The software provides various tools to control various image attributes or parameters, x-ray
acquisition, image views, image tools, and DICOM settings/access. The most commonly used
tools are in a Tool Bar. The Tool Bar and Menus are described in more detail in the following
pages.
The software provides single click access to a number of commonly used tools or functions with
a vertical tool bar located on the left side of the screen. More detailed descriptions follow in the

Enhance Image (2D Image Mode Only)
The button shown will process the image on the display to emphaize the smaller
details, such as micro-calcifications, and small masses in the image.
The algorithm, commonly known as “Peripheral Equalization” or “Thickness
Equalization” in advanced imaging, is applied to the whole image. In addition to this algorithm,
Faxitron employs a second, internally developed algorithm called the “Calcification Emphasis”
algorithm. This secondary alrorithm is made to bring out small details in the image and make
them much easier to see and analyze.
Since Patient images constitute a more general category, in terms of possible geometries and
variety of thickness, there may be some challenging sample geometries, and the user should
use this tool with care.
The system will be idle (in Standby) during the processing. Once completed the button will stay
depressed/active. The user can undo the process by pressing the button again.
