S218 is a full-digital black and white ultrasoound diagnostic instrument with high cost performance and high stability. This model supports convex array,tras-vaginal, high-frequency linear array, micro-convex, rectcal and other probes, and it is rich in obstetric and conventional measurement software.The model features a more stable LED display based on the original XF218, adding 16 kinds pseudo-color display modes and support video printers and external VGA displays and USB ports.
