Ultrasonic diagnostic apparatus and method for acquiring a measurement value of a ROI

1. A method of operating an ultrasonic diagnostic apparatus, the method comprising:

displaying an ultrasonic image in a first region of a display unit;

selecting a region of interest (ROI) in the ultrasonic image;

displaying a first scan conversion image and a second scan conversion image in a second region, wherein the first scan conversion image is generated by enlarging or reducing an image corresponding to the selected ROI at a first magnification and the second scan conversion image is generated by enlarging or reducing the image corresponding to the selected ROI at a second magnification; and

acquiring a first measurement value of the ROI on the basis of the first scan conversion image, acquiring a second measurement value of the ROI on the basis of the second scan conversion image, and acquiring a third value calculated on the basis of the first and second measurement values,

wherein resolution of the scan conversion image is equal to or higher than resolution of the ultrasonic image.

2. The method of claim 1 , wherein the selecting of an ROI comprises selecting the ROI on the basis of a user input,

wherein the user input comprises at least one of an input for selecting a certain region in the ultrasonic image, an input of a coordinate value of the certain region, and an input for selecting a specific object included in the ultrasonic image.

3. The method of claim 1 , wherein the acquiring of the first measurement value and the second measurement value comprises acquiring at least one measurement value of a distance, an area, an angle, and a volume of an object of interest included in the ROI.

4. The method of claim 1 , further comprising displaying the first measurement value and the second measurement value.

5. The method of claim 1 , wherein,

the displaying of the first scan conversion image and the second scan conversion image comprises displaying the first scan conversion image with the first magnification and displaying the second scan conversion image with the second magnification.

6. The method of claim 1 , wherein the displaying of the first scan conversion image and the second scan conversion image comprises:

detecting an edge of an object of interest included in the ROI on the basis of image data corresponding to the ROI; and

displaying the detected edge of the object of interest on at least one of the first scan conversion image and the second scan conversion image.

7. The method of claim 6 , wherein the detecting of an edge comprises detecting the edge of the object of interest on a basis of first and second edge detection techniques.

8. The method of claim 7 , wherein the displaying of the first scan conversion image and the second scan conversion image comprises displaying a first edge detection image, in which a first edge detected by the first edge detection technique is displayed on at least one of the first scan conversion image and the second scan conversion image, and a second edge detection image in which a second edge detected by the second edge detection technique is displayed on at least one of the first scan conversion image and the second scan conversion image.

9. An ultrasonic diagnostic apparatus comprising:

a user input interface that receives a user input for selecting a region of interest (ROI) in an ultrasonic image;

an image processor that generates a first scan conversion image by enlarging or reducing an image corresponding to the ROI at a first magnification and generates a second scan conversion image by enlarging or reducing the image corresponding to the ROI at a second magnification;

a display that displays the first scan conversion image and the second scan conversion image; and

a controller that acquires a first measurement value of an object of interest in the ROI on the basis of the first scan conversion image, acquires a second measurement value of the object of interest in the ROI on the basis of the second scan conversion image, and acquires a third value calculated on the basis of the first and second measurement values;

wherein a resolution of the scan-converted image is equal to or higher than a resolution of the ultrasonic image.

10. The ultrasonic diagnostic apparatus of claim 9 , wherein the user input interface receives at least one of an input for selecting a certain region in the ultrasonic image, an input of a coordinate value of the certain region, and an input for selecting a specific object included in the ultrasonic image.

11. The ultrasonic diagnostic apparatus of claim 9 , wherein the controller acquires at least one measurement value of a distance, an area, an angle, and a volume of the object of interest included in the ROI.

12. The ultrasonic diagnostic apparatus of claim 9 , wherein the display unit displays the first measurement value and the second measurement value.

13. The ultrasonic diagnostic apparatus of claim 9 , wherein,

the display unit displays the first scan conversion image with the first magnification and the second scan conversion image with the second magnification.

14. The ultrasonic diagnostic apparatus of claim 9 , further comprising an edge detector that detects an edge of the object of interest included in the ROI on the basis of image data corresponding to the ROI,

wherein at least one of the first scan conversion image and the second scan conversion image includes the detected edge.

15. The ultrasonic diagnostic apparatus of claim 14 , wherein the edge detector detects the edge of the object of interest on a basis of first and second edge detection techniques.

16. The ultrasonic diagnostic apparatus of claim 15 , wherein the display displays a first edge detection image, in which a first edge detected by the first edge detection technique is displayed on at least one of the first scan conversion image and the second scan conversion image, and a second edge detection image in which a second edge detected by the second edge detection technique is displayed on at least one of the first scan conversion image and the second scan conversion image.

17. The method of claim 1 , wherein the third value includes at least one of an average value, variance, and standard deviation of the first measurement value and second measurement value.
