加纳采购需求：黑白超声波、彩色多普勒超声波、心电图、数字X光、病人监护仪

I'm looking for a full digital handheld ultrasound machine specifically designed for livestock use, particularly for cattle, sheep, and goats. The device should be portable and user-friendly, enabling quick and accurate diagnostics on the field. I'm interested in features like image quality, battery life, and whether it can handle different breeds and conditions. Additionally, please provide details on the pricing, warranty options, and any available accessories or add-ons. It would be helpful to know the expected lead time for delivery and if there's technical support or training available after the purchase. Looking forward to your response with more information!
