Frequency: the center frequency of the ultrasound emitted by the probe, in megahertz (MHz). The higher the frequency the better the image resolution, the worse the penetration.
Bandwidth: The bandwidth of the echo signal that the probe can receive. The wider the bandwidth, the more signals it can receive and the more diagnostic information it can provide to the physician.
Sweeping field of view: convex array and phased array probe scanning fan-shaped image angle is called the scanning field of view. The size of the scanning field of view can be adjusted: the larger the scanning field of view, the larger the scope of observation, the more information, the slower the frame rate.
