提高生物组织磁声电特性成像质量的方法研究
Research on methods to improve the magnetoacoustic imaging quality of electrical characteristics of biological tissue
摘要
Abstract
The functional changes of biological tissues occur earlier than structural lesions.Magnetic acoustic imaging can not only provide functional imaging but also achieve high spatial resolution,so magnetoacoustoelectric imaging is helpful for the early diagnosis of diseases such as cancer.However,the magnetic acoustic signal is weak,the signal-to-noise ratio is affected by signal attenuation,ultrasonic interference,and electromagnetic interference.To improve the image quality of magnetic,acoustic,and electrical character-istics,researchers have proposed a series of methods.This paper summarizes the research progress in enhancing the quality of magneto-acoustic-electric imaging in recent years,analyzes the advantages and disadvantages of enhancing the strength of detection signal,the quality of acquisition signal and the efficiency of signal reconstruction by improving the electromagnetic excitation,detection accuracy and signal-to-noise ratio,and looks forward its development prospects.关键词
