Abstract
The present invention consists of a method for a fast acquisition of two dimensional images by the use of synthetic transmit and receive apertures formed in the schematics with cross transducers and can be used for the reconstruction of three dimensional images. The method of a fast two dimensional image acquisition preserves the flat beam generation and irradiation of the sector of an investigated part of a human body by a single transmit array. Simultaneously, a switching of transmit (or receive) arrays and irradiation of the same sector of a human body by different transmit arrays with a consequent fine shifting and summation of the received and digitized information in the region of interest provides an additional focusing of the transmit (or receive) beam along the coordinate parallel to the flat beam plane. The schematics of transducers for the realization of this method are described. The suggested method works with digital beamformer schematics, when echo signals from every individual element of the receive arrays are amplified, digitized and stored in memory.
