Ultrasonic probe, ultrasonic imaging apparatus and ultrasonic imaging method |
摘要 |
An ultrasonic probe is disclosed for reducing the influence of electromagnetic wave leakage to a magnetic resonance imaging (MRI) device even when the probe is inside the MRI gantry. The ultrasonic probe includes a piezoelectric material, an acoustic matching layer provided on the ultrasonic radiation side of the piezoelectric material, and backing material provided on a rear side of the piezoelectric material. A transmit beam former is used to control a transmit focal point of ultrasonic waves inside the body of a subject. A receive beam former controls a receive beam focal point of electronic waves inside the body of the subject. The ultrasonic imaging apparatus also includes a switch capable of electrically disconnecting the ultrasonic probe from a transmit/receive switch.
