wherein the at least one ultrasound still cut is the original version of the ultrasound image.

3. The ultrasound diagnosis apparatus of claim 1 , wherein the one or more processors are further configured to determine the respective first time intervals based on a network delay time between the ultrasound diagnosis apparatus and the client apparatus.

4. The ultrasound diagnosis apparatus of claim 3 , wherein the one or more processors are further configured to determine the respective first time intervals when the at least one ultrasound still cut that corresponds to the time stamp and is obtained during a time between a current time point and a time point that is the network delay time before the current time point is stored in the memory.

5. The ultrasound diagnosis apparatus of claim 1 , wherein the one or more processors are further configured to transmit at least one ultrasound still cut including a time stamp corresponding to a time point closest to the first time stamp from among the stored at least one ultrasound still cut.

6. The ultrasound diagnosis apparatus of claim 1 , wherein the communicator is further configured to receive a first captured image acquired by the client apparatus at a time point corresponding to the first time stamp.

7. The ultrasound diagnosis apparatus of claim 6 , wherein the one or more processors are further configured to determine, based on a degree of similarity between each of the at least one ultrasound still cut corresponding to the first time stamp and the first captured image, at least one first output image with the degree of similarity that is greater than or equal to a predetermined threshold from among the at least one ultrasound still cut corresponding to the first time stamp and to transmit the at least one first output image to the client apparatus.

8. The ultrasound diagnosis apparatus of claim 6 , wherein the one or more processors are further configured to determine, based on a degree of similarity between each of the at least one ultrasound still cut corresponding to the first time stamp and the first captured image, at least one second output image with a highest degree of similarity from among the at least one ultrasound still cut corresponding to the first time stamp and to transmit the at least one second output image to the client apparatus.

9. The ultrasound diagnosis apparatus of claim 1 , further comprising an input interface further configured to receive a first input of stopping transmission of the ultrasound image to the client apparatus,

wherein the one or more processors are further configured to stop transmission of the ultrasound image to the client apparatus based on the first input and transmit only the time stamp to the client apparatus.

10. A method of controlling an ultrasound diagnosis apparatus, the method comprising:

acquiring ultrasound image data with respect to an object by transmitting ultrasound signals to the object;

obtaining an ultrasound image based on the ultrasound image data,

transmitting the ultrasound image and a time stamp indicating a time point when the ultrasound image is obtained in real-time to a client apparatus and storing, in a memory, at least one obtained ultrasound still cut by selecting the ultrasound image as the at least one obtained ultrasound still cut at respective first time intervals, together with the time stamp;

receiving a request for a still cut including a first time stamp from the client apparatus; and

transmitting to the client apparatus at least one ultrasound still cut corresponding to the first time stamp from among the stored at least one obtained ultrasound still cut.

11. The method of claim 10 , wherein the transmitting of the ultrasound image and the time stamp indicating the time point when the ultrasound image is obtained in real-time to the client apparatus comprises:

converting the ultrasound image into an ultrasound image with a lower resolution than an original version, to obtain a resulting ultrasound image; and

transmitting the resulting ultrasound image and the time stamp to the client apparatus, and

wherein the at least one ultrasound still cutis the original version of the ultrasound image.

12. The method of claim 10 , wherein the storing of the at least one obtained ultrasound still cut, in the memory at the respective first time intervals together with the time stamp comprises determining the respective first time intervals based on a network delay time between the ultrasound diagnosis apparatus and the client apparatus.

13. The method of claim 12 , wherein the determining of the respective first time intervals comprises determining the respective first time intervals when the at least one ultrasound still cut that corresponds to the time stamp and is obtained during a time between a current time point and a time point that is the network delay time before the current time point is stored in the memory.

14. The method of claim 10 , wherein the transmitting of the at least one ultrasound still cut corresponding to the first time stamp to the client apparatus comprises transmitting at least one ultrasound still cut including a time stamp corresponding to a time point closest to the first time stamp from among the stored at least one ultrasound still cut.

15. The method of claim 10 , wherein the receiving of the request for the still cut including the first time stamp from the client apparatus comprises receiving a first captured image acquired by the client apparatus at a time point corresponding to the first time stamp.

16. The method of claim 15 , wherein the transmitting of the at least one ultrasound still cut corresponding to the first time stamp to the client apparatus comprises:

determining, based on a degree of similarity between each of the at least one ultrasound still cut corresponding to the first time stamp and the first captured image, at least one first output image with the degree of similarity that is greater than or equal to a predetermined threshold from among the at least one ultrasound still cut corresponding to the first time stamp; and

transmitting the at least one first output image to the client apparatus.

17. The method of claim 15 , wherein the transmitting of the at least one ultrasound still cut corresponding to the first time stamp to the client apparatus comprises:

determining, based on a degree of similarity between each of the at least one ultrasound still cut corresponding to the first time stamp and the first captured image, at least one second output image with a highest degree of similarity from among the at least one ultrasound still cut corresponding to the first time stamp; and

transmitting the at least one second output image to the client apparatus.

18. The method of claim 10 , further comprising receiving a first input of stopping transmission of the ultrasound image to the client apparatus,

wherein the transmitting of the ultrasound image and the time stamp indicating the time point when the ultrasound image is obtained in real-time to the client apparatus comprises stopping transmission of the ultrasound image to the client apparatus based on the first input and transmitting only the time stamp to the client apparatus.

19. A computer program product comprising a non-transitory computer-readable recording medium having recorded thereon a program for performing the method of claim 10 on a computer.
