Abstract

The invention provides an ultrasound imaging system, comprising an array of transducer elements grouped into element groups, wherein the element groups comprise a plurality of first element groups (having a first orientation) and a plurality of second element groups (having a second orientation different from the first orientation). A first conductor is connected to each of the elements in each first element grouping and a second conductor is connected to each of the elements in each second element grouping. Each element group is adapted to be activated for transmission or reception by the application of a bias voltage, by way of a plurality of bias voltage circuits, and controlled by a plurality of transmit and receive circuits. The system is adapted to acquire first ultrasound data, wherein the bias voltage is applied to the first conductors of the array (or a sub-array) and the transducers receive a signal from a transmit and receive circuit. The system is further adapted to acquiresecond ultrasound data, wherein the bias voltage is applied to the second conductors of the array (or a different sub-array) and the transducers receive a signal from a transmit and receive circuit.Thus, the ultrasound system is adapted to acquire two separate ultrasound data (such as ultrasound images) corresponding to different views without requiring any physical movement of the array.

Description

technical field [0001] The present invention relates to ultrasound imaging systems that use arrays of transducer elements, in particular capacitive micromachined ultrasound transducer (CMUT) elements. Background technique [0002] figure 1 A typical imaging workflow 1 is shown, in this example for performing vascular imaging, employing an ultrasound patch 2 (in this example a low-profile ultrasound probe) during a procedure that requires visual guidance to aid in needle insertion. For optimal image navigation support it is important to have multiple views of the region of interest 3 . In some cases, a single 2D view may not provide sufficient visual guidance, and it may be desirable to have both cross-sectional and longitudinal views of the region of interest. [0003] There are several ways to capture both views using a regular 2D sensor: however, this requires manually moving the sensor by 90 degrees, which may result in losing the reference start position of the initial...
