ULTRASOUND METHOD AND SYSTEM FOR EXTRACTING SIGNAL COMPONENTS RELATING TO SPATIAL LOCATIONS IN A TARGET REGION IN THE SPATIAL AND TEMPORAL FREQUENCY DOMAIN

Ultrasound method for extracting information from signal components relating to spatial locations in a target region such as for example image reconstruction in the spatial and temporal frequency domain comprises the steps of:Transmitting an unfocussed acoustic wave in a target region;extracting information of the scatterers in the target region from signal components relating to spatial locations of the target region by applying a backpropagation algorithm to the radiofrequency signals generated by transformation of the reflected acoustic waves and which radiofrequency signals has been transformed in the frequency-wavenumber domain and transformed back to the time spatial domain after backpropagation processing, the system provides the further step of optimizing the extracted information by applying corrections to the radio frequency received signals in the frequency-wavenumber domain.The invention relates also to an ultrasound system for carrying out the said method.
