Title: Ultrasonic probe
Inventor: NAKAMURA TAKAHIRO
IPC: A61B8/14
Filed: 1990-07-30
Abstract: PURPOSE:To prevent the generation of a crosstalk and to obtain the tomography image of a high analysis degree by constituting the probe so that a part of a driving pulse current supplied to a vibrator to be driven is not supplied to other vibrator. CONSTITUTION:A driving pulse current ia generated by a driver 9a passes through a signal line 11a and vibrates a vibrator 4a, and generates an acoustic pulse toward the inside of a body to be examined. In this case, since the signal line 11a has impedance Z, a potential difference is generated between the potential of a common connecting part 7 of the vibrator 4a side, and the potential of a common connecting point 13 of shield sides 12a-(f) of the signal lines 11a-(f), a partial current ic of the driving pulse current ia flows to other vibrators 4b, 4c,.... Therefore, the potential difference is detected by a current control means 8, and a current flowing through the common connecting point 7 is controlled so that this potential difference becomes zero. As a result, the potential of the common connecting point 7 becomes equal to the potential of the common connecting point 13, a current ie flowing through the shield side 12a of the signal line 11a becomes '0', and also, a current ic flowing to other vibrators 4b, 4c,... also becomes '0'.
