摘要：
The present invention relates to determining the rotation of an interventional device in an ultrasound field. An interventional device is provided that is suitable for being tracked in an ultrasound beam of a beamforming ultrasound imaging system by correlating transmitted ultrasound signals from the beamforming ultrasound imaging system as detected by ultrasound receivers attached to the interventional device with the beamforming beam sequence of the ultrasound signals. The interventional device includes a longitudinal axis (A-A′), a first linear sensor array (12) comprising a plurality of ultrasound receivers (R1 . . . n) wherein each ultrasound receiver has a length (L) and a width (W), and wherein the array extends along the width (W) direction. Moreover the first linear sensor array (12) is wrapped circumferentially around the interventional device with respect to the axis (A-A′) such that the length (L) of each ultrasound receiver is arranged lengthwise with respect to the axis (A-A′).
