 This widget contains the parameters that control the digitization of POIs in the X-ray images. When you are digitizing POIs in the images, there are two methods of determining the XY coordinates in the 2D images, which are then used to calculate the 3D position in the X-ray lab frame. The recommended method is to left-click on any portion of the POI in the image and let Locate3D calculate the weighted center of pixels representing the POI. This process is described in detail in [[Other:DSX:Locate3D:Locate3D_Overview#Digitizing_POIs|Digitizing POIs]], and is governed by the parameters listed below. For cases in which this process does not correctly locate the POI center (e.g., non-circular POIs), you can use Ctrl-left-click to specify the point. In this case Locate3D will use the exact XY coordinates of where you clicked as the 2D location of the POI in that view.

   * **POI Scale** used to calculate the expected radius, in pixels, of the POI in the X-ray images. The expected radius is the physical size of the POI multiplied by the scale factor, divided by the pixel size. The scale factor should increase with the distance between the POI and the image plane.
