Chapter 5 Measurements And Calculations

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

application.

1. Use the Softmenu switch [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.

X

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.

X

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

X

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:

Type α β

1a 60 ≤ α < 90 0 < β < 55

1b 60 ≤ α < 90 55 ≤ β < 90

2a/b 50 ≤ α < 60 0 < β < 90

2c 43 ≤ α < 50 77 ≤ β < 90

d 43 ≤ α < 50 0 < β < 77

3/4 0 < α < 43
