This
document is specific to the USB model of the ScanX.This document is intended to help setup the ScanX system within XrayVision® (XV). Select a topic below or scroll down for complete instructions:
If the computer does not have XV installed already, the first step is to install the software. Refer to the following KB article for instructions, if needed: HOW TO: Install or Upgrade Apteryx Imaging Software.
At this point, a decision needs to be made whether the software should be installed locally on the ScanX computer or on the server. It is recommended to install the software on the server, so that all computers can access it.
Note: The trial versions of Apteryx software will run for 30 days on up to 3 computers in a network environment.
This
document is specific to the USB model of the ScanX.
Now that the software is installed, it is time to install the ScanX.
Turn on the ScanX and attach the USB cord to the computer and ScanX. You will see a "New Hardware Found" wizard.
Insert the ScanX driver CD, and make sure "Install the software automatically (Recommended)" is selected, then click Next. You will most likely be prompted to do this three times.
Once the ScanX is installed, check that it is installed by looking in Device Manager. Right-click the My Computer icon and choose Properties. On the 'Hardware' tab, select Device Manager. The ScanX will appear under "X-ray Imaging devices".
On the Air Techniques CD there is a Demo program which should be installed. This small diagnostic utility will assist any support personnel in diagnosing problems.
If
the Air Techniques CD is not available, Apteryx has the driver and Demo program
available at ftp://files.apteryx.com/
in the ScanX directory, listed
as Device Drivers.zip and Demo
Program.zip.
Since Apteryx Imaging is modular in nature, Apteryx always suggests running the latest updates off the web for the hardware being used. Here is the link for the ScanX upgrader: http://www.apteryxware.com/dental/downloads/xva3_5/airtech.shtml
Air Technique's, the manufacturer of ScanX, recommends the installation and enablement of an image processing utility called Dynamic Rendering. Dynamic Rendering is an image processing technique that works with the ScanX and third-party imaging systems to improve the quality of the images as they are acquired in order to reduce or eliminate the need for any post-acquisition processing. By default, when the ScanX interface library is updated, Dynamic Rendering is enabled for most imaging software, including Apteryx's XrayVision. A utility is also provided to enable (or disable) Dynamic Rendering found under the Windows Start > Programs > ScanX Utilities menu.
In order to make full use of Dynamic Rendering, Air Techniques suggest the settings below to be configured in XrayVision's ScanX Digital Xray Options screen.
To access the image settings for the ScanX, select Tools > Imaging Device Extensions from the main menu. Double-click on the ScanX option on the list.
On the 'General' tab, select the following checkboxes:
'Invert the images' (makes the dense areas white, and the non-dense areas black on the image).
'Flip pan and ceph images' (flips images right to left so the L and R are correct.
Enter the following values for the 'Per GBC' tab:
'Brightness' = 0
'Contrast' = 0
'Gamma' = 0.80
'Equalize' = unchecked
The 'Ceph / Pan GBC' tab controls all the values for the extraoral films. Enter the following values for the this tab:
Brightness = 0
Contrast = 0
Gamma = 0.80
Equalize = unchecked
Click OK to save the changes.
Open XV, select Open Patient and select a test patient (Jane or John Doe). Once the patient is open, images will be automatically saved in their account.
The
open patient's name will be displayed on the title bar of the application.
There are two ways to capture scanned images in Apteryx software, either Capture Layout which is similar to plastic mounts used for film-based X-rays, or Capture Single which is useful for pans and a quick PA.
If the user wants to scan into a layout, you must edit the layouts first to accept images from a Scanner (by default layouts are set to capture from a sensor). To edit the Layouts, click on the Capture Layout button, then click on the Edit Layout Definitions button to open the Layout editor.
To edit a layout, the layout must first be selected from the list on the left. Once a layout is selected (4 Bite Wings are selected in the example above) click on the 'set all tiles to the same source' button.
The 'Take From' window will appear; choose 'Scanner' from the list, click OK. This must be repeated for every layout the office will want to use.
If
the office plans on using sensors and a scanner, the layouts need to be
modified for scanner but re-saved under a different name, so that the office
can choose between a sensor layout or a scanner layout.
In the example above there is a '2 Bite Wings' and a '2 Bite Wings_Scanner'. This is accomplished by modifying the source to scanner then clicking 'Save As' and entering the correct name.
