5.4 Stereotactic 2D Lesion Targeting
Note
You can use the Zoom tool (in the Tools tab or View Actual Pixels button) to magnify
the area of interest in an image.
Note
If the exam data in the image blocks detection of the lesion, click the Information icon in
the Tools tab to hide the data.
Note
Make sure that the biopsy device is out of the imaging area.
Note
The overall targeting accuracy is equal to the combined targeting accuracy of the Biopsy
Guidance Module and the biopsy device. When using the biopsy device, the maximum
deviation from the target coordinate will not be more than 2 mm from either side.
1. Select the Accept button to save the stereo images.
Note
Your Service representative can configure the system to Auto-Accept new images.
2. Click in the area of interest of the lesion in one of the stereo images.
3. Click the other stereo image, then click in the area of interest of the lesion.
4. Select the Create Target button to save the target. The active target set automatically
transmits to the Biopsy Control Module with the creation of each new target.
5. Repeat this procedure to create multiple targets (a maximum of six).
Note
The target that shows on the Target Guidance screen of the Biopsy Control Module is the
last target created. The target or target set that shows on the Select Target screen is the
last target or target set sent to the Biopsy Control Module.
Note
To target a lesion, you can also use the Scout and one of the stereo images.
