ATS 551微小解剖特征模体

ATS 551超声模体提供了一种评估高频（约 7.5-20 MHz）超声系统性能的综合方法，该系统旨在检测微小的解剖特征。

我们的小零件模体设计结合了单丝线目标和不同尺寸和对比度的模仿圆柱形目标的组织。 单丝线目标的直径为0.05 毫米，以优化 7.5 MHz 或更高频率下的显示图像。 提供四组线目标来评估垂直和水平校准测量、死区和轴向横向分辨率。

Detect Small Anatomical Features The CIRS Model ATS 551 provides a comprehensive means of evaluating the performance of higher frequency (approximately 7.5- 20 MHz) ultrasound systems designed to detect small anatomic features.

 Our Small Parts Phantom is designed with a combination of monofilament line targets and tissue mimicking cylindrical targets of varying sizes and contrasts. The monofilament line targets have a diameter of 0.05 mm, to optimize the displayed image at frequencies of 7.5 MHz or greater. Four groups of line targets are provided to evaluate the vertical and horizontal calibration measurements, dead zone and axial-lateral resolution. 

The CIRS Model ATS 551 provides enhanced axial-lateral resolution targets (down to 0.25mm spacing) over the standard axial-lateral targets.
