2D Hip Joint

This is a basic measurement that is available in all diagnosis modes. You can measure the angle of two

straight lines to a straight line in a 2D image. This measurement is commonly used in the obstetrics appli-

cation.

1. Press the Softmenu button [4] 2D Hip Joint. “2D Hip Joint” is displayed on the left side of the screen.

2. Use the trackball and the Set button on the control panel to specify the rst straight line.

▶

Place the cursor at a desired position with the trackball, and press the Set button.

3. Repeat the above process to specify two other straight lines.

4. The angle between them will be calculated automatically.

▶

α: The angle between the rst and second straight lines.

▶

β: The angle between the rst and third straight lines.

5. When the measurement is nished, its result is shown on the screen. The angles α and β, and the Hip

Joint Type are displayed on the screen.

Please refer to the table below for Hip Joint Type information:

M Distance

This is a basic measurement that is available in M Mode only. You can specify two points in an M image

and measure the distance, elapsed time and velocity between them.

1. Press the Softmenu button [1] Distance to select M Distance. “M Distance” is displayed on the left side

of the screen.

2. Specify two points and measure the straight distance between them. The method for measuring a

line is the same as in “2D Distance (Line).”

3. When the measurement is nished, its result is shown on the screen.
