组织。申报体模由海藻酸钠、硫酸钙二水合物、磷酸三钠12水合物、甘油和水组成。该体模的传播速度、衰减系数、声阻抗和纹理与人体软组织的传播速度、衰减系数、声阻抗和纹理几乎相同。不需要昂贵的化学品和特殊设备。
For medical workers, ultrasound phantoms for human soft tissue are used not only for accuracy management of ultrasound diagnosis but also to aid ultrasound‐guided needle and blind catheter insertion training without risk to real patients. For the phantoms, ultrasound characteristics and a texture are required to mimic the human soft tissue. The proposed phantom was composed of sodium alginate, calcium sulfate dihydrate, trisodium phosphate 12‐hydrate, glycerol, and water. The propagation speed, attenuation coefficient, acoustic impedance, and texture of the proposed phantom were almost the same as those of human soft tissue. Expensive chemicals and special equipment are not required.
