Ultrasound System and Method, and Ultrasound Probe

摘要

An objective of the present invention is to provide an ultrasound system which can correct a positive-negative asymmetry in pulse inversion (PI) and obtain a high-image quality ultrasound image. To carryout an asymmetry correction of a transmission assembly circuit comprising an oscillation adjustment amplifier (10) and an ultrasound oscillator array (90), correction data obtained in a calibration mode is stored in a correction memory (46), and positive-negative asymmetry of an overall receiving assembly circuit comprising a computation unit (45) is corrected in a diagnostic mode of the device using the correction data.

主权项

1. An ultrasound system comprising:
a transmission unit which transmits a first transmission signal and a second transmission signal obtained by polarity inversion of the first transmission signal; an ultrasound probe which transmits an ultrasound based on the first transmission signal and the second transmission signal from the transmission unit, and receives an ultrasound as a reflection ultrasound; a reception unit which receives a first reception signal and a second reception signal corresponding to the first transmission signal and the second transmission signal based on the reflection ultrasound received by the ultrasound probe; and a storage unit which stores correction data for correcting a positive-negative asymmetry based on an addition result of the first reception signal and the second reception signal in a calibration mode, wherein the reception unit executes a correction computation using the addition result of the first reception signal and the second reception signal, and the correction data stored in the storage unit in a diagnostic mode.
