displacement or strain imaging
位移及应变成像 strain elastography(SE) and strain-rate imaging (SRI)
应变弹性图(SE)应变率成像(SRI) quasi static
准静态 mechanically induced –either active external displacement of tissue surface1 or passive internal physiologically induced2
机械运动诱发-组织表面的机械运动加压诱发(注1)或者体内生理运动诱发(注2) strain or strain rate
应变或应变率 qualitative, although tools often provided to analyse image characteristics
定性方法,虽然通常也可以提供针对图像特点分析的定量工具 full area image,refreshed at up to the ultrasound frame rate3
全域成像,依照超声成像帧频刷新(注3)

acoustic radiation force impulse (ARFI) imaging
脉冲声压触发成像(ARFI) dynamic
动态成像 ultrasound induced –focused radiation force impulse at depth
超声诱发-聚焦超声脉冲组织深部加压 displacement
位移 qualitative
定性 single image within a box
仅取样框内成像
shear-wave speed MEASUREMENT
剪切波速度测量 transient elastography (TE)4
瞬时弹性成像(TE)注4 mechanically induced –impulse (“thump”) at tissue surface
机械运动诱发-组织表面冲击(击打) shear-wave speed5
剪切波速度(注5) quantitative
定量 single measurement,beam-line average
仅仅测量数据-基线处平均数据
point shear-wave elastography (pSWE), also known as ARFI quantification4
点剪切波速度弹性成像(pSWE)-又名ARFI点定量 ultrasound induced –radiation force impulses focused at various depths
超声冲击诱发-在不同深度超声声波压力诱发 shear-wave speed5
剪切
