【摘要】:血流信息檢測(cè)及其成像因其獨(dú)特的優(yōu)勢(shì),在臨床上得到廣泛應(yīng)用。但常規(guī)經(jīng)顱多普勒超聲系統(tǒng)仍采用模擬和數(shù)字電路結(jié)合的傳統(tǒng)技術(shù),這類系統(tǒng)容易受到外界干擾且不能進(jìn)行多深度檢測(cè)。文章設(shè)計(jì)出一種全數(shù)字多普勒超聲血流檢測(cè)系統(tǒng)方案,彌補(bǔ)了傳統(tǒng)模擬系統(tǒng)存在的問題。多普勒仿體和人體實(shí)驗(yàn)結(jié)果表明,該系統(tǒng)能夠進(jìn)行多深度檢測(cè),確定血管的深度;同時(shí),還提高了檢測(cè)靈敏度、超聲穿透力和系統(tǒng)成像分辨率。
[Abstract]:Blood flow information detection and imaging are widely used in clinic because of their unique advantages. However, the conventional transcranial Doppler ultrasound system still uses the traditional technology of analog and digital circuits. This kind of system is vulnerable to external interference and can not carry out multi-depth detection. In this paper, a scheme of all-digital Doppler ultrasound blood flow detection system is designed, which makes up for the problems existing in the traditional analog system. The results of doppler simulation and human body experiments show that the system can be used for multi-depth detection to determine the depth of blood vessels, and at the same time, the detection sensitivity, ultrasonic penetration and imaging resolution of the system are improved.
