Technology Corp., Ltd Palm B Mode Ultrasound System [Model: AV-2000 & AV-2010] APPLICATION RANGE This device is suitable in hospitals and clinics for diagnosing liver, GB, spleen, kidney, pancreas, heart, bladder, and uterus, as well as in pet hospitals for veterinary use. Its low energy consumption makes this device particularly suitable for bedside, ambulatory and emergency conditions, such as first aid and fieldwork. FEATURE SET This device uses microcomputer technology, Digital Scanning Converter (DSC), variable aperture, multi-section dynamic focusing, high dynamic low noise and wide band preamplifier, log compression, TGC control, dynamic filtering, edge enhancement and frame correlation. Embedded components allow a clear, stable and high-resolution image. • Display modes: B, B+B, B+M, M; Gray scales: 256 levels. • Real time scanning or picture freezing for analysis • Soft-touching keyboard and track ball to make operation faster, convenient and flexible. • Portable structured with plastic cover, 5 inch LCD, outside power supply, flock of Filed Programmable Gate Arrays (FPGA) and Surface Mounting Technology (SMT). The use of integrated circuits makes this device one of the smallest and lightest of its kind in the world. •This device has passed clinical verifications of safety and diagnosis validity.
