Use the Zoom True Size tool to display the image at its actual size, according to available image information.
If you have calibrated the image, the calibration factor is used to determine the actual size.
If not, DICOM pixel spacing determines the actual size, if available (as it typically is with CT and MR images).
Otherwise, if an Estimated Radiographic Magnification Factor (ERMF) is available and enabled, it is taken into account in presenting XA, RF, DX, and MG images at actual size.
 | Note: Mammography images displayed at actual size are chest wall aligned. |
To display the image at its actual size
From the Image area top toolbar, Zoom button menu, select Zoom True Size.
If not enough information is available to display the image at true size, an icon is displayed beside the pointer, and the zoom cannot be applied.
Click the image to magnify.
The image is displayed alone at its actual size, overriding the selected screen format.
To return to the previously displayed size and layout, right-click.
