Processing Images
You can process an image at any time, either before saving the newly creat-
ed study, or after loading an existing study. Once a study is saved, you will
still be able to open it and make changes to the images in it, but these
changes will be discarded once the study is closed.
During routine operations, the image processing tools are visible all the
time. You can always show the rest of the tools by pressing
Note: Except the Zoom and Annotation tools, settings of all other image pro-
cessing tools can be remembered and automatically applied to the subsequent
images generated afterwards. For example, if you adjust the image brightness
to "4", when you generate another fluoroscopy image, the brightness setting,
level 4 in this case, will be automatically applied to the newly generated image.

Sharpening
An effective sharpening process makes the edges of an image appear suffi-
ciently pronounced, which corrects the blur brought by the camera sensors
and lens and emphasizes the texture, making the image look sharper and
clearer.

Noise reduction
Image noise is random (not present in the object imaged) variation of
brightness or color information in images, and is usually an aspect of elec-
tronic noise. It can be produced by the sensor and circuitry of a digital cam-
era.

Sharpening: (0, 1, 2, 3, 4) The value 0 stands for no sharpening effect is
applied to the image, while 4 means the highest level of sharpening
effect. The default level is 0.
Note:
This feature is only available for the images in the currently
unsaved study.
Take a shot to generate a fluoroscopic image.
On the control screen, press Sharpen

One click or tap increases the sharpening level by 1.
The sharpening level reading is displayed above the tool button in
