美国ATS 538N-H波束轮廓和切片厚度模体产品简介：
ATS 538N-H波束轮廓和切片厚度模体有两个扫描平面。散射面向扫描面方向为45°，垂直于另一个扫描面。
光束剖面很容易显示在不同的深度，并包含了大量的信息有关的声音光束的配置，因为它传播通过组织模拟介质。光束剖面清晰地显示了远场中的近场、焦距、聚焦区、光束宽度、侧面和光栅瓣以及光束发散情况。此外，近场的振幅变化表现为亮度的不同程度和远场振幅的几乎均匀性。
538N-H模型提供了一种评估成像系统在不同深度时的薄片厚度的方法。层厚或高度分辨率是空间分辨率的第三部分，显示结构在光束主轴前后产生的反射。切片厚度的变化与轴向和横向分辨率的变化是一致的。切片厚度越薄，分辨率越好;随着切片厚度的增加，空间分辨率降低。终身保修。

The phantom contains a thin plane of echogenic material embedded in a non-echoic rubber-based tissue-mimicking matrix. Model 538N-H has two scan planes. The scattering plane is oriented at 45° to one scan plane and perpendicular to the other.
The beam profile is easily displayed at varying depths, and contains a great deal of information regarding the configuration of the sound beam as it propagates through the tissue-mimicking media. The beam profile clearly displays the near field, focal length, focal zone, beam width, side and grating lobes and beam divergence in the far field. In addition, amplitude variations in the near field are displayed as varying degrees of brightness versus the almost homogeneity of the amplitude in the far field.
The Model 538N-H provides a means of evaluating the slice thickness of an imaging system at varying depths. Slice thickness or elevational resolution, the third component of spatial resolution, displays reflections produced by structures in front of or behind the beam’s main axis. The effect of changes in the slice thickness is identical to those seen with axial and lateral resolution. The thinner the slice thickness the better the resolution; as the slice thickness increases, the degree of spatial resolution decreases. Lifetime warranty.
