美国CIRS 057A三维腹部体模，CIRS 057A三维腹部模体，CIRS 057A腹部模体概述：

The CIRS Triple Modality 3D Abdominal Phantom is constructed of a self-healing formulation of Zerdine?(1) that allows multiple biopsy insertions with minimal needle tracking, and is ideal for demonstrating image-guided navigation technologies.

Abdominal imaging is useful for diagnosing disease and monitoring treatments.??The Model 057A is representative of a small adult abdomen and can be imaged under CT, MR and ultrasound.??This feature makes the phantom a useful tool for applications such as image fusion studies; imaging protocol developments; scan technique training; and system testing, validation and demonstration.

The Model 057A simulates the abdomen from approximately the thorax vertebrae (T9T10) to the lumbar vertebrae (L2L3) using simplified anthropomorphic geometry.??The materials provide contrast between the structures under CT, MR and ultrasound. The solid polymer background gel will not leak when punctured.*

Internal structures include the liver, the portal vein, two partial kidneys, a partial lung, the abdominal aorta, the vena cava, a simulated spine and six ribs. The liver has six lesions and the kidneys each have one lesion.??A muscle la[x]yer and outside fat la[x]yer surround these structures and plastic end caps make the phantom durable enough for extended scanning.?Blood vessels have CT contrast added to provide enhanced auto registration in image fusion applications

The Phantom includes a foam lined hard carry case. To accommodate image fusion techniques, CIRS can offer value-added options and services such as phantom specific CMM, reference CT or MRI data sets, attachment of customer specific registration devices and inclusion of special point markers.

CIRS的三模三维腹部幻影是由Zerdine?(1)的自愈制剂构建的，该制剂允许多个活检点插入，同时zui小化针的跟踪，是演示图像导航技术的理想选择。

腹部显像对疾病的诊断和监测治疗是很有用的。057A型是一个小的成人腹部的代表，可以在CT, MR和超声波下成像。该特性使得phantom成为图像融合研究等应用领域的一个有用工具;成像协议发展;扫描技术培训;以及系统测试、验证和演示。

057A模型使用简化的拟人几何图形来模拟从近似胸椎骨(T9T10)到腰椎(L2L3)的腹部。这些材料提供了CT、MR和超声下结构的对比。固体聚合物本底凝胶穿刺时不漏*

内部结构包括肝脏、门静脉、两个部分肾脏、一个部分肺、腹主动脉、腔静脉、模拟脊椎和六根肋骨。肝脏有六个病变，肾脏各有一个病变。肌肉层和外部脂肪层环绕这些结构和塑料端盖使幻影足够持久的扩展扫描。血管增加了CT对比度，增强了图像融合应用中的自动配准

幻影包括一个泡沫内衬硬手提箱。为了适应图像融合技术，CIRS可以提供增值选项和服务，如幻影特定CMM、参考CT或MRI数据集、附加客户特定的注册设备和包含特殊点标记。
