Method of operating ultrasound image generating device with convertor array

The method involves transmitting a number of ultrasound transmission beams from each convertor array in a plane which cuts across a body of ultrasound scatter elements. Each transmission beam has a corresponding deflection angle and a corresponding focal or refractive point. The method also involves...

Zusammenfassung:	The method involves transmitting a number of ultrasound transmission beams from each convertor array in a plane which cuts across a body of ultrasound scatter elements. Each transmission beam has a corresponding deflection angle and a corresponding focal or refractive point. The method also involves obtaining, for each beam, a corresponding reception vector taken from the ultrasound, which is reflected by the scatter elements in a corresponding focal zone to the array. Each focal zone has a corresponding focal point. The method further involves representing the reception vectors in a sample or scan format to form an individual image. At least one of the following parameters changes during obtaining each beam of the individual image. The parameters are the F number, the transmission curve middle frequency, the receiver demodulation frequency, the beam width or the apodisation function. The beam angle and distribution of transmission beams change as a function of at least one of the changed parameters.
