Abstract
The purpose of this paper is to discuss the optimization and improvement of medical ultrasound imaging system to meet the needs of high quality and high efficiency imaging technology in modern medical field. Firstly, this paper reviews the basic principle of ultrasonic imaging and the basic composition of medical ultrasonic imaging system, as well as the technical characteristics of the current system. Then, the main challenges of the current system, such as image quality, resolution and penetration depth, real-time and dynamic imaging, operation convenience and user friendliness, are analyzed in depth. To overcome these challenges, this paper proposes a series of optimization strategies. In the design and improvement of ultrasonic probe, the accuracy and efficiency of imaging are improved by optimizing probe material, shape and size, and developing multi-frequency and multi-array probe. In terms of signal processing and imaging algorithm optimization, this paper proposes the application of digital signal processing technology, the development of high-resolution imaging algorithm, and the combination of elastic imaging technology and blood flow imaging technology to improve image quality and real-time performance.
