2D Localization
In acquisition mode (with the camera icon

These are used on images acquired using the Graduated Biopsy Compression Paddle (option) to
precisely locate a point of interest on the image, in order to introduce a neddle.
D Click on the (2D Localization) button to display the cross-hairs on the image.
D Move the mouse pointer onto the intersection of the cross-hairs, then press and
hold the left mouse button. The cursor changes to a pencil shape, and you can
move the cross–hairs by moving the mouse.
Move the cross-hairs exactly over the point of interest; you can now read their
position relative to the graduations of the compression paddle on the image.
D Click again on the (2D Localization) button to remove the cross-hairs.
Note:
When you close the exam, any 2D Localization cross-hairs on an image will be saved with the
image, and will be displayed again when the image is selected for review at a later stage.
On an image that has been saved on the database and is recalled in image review mode, the
2D Localization cross-hairs can no longer be modified or deleted.
