Title:
ULTRASONIC IMAGING SYSTEM, METHOD, AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/191863
Kind Code:
A1
Abstract:
An ultrasonic imaging system (1), method, and apparatus. The system comprises: a transcranial focused ultrasound transducer (11) consisting of a high-frequency ultrasonic transducer (111) and a low-frequency ultrasonic transducer (112) and an ultrasonic excitation receiving device (12) connected to the transcranial focused ultrasound transducer (11). When a request of performing ultrasonic treatment on encranial tissue to be treated of a patient, the high-frequency ultrasonic transducer (111) is first controlled to measure the thickness of the cranium of the patient and the speed of an ultrasonic wave propagated in the cranium of the patient; then the measured thickness of the cranium and the speed are fed back to the low-frequency ultrasonic transducer (112), and focusing parameter compensation is performed on ultrasonic transmit signals and ultrasonic receive signals of the low-frequency ultrasonic transducer (112); finally, the low-frequency ultrasonic transducer (112) focuses the encranial tissue to be treated according to a compensated ultrasonic transmit signal sequence and performs sound field compensation for an encranial image according to a compensated ultrasonic receive signal sequence, thereby improving the accuracy of ultrasonic transcranial focusing and the definition of ultrasonic imaging.
