"Depending on image type"

This function allows for theconfiguration of exposure sequences.

By clicking the different buttons (individually or in combination), you can determine the image type(s) for which the selected settings are active.

"Depending on image type" / Value range of X-ray exposures The control box "16 bits" helps process and manage newly generated X-ray exposures with 16 bit depth.

NOTE:

The compression of X-ray images with a bit depth of more than 8 bits is not currently supported.

"Depending on image type"/ "Single exposure sequence"

z The option "Set tooth or program before exposure"

activates or deactivates the automatic query of the target area to be exposed (tooth type,region, or program). When it is active, the user is asked to specify the target area immediately before taking the exposure, provided that it is not known already (e.g. from an incoming X-ray order).

The findings dialog box is displayed for this purpose and must be confirmed before the system is ready for exposure. SIDEXIS can use this information to display the image in the anatomically correct orientation and position.

z The option "Automatic image description after exposure"

activates / deactivates the automatic findings function for all X-ray exposures. When it is active, the user is prompted to enter the findings in the dialog box which is displayed immediately after taking the exposure.

"Depending on image type" / "L/R marking"

This function determines whether a tooth position marker is to be inserted into the image.

"Depending on image type"/ "Compression"

z If the option "Compress immediately" is activated, the image is compressed immediately after exposure.

As X-ray and video exposures take up quite a large amount of storage space when they are saved to hard disk or MO disk, SIDEXIS offers the option of compressed storage. The amount of disk space required by the exposures can be greatly reduced in this way.

CAUTION: About L/R markers on images of the XC type If the optional marking of the image with the letters R and L is activated in SIDEXIS, an R will always be inserted in the lower right corner of the image when taking cephalometric images. This may lead to confusion. This marking is not comparable to the well-known R/L markers of conventional images.

On all cephalometric images, the R marker does not refer to the X-ray beam direction, but ensures that the image is viewed in its original orientation and not flipped.

z The compression factor is set in the "Compression parameter" box.

When using the SIDEXIS JPEG compression, image information is lost depending on the selected compression factor.

In order to limit the loss of image information, the following limit values apply for setting the compression factor:

The table below shows the compression rates to be expected with various compression factors.

The time required for compression and decompression procedures depends on the system performance and therefore plays a less significant role on fast PCs.

z Explanation

Depending on the image type involved, there are certain settings that are useful for diagnostic image display.

The possibility of having these settings performed automatically by SIDEXIS XG in the screen display of the corresponding image type has been created here.

z Structure

The following screen displays can be set depending on the image type:

Image type Permissible setting range for

Compression factor Intraoral X-rays Panoramic X-ray

100 approx. 1.5 to 2 approx. 2 to 3

90 approx. 5 to 8 approx. 10 to 18

80 approx. 9 to 13 approx. 22 to 33

CAUTION:

This configuration window is used only to optimize the screen display of X-ray and video exposures.

The image data in the SIDEXIS XG database are not changed.

- "Filter"

Up to three filters can be specified for the screen display here.

Three list boxes are available for this purpose.

The list boxes are processed from top to bottom.

Example:

After an image view has been optimized with the "Sharpen" filters, the "Reduce noise (median)" filter is used to reduce the increased noise level of the image view.

- "Settings"

- "Brightness"/ for brightness settings.

- "Contrast"/ for contrast settings.

- "Zoom"/ for display settings - Control box "Yes"

The settings are activated for the corresponding image type by selecting the "Yes" check box.

"Configure"/"Template..."

Starts the configuration workspace for exposure templates that can be used for exams. See Section "Editing an exposure template [ 147]".

"Usual X-ray tube settings (intraoral radiography only)"

The text boxes"Tube voltage in kV" and "Anode current in mA"

show the customary settings for the tube assembly used for the intraoral X-rays. These values are required exclusively for documentation in the image database.
