一种用于对在对象的对象体积中的空化进行成像的设备，包括多个换能器元件和控制装置。所述控制装置被配置成：控制所述换能器元件中的至少第一换能器元件以生成具有聚焦区域的超声；接收来自第一组换能器元件的无源检测信号，并根据无源检测信号生成聚焦区域中的空化的空化图像；控制换能器元件中的至少第二换能器元件以生成反射成像超声；接收来自第二组换能器元件的反射成像检测信号，并根据反射成像检测信号生成反射图像；将反射图像与对象体积的3D图像配准，以获得第一组换能器元件的坐标系与3D图像的坐标系之间的变换；并将变换应用于空化图像以使空化图像与3D图像对齐。 Apparatus for imaging cavitation in a subject volume of a subject comprises a plurality of transducer elements, and control means. The control means is arranged to: control at least a first one of the transducer elements to generate ultrasound having a focal region; receive passive detection signals from a first group of the transducer elements and generate from the passive detection signals a cavitation image of cavitation in the focal region; control at least a second one of the transducer elements to generate reflective imaging ultrasound; receive reflective imaging detection signals from a second group of the transducer elements and generate from the reflective imaging detection signals a reflective image; register the reflective image wit
