In order to address the limitations of traditional handheld ultrasound scanning systems, such as narrow field of view, and nonstandardization, this article presents the design and implementation of comprehensive ultrasound imaging system based on a ring array. This system encompasses a 512-element ultrasonic annular array, a high-performance 256 / 1 024-channel acquisition circuit, an efficient PCIe-based data transmission module, and comprehensive software for acquisition control and rapid imaging. The multi-channel acquisition circuit comprising eight 32 / 128 ultrasonic transceiver control modules enables full-matrix data acquisition and high-speed transmission of 512 annular array elements within 12 seconds, achieving a remarkable data transmission efficiency of 1. 2 Gb / s. The system boasts a broadband frequency range of 0. 16~ 15 MHz and adjustable A/ D sampling rates ranging from 12. 5 ~ 100 MHz, which meets the diverse requirements of clinical and experimental applications. The acquisition control software facilitates multi-mode ultrasound data acquisition, enabling the rapid imaging monitoring and secure storage of full-matrix data for subsequent precise image reconstruction. Phantom and in-vivo experiments show that the system can obtain an imaging range exceeding 10 cm×10 cm, resolve 1 mm abnormalities accurately, and provide detailed visualization of interfaces within biological tissues such as fat, muscle, and bone. These results demonstrate the system′s capability of performing circumferential scanning, producing comprehensive and standardized medical ultrasound images with a wide field of view.
