RECOVERY FUNCTION OF PARAMETERS IN AN ULTRASOUND SYSTEM

1 . An ultrasound system, comprising:

an input unit for allowing a user to input instructions, the instructions including a setting instruction for setting values of a plurality of parameters and a recovery instruction for recovering the parameter values to previously set parameter values;

an ultrasound diagnostic unit for forming an ultrasound image of a target object based on the set parameter values;

a storage unit for sequentially and accumulatively storing the parameter values; and

a control unit responsive to the recovery instruction and being configured to retrieve the parameter values from the storage unit and recover the set parameter values to previous parameter values based on the retrieved parameter values, wherein the ultrasound diagnostic unit is further configured to form an ultrasound image based on the recovered parameter values.

2 . The ultrasound system of claim 1 , further comprising:

a history information forming unit for forming history information representing parameters corresponding to the parameter values stored in the storage unit in a storing order of the parameter values; and

a display unit for displaying the ultrasound image and the history information.

3 . The ultrasound system of claim 2 , wherein the instructions further include a request instruction for displaying the history information on the display unit, and wherein the recovery instruction is for selecting one of the parameters on the history information.

4 . The ultrasound system of claim 3 , wherein the parameters include image parameters to optimize the ultrasound image and measurement parameters to measure a size of the target object.

5 . The ultrasound system of claim 3 , wherein the setting instruction includes a first instruction for setting values of the image parameters and a second setting instruction for setting values of the measurement parameters.

6 . A method of performing a recovery function in an ultrasound system, comprising:

a) allowing a user to input instructions, the instructions including a setting instruction for setting values of a plurality of parameters and a recovery instruction for recovering the set parameter values to previously set parameter values;

b) forming an ultrasound image of a target object based on the set parameter values;

c) sequentially and accumulatively storing the parameter values to a storage unit; and

d) in response to the recovery instruction, retrieving the parameter values from the storage unit and recovering the set parameter values to previous parameter values based on the retrieved parameter values.

7 . The method of claim 6 , further comprising:

forming history information representing parameters corresponding to the parameter values stored in the storage unit in a storing order of the parameter values; and

displaying the ultrasound image and the history information.

8 . The method of claim 7 , wherein the instructions further include a request instruction for displaying the history information on the display unit, and wherein the recovery instruction is for selecting one of the parameters on the history information.

9 . The method of claim 8 , wherein the parameters include image parameters to optimize the ultrasound image and measurement parameters to measure a size of the target object.

10 . The method of claim 8 , wherein the setting instruction includes a first instruction for setting values of the image parameters and a second setting instruction for setting values of the measurement parameters.
