1. Tab Select Region: Clicking on the various tabs along the top row will bring up the
corresponding set up screen.
2. Unit Set: Allows software to have four (4) different Anatomical Setups. This is
defined as Organ, Sub organ, PM Gain, Offset and selected Filters. NOTE: The filters
can be selected and saved, but not turned on/off using unit sets.
3. Organ List: Selects the major organ category for the current setup.
4. Sub Organ List: Selects Sub Organ category for the current setup.
5. Set New Sub Organ Name: This feature allows for a new Sub Organ category to
be added to any Major Organ Category.
6. Sub Organ Acquisition Setup: This section is used to define the setup of each Sub
Organ. PM Gain and Offset can be freely set at anytime. The grayed out values require
using the “edit” button, which will prompt for a password. Following is a brief
description of each feature.

6. Sub Organ Acquisition Setup: CONT.
• Data Minimum: Is a factor, which is used to enhance the window leveling of the
image.
• PM Gain: Photo-multiplier Gain is a factor which determines how much gain is
applied to the signal received by the photo-multiplier.(Factory Set)
• Offset: Offset is a factor, which is used to eliminate noise from the image. (Factory
Set)
7. Orex Filters Setup: Check the “ON” box to use these filters. Three of these settings
make up an “Unsharp Masking” filter, the remaining one is noise reduction.
• Enhancement: One of three Unsharp Mask Parameters*. Smooth, Kernel and
Enhancement are used together to define how the Unsharp Mask Filter will function.
Enhancement can be set anywhere from 0 – 80.
• Smooth: One of three Unsharp Mask Parameters*. Smooth, Kernel and
Enhancement are used together to define how Unsharp Mask will function. Smooth
can be set anywhere from 0 – 80.
• Noise: This is a noise reduction filter. Noise can be set to either 0 or 1.
• Kernel: One of three Unsharp Mask Parameters*. Smooth, Kernel and
Enhancement are used together to define how Unsharp Mask will function. Kernel
can be set to 3, 5 or 7.
8. Context Vision Filters Setup: Check the “On” box to use these filters. Filters
(also know as GOP) are used for image enhancement.
• Grayed out Window: This indicates which, if any, filter is currently selected.
NOTE: Even if a filter is “selected”, no filter will be applied if the “On” box
is unchecked.
• “SET”: This button will select the current filter in the drop down window below.
The filter will then be displayed in the grayed out window above.
• “CLEAR”: This button will remove the currently selected filter from the grayed out
window, leaving no filter selected.
• Drop down window: This window will show a list of available filters to select from.
9. Advanced Setting: Check the box to activate an option.
• External Settings: This feature allows the use of an external program to select an
Organ, Sub Organ and Scanning Resolution.

1. Data Correction Method: Linearization is used to correct a distortion in the
phosphor plate’s absorption of different energy levels. Choose this method for a more
reliable image; otherwise choose “No Correction”.
2. Image Property: This section defines the two important properties of the image to be
scanned. They are described bellow.
• Fixed Image Path: Defines the location for the Scanner Interface to place the image
Data. This is also where the viewer will retrieve the information. The “Browse”
button can be used to easily find this location.
• Image Format: Allows the selection of three formats for storing the Data.
ο Raw Data Only(16bit): This is the default format and should be used in all
applications.
ο Dent-A-View Image(16bit): This is a format which can only be used by specific
software sets. Use this setting only when instructed by an Orex Technician.
ο BMP(8bit): Use this format to store the image as a BitMap(8bit).
3. Demo Scan: This option will produce a quick demo scan. No exposure or plate is
required when using this option. Very useful for setting up a system and checking data
path.

4. Rotate Canvas: This option is used to change the orientation of the image as
delivered to the viewer.
5. Auto Shutter: This option will apply an automatic shutter to the image to remove any
unwanted white boarders from the image.
6. Small Plate Resolution: The 8” X 10” plate/cassette can be scanned in High
Resolution. Selecting “Always Ask” will prompt the user to select “Normal Resolution”
or “High Resolution” each time an 8” X 10” plate\cassette is loaded into the scanner.
To set the unit for permanent high resolution, check the box next to “Normal Resolution”
you will notice that “Normal Resolution” will immediately change to “High Resolution”.
Note: The “Always Ask” option will override the “Normal\High Resolution”
option.
