阅读说明：本技术 一种超声成像装置和方法、超声弹性检测装置和方法 (Ultrasonic imaging device and method, and ultrasonic elasticity detection device and method ) 是由 李双双 于 2018-08-24 设计创作，主要内容包括：一种剪切波产生方法及装置,包括：阵元一次性向感兴趣区域发射脉冲超声波,脉冲超声波在声场内至少形成两个焦点,以至少两个焦点为剪切波源形成沿与脉冲超声波发射方向垂直的方向传播的剪切波带。本发明同时公开一种剪切波超声弹性检测方法极其装置,由于在同一次脉冲超声波发射中,脉冲超声波在声场内会聚成多个焦点,在多个焦点的联合作用下,形成沿与脉冲超声波发射方向垂直的方向传播的剪切波带,从而扩大剪切波在组织内的传播范围,使得检测超声波可对大范围的组织进行弹性检测。(A shear wave generation method and apparatus comprising: the array elements transmit pulse ultrasonic waves to an interested area at one time, the pulse ultrasonic waves form at least two focuses in a sound field, and the at least two focuses are used as shear wave sources to form shear wave bands which are transmitted along the direction vertical to the transmitting direction of the pulse ultrasonic waves. The invention also discloses a shear wave ultrasonic elasticity detection method and a device thereof, because the pulse ultrasonic waves are converged into a plurality of focuses in the sound field in the same pulse ultrasonic wave emission, and a shear wave band which is transmitted along the direction vertical to the pulse ultrasonic wave emission direction is formed under the combined action of the focuses, thereby expanding the transmission range of the shear wave in the tissue and leading the detection ultrasonic wave to carry out elasticity detection on the tissue in a large range.)
