The E2 Pro is a portable Color Doppler that delivers an excellent balance of cost performance and quality. Designed with a streamlined system, it offers an easier work experience than other entry-level systems, while being equipped with comprehensive standard ultrasound functions and a wide range of probes for various applications. Its Wide-Scan feature enlarges ultrasound images during real-time scans using linear or convex probes, providing a more complete view of large lesions. The real-time panoramic imaging function extends the field of view, enhancing the measurement and diagnostic efficiency for large organs or long vessels. Additionally, the Vis-Needle feature improves needle visualization through ultrasound beam steering and deflection, reducing harm to surrounding tissue and increasing the success rate of needle punctures.
