Problems solved by technology

[0011] Since the above repolarization method requires a lot of work and even requires reassembly of the ultrasound probe after repolarization, it is not used in practice
In addition, traditional ultrasound imaging equipment does not have any means to inform the estimated when depolarization will occur
Therefore, the operator must determine the replacement time based on the degradation of the image quality of the displayed image

[0041] Figure 5 is a first exemplary structural block diagram of the repolarization system according to the first embodiment of the present invention. Such as Figure 5 As shown, the repolarization system includes an ultrasonic probe repolarization device 50 and an ultrasonic probe 1 . The ultrasonic probe repolarization device 50 includes a connector 51 , a connection line 52 , a switch unit 53 , a high voltage power supply 54 , a controller 55 and an input unit 56 . The connector 51 is detachably connected to the connector 57 of the ultrasound probe 1 . The connector 57 is connected to the cable 26 . Other structures of the ultrasonic probe 1 are similar to those described above. Therefore, description of the ultrasonic probe 1 is omitted here.

[0042] The switching unit 53 includes a plurality of switching elements. The switching element is turned on / off by the controller 55 . At least a part of the switching element corresponds to the land 21 (23). Any switching ...

[0049] Figure 6 is a block diagram of the second exemplary structure of the repolarization system according to the second embodiment of the present invention. exist Figure 6 in, give with figure 1 , 2A Components with the same number as shown in 5 will work in a similar manner. Therefore, detailed descriptions of these components will be omitted here.

[0050] In the repolarization system according to the second embodiment, an ultrasound probe repolarization apparatus 60 includes a controller 61 instead of the controller 55 , an ultrasound probe identification table memory 62 , and an input unit 63 instead of the input unit 56 . The controller 61 controls the switching unit 53 and specifies which switching elements are to be turned on (or which lands are to be supplied with a predetermined high voltage). The controller 61 also controls the switching unit 53 to be turned on during the on period of the switching element. In addition, the controller 61 also controls the h...

[0058] When it is possible to classify the various types of ultrasonic probes 1 into a smaller number of groups according to the supply voltage required for repolarization, these classified voltage types can be input to the controller of the ultrasonic probe repolarization device to control the repolarization change. This classification is based on the fact that certain types of ultrasound probes can be repolarized with similar voltages. Applying control based on this supply voltage can simplify the operation of the operator and the control of the ultrasound probe repolarization device. A supply voltage corresponds to a predetermined voltage to be supplied for repolarization.

[0059] Figure 7 is a block diagram of a third exemplary structure of a repolarization system according to a third embodiment of the present invention. exist Figure 7 in, give with figure 1 , 2AComponents with the same number as shown in 5 will work in a similar manner. Therefore, detailed descr...

Abstract

A system for rapolarizing transducers in an ultrasonic probe (1) includes a plurality of transducers (2) and electrodes (5,7). The system includes a voltage generator (54) configured to generate a predetermined voltage high enough to repolarize the transducers, a switch (53) configured to control a supply of the predetermined voltage to the electrodes, a connector (51) configured to connect the electrodes to the switch through a plurality of lands (21,23), the lands being provided sufficiently insulated from each other to prevent a dielectric breakdown between the lands while repolarizing the transducers, an interface (56) configured to provide an instruction, and a controller (55) configured to control the voltage generator. An ultrasound imaging apparatus that uses the repolarization system and an ultrasonic probe are also provided.

Description

[0001] Cross References to Related Applications [0002] This application is based on, and claims priority from, prior Japanese Patent Application No. P2003-24554 filed on January 31, 2003, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a repolarization system for repolarizing a transducer used in an ultrasound probe for generating ultrasound waves. The invention also relates to an ultrasound probe and an ultrasound imaging device using the repolarization system. Background technique [0004] As is well known in the field of ultrasound imaging, an ultrasound probe used as part of an ultrasound imaging device includes a plurality of transducers. When high voltage is supplied to these transducers, they generate ultrasonic waves. The generated ultrasound waves penetrate the object or patient. The penetrated ultrasonic waves return from the object or patient as echo signals. The echo signals are converted ...
