And the results demonstrated that the resolution was clearly improved and contrast ratio gains of 9. As shown in the figure, amplitude scaling, phase shifting of each antenna elements and their sum have been carried out digitally. Samsung’s innovative hybrid beamformer technology is comprised of both advanced hardware and software, allowing for intricate digital programming, which better defines the shape of the ultrasound pulse. Sun-D2 is an ergonomically designed portable and ease-of-use pocket ultrasound system for multi-specialty uses, such as adults, pregnant women, pediatric patients and neonates. HV7351 is ideal for demanding space-constrained applications such as portable medical ultrasound systems and wireless ultrasound probe systems. We offer 1 through 5 year service package options. It is very important that the full ultrasound system be optimized to accommodate the increased SNR capabilities of new devices, including the digital beamformer (digital delay and summation), digital filters, detectors, and compression mapping. The chip retrieved successfully two B-mode phantom images with a steering angle from -45 (°) to +45 (°), the maximum delay range of 8 μs, and the delay resolution of 6. nSIGHT Imaging incorporates the use of a precision beamformer along with powerful massive parallel processing. The CX50 combines the broadband capabilities of a digital beamformer with the broadband signals produced by PureWave transducers.
