Abstract
An ultrasound imaging apparatus for providing a volumetric ultrasound image of an image volume, wherein the ultrasound imaging apparatus comprises: a row-column addressed transducer array configured to convert excitation electrical pulses into an ultrasound pressure field and to convert received ultrasound echo pressure fields into echo signals; a beamformer module configured to beamform the echo signals using dynamic receive focusing to produce respective image values at a first set of image points within the image volume; a reconstruction module configured to: determine a set of trajectories, each trajectory intersecting an image point of the first set of image points, map a second set of image points of the image volume onto the first set of image points, and to compute respective image values at the mapped image points of the second set of image points from the image values of the image points of the first set of image points.
