Sub-performing transducer element detection for medical ultrasound |
| 摘要 |
Sub-performing elements of an ultrasound transducer array are detected. The power, such as current, used by or provided to the transmit driver is measured. By driving each element or group of elements separately, defective elements or groups of elements are detected from the amount of power used. |

1. An ultrasound system comprising:
an array of ultrasound transducer elements; a transmit driver connectable or connected with the ultrasound transducer elements of the array; a power source connected with the transmit driver; a current sensor positioned to sense current from the power source provided to the transmit driver; and a processor configured to detect a defective element of the ultrasound transducer elements based on the current. |
