A procedure has been devised for monitoring many critical performance characteristics of clinical ultrasound systems. It is easy to use in a clinical environment and is sufficiently precise to check system consistency or reproducibility. The procedure permits monitoring the system as a whole with enough specificity to locate malfunctioning components. The range response of the system with the beam normal to a planar reflector in distilled water at room temperature is obtained in a single Polaroid image for various control settings. System performance, excluding B mode velocity calibration, display linearity, and position registration, may be routinely monitored with a minimum of measurements. A feasibility test confirmed the method's precision, reproducibility (2%), and ease of performance.
已设计出一种用于监测临床超声系统诸多关键性能特征的程序。它易于在临床环境中使用，且精度足以检查系统的一致性或可重复性。该程序允许对整个系统进行监测，具有足够的特异性以定位故障组件。在室温下，对于各种控制设置，在一张宝丽来图像中即可获得系统在蒸馏水环境中、声束垂直于平面反射器时的距离响应。除了B模式速度校准、显示线性度和位置配准之外，系统性能可通过最少的测量进行常规监测。一项可行性测试证实了该方法的精度、可重复性（2%）以及操作简便性。
