ULTRASOUND MEASUREMENT ASSEMBLY FOR MULTIDIRECTIONAL MEASUREMENT

摘要

The present invention relates to an ultrasound measurement assembly (10) and an according method for performing an ultrasound measurement. It is intended to drive an ultrasound transmitter element (18) for transmitting ultrasound waves, with a driving signal having a plurality of different driving frequencies simultaneously. Herein a driving unit (12) is generating at least one driving signal (20) for at least one corresponding ultrasound transmitter element (18): As an effect each ultrasound transmitter element (18) will generate a multidirectional ultrasound wave. Additionally it is intended to design a driving signal 20 in a way, that an overall ultrasound beam comprises individual frequency spectra in different spatial directions (22). If a part of overall ultrasound beam is reflected, a sensing signal (30) is generated by a sensing unit (28). The sensing signal (30) is comprised an individual frequency spectrum. The sensing signal is received by a processing unit which determines the frequency spectrum and therefore can determine to which spatial direction (22) or spatial region the signal was sent.
