四维彩色超声

四维彩色超声摘要：近年来计算机技术革命化的进步被融入超声诊断系统，使得三维容积成像的速度在短短的几年时间里得到了极大提高，目前已经发展到能够进行动态的四维成像。在2002年研制成功了四维超声技术，第四维是指时间向量。4d超声波技术就是采用3d超声波图像加上时间维度参数，可以显示人体内脏器官或胎儿在母体内即时动态的活动图像。它的确为一些复杂声像结构的判断提供了大量辅助信息，并对某些病变的诊断起到二维超声无法替代的作用。它的应用潜能正随着经验的积累被逐步开发出来。关键词：四维彩色超声4dabstract：putertechnology,inrecentyearshavebeenintegratedintotherevolutionaryadvancesinurasounddiagnosissystem,makinhreedimensionalvolumeimagingspeedinashortperiodoftimeseveralyearshasbeengreatlyimproved,hasbeendevelopedtobeabletocarryoutthedynamicsoffourdimensionalimaging.in2002,thesuccessfuldevelopmentofafourdimensionalurasoundtechnologyisthefourthdimensionalvectortime.4durasoundtechnologyistheuseof3durasoundimagestoaddthedimensionoftimeparameters,youcanshowthatthehumanbodyorgansorthefetusinitsmothersbodytheactivitiesofreaimedynamicimage.itistrueforanumberofpleaudiovisualstructuresofthejudgetoprovidealargenumberofauiliaryinformation,andthediagnosisofcertaindiseasesplayatwodimensionalurasoundcannotbereplaced.itspotentialapplicationiswiththeaccumulationofeperiencehasbeengraduallydeveloped.keywords:
