Abstract
An ultrasound imaging system (100) includes a transducer array (102). The transducer array includes a first set of transducer elements (206 or 208, 302 or 304) and a second set of transducer elements (208 or 206, 304 or 302). The first and second sets of transducer elements includes long axes and are angularly offset from each other by a non-zero angle with respect to the long axes. The ultrasound imaging system further includes a velocity processor (120) that processes echoes received by the first and second sets of transducer elements and determines an axial and two transverse flow velocity components based on the received echoes.
Claims27
An ultrasound imaging system, comprising:
- a transducer array, including a first set of transducer elements and a second set of transducer elements,
- wherein the first and second sets of transducer elements includes long axes and are angularly offset from each other by a non-zero angle with respect to the long axes;
- and
- a velocity processor that processes echoes received by the first and second sets of transducer elements and determines an axial and two transverse flow velocity components based on the received echoes.
A method, comprising:
- receiving first echoes in response to a first ultrasound beam traversing a first plane in a first direction;
- receiving second echoes in response to a second ultrasound beam traversing a second plane in a second direction, wherein the first and second direction are at an angle with respect to each other;
- and
- estimating three orthogonal flow velocity components based on the first and second echoes.
A computer readable storage medium encoded with computer readable instructions, which, when executed by a processer, cause the processor to:
- process data generated by a biplane transducer array utilized in a phased array mode and determine 3D orthogonal velocity components based on the data and with a 3D vector flow imaging processing algorithm.
