Ultrasound phantoms are commonly used to assess the performance of ultrasound systems and ensure their proper functionality, in addition to providing opportunities for medical training. However, Focused Assessment with Sonography for Trauma (FAST) phantoms, in particular, are prohibitively expensive and procedure specific. This work explores the use of additive manufacturing to fabricate a patient-specific, full-scale torso ultrasound phantom. Phantom geometry was derived from anonymized computed tomography scans and segments into discrete organs. The digital organs (torso, skeleton, liver, spleen) were 3-D printed and used as castable molds for producing their respective body features. These organs were integrated with artificial hemorrhages to produce a realistic training tool for FAST scans. The resulting phantom is low in cost, has a verified shelf-life of at least 1 y and was positively reviewed by a trauma and emergency radiologist for its ability to provide accurate geometric and ultrasound information.

除了提供医疗培训机会外，超声模体通常用于评估超声系统的性能并确保其正常功能。然而，创伤超声 (FAST) 体模的聚焦评估尤其昂贵且特定于程序。这项工作探索了使用增材制造来制造特定于患者的全尺寸躯干超声模型。幻影几何来自匿名计算机断层扫描和分割成离散器官。数字器官（躯干、骨骼、肝脏、脾脏）被 3D 打印并用作可浇注模具，以产生各自的身体特征。这些器官与人工出血相结合，为 FAST 扫描提供了一种逼真的训练工具。由此产生的幻影成本低，