The order in which the images will be captured into the layout can be changed in the 'Edit Layout Definitions' screen by clicking on the 'Order' button with the appropriate layout selected. Once 'Order' is clicked, click on the tiles in the desired order; all tile must be clicked on - the tile numbers will change as the tiles are clicked.
Simply click on the Capture Single Icon detailed above. This will bring you to the 'Capture Image' screen. You will also come to the 'Capture Image' screen when doing a layout.
Select ScanX as the source. The rest of the options affect the category in which the image will be placed. 'Image Type' sets the type of image - this is used to filter images. 'Image Subtype' is a lower level label. 'Resolution', ' Media Type', and the Color selection buttons are for Flat Bed scanners and are not going to affect the ScanX images - these can be ignored.
Click on the Capture Layout button, select the appropriate layout from the list, and click the Capture Series button. When scanning into a layout, the first film put into the ScanX - no matter what slot (1-4) - will be placed into tile 1, the second into tile 2, etc.
Once the OK button is pressed in the 'Capture Image' screen, the 'Air Techniques ScanX' window will open. At this point, the green lights on the scanner will turn on indicating the ScanX is ready for films to be scanned.
It is important to select the appropriate 'Film Type' in this window, Intraoral Standard and Extraoral Standard are the most common. Check with the manufacturer for specifics on what film type should be used with the plates received. This setting changes the scanner resolution settings and greatly varies file sizes.
Once the images are done scanning, they will appear as a preview in the 'Air Techniques ScanX' window under the 'Scanned Images' area. Once the Done button is clicked, the images will transfer back into Apteryx Imaging software, either as a single image or into the tiles of a layout.
If scanned into a layout the images may need to be moved from one tile to another.
It is recommended to move the images to the appropriate tile by dragging them from one tile to another, before clicking Done in the software.
Once Done is clicked, the images can be flipped, rotated, and moved.
Notice the small stack of paper in the lower right-hand corner of the first 3 images above, but not on the last image. This is an indicator that there is more than one image in that tile. It is possible to have the images stacked up. When this indicator appears, it can be clicked so that the appropriate image can be selected. Treat these images as a stack of cards; only the top image can be manipulated or moved.
To flip or rotate an image, go to 'Image' on the main menu, and choose 'Flip' or 'Rotate'.
To move an image to another tile, click on the move image icon, or right-click on an image and select Layout Options > Move Current Image to a Different Tile.
The flip and rotate commands can be added to the toolbar of the main program to make it easier for the user to access them. Refer to the following KB Article for detailed instructions: HOWTO: Add Commands to the Toolbar.
Typically if the scanner does not work in XV, it is recommended to test it in the Demo scan software distributed by Air Techniques. If the scanner does not work in either software, there is most likely a problem with the connection of the ScanX to the computer, or a problem with the driver in Windows.
Some things to check:
The connection of the USB cable
Scanner is powered on
ScanX is listed in 'Device Manager'
If the ScanX setup appears to be fine but still does not work, try a different USB port on the computer, most likely it will prompt you for the driver to be installed again.
There are very few files that control the ScanX through XrayVision. A lot of the files are provided by Air Techniques, and are common among programs. This can be useful if the scanner is working in the Demo scan program but not in XrayVision.
First, download and install the latest Library Update from Air Techniques' website; this should be installed on the workstation that is connected to the ScanX.
Locate the Demo scan install folder (typically C:\Program Files\Air Techniques, Inc\DemoScan) and copy the VistaScan.dll and VistaScan.ini to the main directory of XrayVision. Windows should prompt you to overwrite the existing files when copying the new one, answer Yes.
Navigate to the Windows directory (C:\Windows) and copy LIBFFTW3-3.DLL to the XrayVision directory.
If the ScanX does not appear in the list of devices in XrayVision, this typically means that the module for ScanX is not installed. The file called ScanX.iddll should be in the main directory of XrayVision; this file is installed by our ScanX upgrader, or from the Apteryx Imaging CD during installation if 'ScanX' is selected. If this file is present in the main directory of XrayVision or XVLite, the ScanX will be in the list of devices. To remove the ScanX form the list of devices, simply locate and delete the ScanX.iddll file.
