While Dentiray Capture does it's best to read the information given to it by the sensor, occasionally a little something gets lost in translation and we have to step in to add a procedure to our acquisition process to help images display as they should. In Dentiray Capture, we call these procedures Post Capture Filters.
A Post Capture Filter is a filter attached to a device in Dentiray Capture that will automate a procedure such as rotating an image or flipping it (to reverse a mirror effect). Post Capture filters can also apply brightness, contrast, sharpening and a few other effects. Here will will focus on image orientation.
Example Issue: My Panoramic X-rays always come out upside down and we're always having to rotate them to make them right side up.
Solution in Steps:
1. Enter Dentiray Capture
2. Select Advanced User Tools>>Preferences (Password = AKRON)
3. Select Imaging Extensions on the left
4. For Direct Devices - Expand Digital Xray Image Capture / For TWAIN devices - Expand General Image Capture
5. Select the Manufacturer of the Device / If TWAIN device, select TWAIN Capture Acquisition
The type of device you choose should correlate directly with what device you select when you take the images. If you select TWAIN to take a Pano, your Pano is using the TWAIN interface. If you select Planmeca to take a Pano, you are using a direct interface and would want to select Planmeca under Digital Xray Image Capture. For my example I have selected TWAIN Capture Acquisition as that is most common.
6. Select Modify Post Capture Filters
7. Select Filter Options>>Add New Filter>>Select Appropriate filter - In this case - Rotate 180 Degrees Filter
If your images are coming out mirrored (right is left, left is right) you'll want to apply the Flip Horizontally Filter (this is common with ScanX Images). If up is down and down is up in your images, you'll want to apply the Flip Vertically Filter.
8. Verify the filter was added to the list of applied filters
9. Select OK, then OK on the following screen, then OK on the last screen - this will take you back to the Main Menu.
This will now start rotating my TWAIN acquired Pano's 180 degrees as the image is collected from the sensor so that you will no longer have to do it manually for each image.
Expanded Examples
This image is properly orientated. Note the positional marker is in the correct place and is legible.
This Image is upside down as indicated by the upside down L positional marker. To correct this image we would need to Rotate 180 degrees Filter
Notice how the positional marker is a backwards L and it's in the opposite corner from where it should be. This indicates the image is mirrored and to correct we would want a Flip Horizontally Filter.
This image is both mirrored and upside down as indicated by the upside down, backwards L positional marker. We can quickly correct this by applying a Flip Vertically Filter.
