Rotating Images

You can rotate images left or right in 90-degree increments, or freely rotate images at any angle. Freely rotating images can be useful when you are reading diagonally acquired CR images of a tibia or fibula and want the bone to go straight up and down in the viewport.

Rotation settings are applied to all images in the series.

Arbitrary rotation angles used in key images and presentation states will be rounded to the nearest 90-degree angle when viewed in earlier versions of InteleViewer or a third-party viewer.

To rotate an image in 90-degree increments:

1. Select the required image.

2. To rotate the image to the left or to the right, do one of the following:

   • From the main menu, choose Tools | Rotate Left 90 Degrees or Tools | Rotate Right 90 Degrees.
   • From the Free Rotate Tool menu in the toolbar, select Rotate Left 90 Degrees or Rotate Right 90 Degrees.

   The image changes orientation.

3. Repeat step 2 as many times as required to rotate the image in additional 90-degree increments.
4. To revert the image to its original orientation, choose Tools | Reset (Ctrl+Backspace).

To rotate an image freely:

1. Select the required image.

2. From the main menu, choose Tools | Free Rotate, or click the Free Rotate tool , and then click and drag your mouse to the left or to the right to freely rotate the image to the desired angle.

   The cursor changes to indicate that you are freely rotating.

   The image rotates around the middle point of the viewport.

3. To revert the image to its original orientation, choose Tools | Reset (Ctrl+Backspace).
