Abstract

An ultrasonic apparatus including a plurality of channels, each includes a transmission channel configured to generate and output a transmission signal based on a synchronization signal; a transducer element configured to convert the transmission signal output from the transmission channel into an ultrasonic signal and output the ultrasonic signal; a transceiver switching circuit configured to attenuate and output the transmission signal output from the transmission channel, and to output a reception signal that returns after the ultrasonic signal is transmitted to an object and is reflected from the object; and a reception channel configured to receive the attenuated output transmission signal and the output reception signal, and to detect transmission waveform information based on the attenuated transmission signal. The ultrasonic apparatus may further include a controller configured to store reference waveform information according to a transmission condition, and to compare the detected transmission waveform information with the reference waveform information.

First claim

What is claimed is:

1. An ultrasonic apparatus including a plurality of channels, each comprising:
a transmission channel configured to generate and output a transmission signal based on a synchronization signal;
a transducer element configured to convert the transmission signal output from the transmission channel into an ultrasonic signal and output the ultrasonic signal;
a transceiver switching circuit configured to attenuate and output the transmission signal output from the transmission channel, and to output a reception signal that returns after the ultrasonic signal is transmitted to an object and is reflected from the object; and
a reception channel configured to receive the attenuated output transmission signal and the output reception signal, and to detect transmission waveform information based on the attenuated transmission signal,
wherein the ultrasonic apparatus further comprising:
a controller configured to store reference waveform information according to a transmission condition, and to compare the detected transmission waveform information with the reference waveform information.

2. The ultrasonic apparatus according to claim 1 , wherein, when the detected transmission waveform information is different from the reference waveform information, the controller is configured to stop an operation of the transmission channel.

3. The ultrasonic apparatus according to claim 2 , wherein the plurality of channels comprises a first channel and a second channel including a transducer element adjacent to a transducer element of the first channel, and
wherein the controller is configured to:
when the transmission waveform information detected in the first channel is different from the reference waveform information, stop the operation of the transmission channel of the first channel; and
control the reception channel of the first channel such that a reception channel of the first channel obtains an ultrasonic image data based on a reception signal received by a reception channel of the second channel.

4. The ultrasonic apparatus according to claim 2 , further comprising:
a display,
wherein, when the detected transmission waveform information is different from the reference waveform information, the controller is configured to display that there is an error in the transmission channel through the display.

5. A method of controlling an ultrasonic apparatus including a plurality of channels, the method comprising:
generating and outputting, by a transmission channel, a transmission signal based on a synchronization signal;
converting, by a transducer element, the transmission signal into an ultrasonic signal, and outputting, by a transceiver switching circuit, a reception signal that returns after the ultrasonic signal is transmitted to an object and is reflected from the object;
attenuating and outputting, by the transceiver switching circuit, the transmission signal;
receiving, by a reception channel, the attenuated output transmission signal and the output reception signal, and detecting transmission waveform information based on the attenuated transmission signal; and
comparing, by a controller, the detected transmission waveform information with reference waveform information.

6. The method according to claim 5 , further comprising:
when the detected transmission waveform information is different from the reference waveform information, stopping, by the controller, an operation of the transmission channel.

7. The method according to claim 6 , wherein the plurality of channels comprises a first channel and a second channel including a transducer element adjacent to a transducer element of the first channel, and
the method further comprising:
when the transmission waveform information detected in the first channel is different from the reference waveform information, stopping, by the controller, the operation of the transmission channel of the first channel; and
controlling, by the controller, the reception channel of the first channel such that a reception channel of the first channel detects an ultrasonic image based on a reception signal received by a reception channel of the second channel.

8. The method according to claim 6 , further comprising:
when the detected transmission waveform information is different from the reference waveform information, displaying, by the controller, that there is an error in the transmission channel.
