Abstract

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.
