Ultrasound imaging with beamforming from data that are enhanced by a neural network in the signal domain

[0001] To obtain a data-structure that is characteristic of a physical object, a computer receives (413) sensor-data ({{y}}|↓) from a sensor-array. the received sensor-data ({{y}}|↓) is - in spatial and temporal data arrangement - a sub-set of sensor-data of a reference sensor-array. the computer uses a neural network to enhance (433) the received sensor-data to enhanced sensor-data so that - in spatial and temporal data arrangement - the enhanced sensor-data correspond to the sensor-data of the reference sensor-array. an imaging module beamforms (453) the enhanced sensor-data to the data-structure. the neural network has been trained (402) to obtain network weights, with sensor-data from the ultrasound transducer elements of the reference sensor-array.
