SYSTEM AND METHOD FOR ESTIMATING LOCATION OF TIP OF INTERVENTION DEVICE IN ACOUSTIC IMAGING

An acoustic imaging apparatus and method receive a sensor signal from a passive sensor disposed on a surface of an intervention device which is disposed in an area of interest, wherein the passive sensor is located at a fixed distance from the tip of the intervention device. A processor is configured to ascertain an estimated range of locations of the tip of the intervention device in an image plane by using the sensor signal and an estimated effective distance, projected onto the image plane, from the passive sensor to the tip of the intervention device. 声学成像装置和方法从被设置在介入设备的表面上的无源传感器接收传感器信号，所述介入设备被设置在感兴趣区中，其中，所述无源传感器位于距所述介入设备的尖端固定距离处。处理器被配置为通过使用所述传感器信号以及从所述无源传感器到所述介入设备的所述尖端的被投影到图像平面上的估计有效距离来确定所述介入设备的所述尖端在所述图像平面中的估计位置范围。
