声辐射力磁共振成像
摘要：
本发明提供了一种医学仪器(200、400)，包括磁共振成像系统(202)和高强度聚焦超声系统(222)。处理器(246)控制所述医学仪器。指令使所述处理器控制(100)所述磁共振成像系统以使用脉冲序列(254)来采集磁共振数据。所述脉冲序列包括声辐射力成像脉冲序列(500、600)。所述声辐射力成像脉冲序列包括激励脉冲(512)，以及应用在射频激励脉冲期间以选择性激励感兴趣区域(239)的多维梯度脉冲(514)，所述感兴趣区域涵盖波束轴的至少部分和目标区。所述指令使所述处理器控制(102)所述高强度聚焦超声系统以在所述声辐射力成像脉冲序列期间对所述目标区进行超声处理，并且使用所述磁共振数据来重建(104)辐射力图像(258)。
摘要（英）：

The invention provides for medical instrument (200, 400) comprising a magnetic resonance imaging system (202) and a high intensity focused ultrasound system (222). A processor (246) controls the medical instrument. Instructions cause the processor to control (100) the magnetic resonance imaging system to acquire the magnetic resonance data using a pulse sequence (254). The pulse sequence comprises an acoustic radiation force imaging pulse sequence (500, 600). The acoustic radiation force imaging pulse sequence comprises an excitation pulse (512) and a multi-dimensional gradient pulse (514) applied during the radio frequency excitation pulse for selectively exciting a region of interest (239) encompassing a target zone and at least a portion of the beam axis. The instructions cause the processor to control (102) the high intensity focused ultrasound system to sonicate the target zone during the acoustic radiation force imaging pulse sequence and reconstruct (104) a radiation force image (258) using the magnetic resonance data.
