An ultrasound diagnosis apparatus includes: a two-dimensional (2D) transducer array in which a plurality of transducers that transmit/receive an ultrasound signal to/from an object are arranged in two dimensions; an analog beamformer configured to perform analog beamforming in a first direction, and perform analog beamforming in a second direction perpendicular to the first direction on signals respectively received by the plurality of transducers; and a digital beamformer configured to perform digital beamforming on the signals that are analog-beamformed in the first direction, and perform digital beamforming on the signals that are analog-beamformed in the second direction.

An ultrasound diagnostic apparatus includes an ultrasound probe including a housing in which a first transducer array is disposed at one end and a second transducer array is disposed at the other end, a sensor that is provided in the housing and outputs information for acquiring motion information of the ultrasound probe or angle information of the ultrasound probe, and a processor that acquires used array information indicating which of the first transducer array and the second transducer array is used. The processor is configured to acquire the motion information or the angle information based on the output of the sensor and determine a motion or a position of the ultrasound probe with respect to a subject based on the acquired motion information or angle information and the used array information.

A method of quantifying a 3D fractional moving blood volume (3D-FMBV) in a tissue volume of a subject using an ultrasound system, including acquiring images of the tissue volume from a power doppler scan of the tissue volume; applying image enhancement settings to the images; segmenting an organ, tissue or region thereof from the image data; determining geometric partitions of the segments based on distance from the transducer head of the ultrasound system; and computing a 3D-FMBV using a 3D-FMBV analysis algorithm from the partitions.
