Image functions
You can customise the image to your needs, using the tools available in “Image control”.
Scrolling Function of the scroll wheel. Hold down the left mouse button and move the cursor over the image. You can now scroll through the series.
Region zoom Zoom in on a specific region.
Stepless zoom Zoom in on the image without intermediate steps.
Zoom out Zoom out.
Pan/Select You can still drag the image even if you’ve zoomed in on it.
Density measurementSelect this function and hold down the left mouse button to measure the density in Hounsfield units (HU), optical density (OD) or unspecified units (US).
Spacial locator This function is used to navigate to the same reference point in series. It only works for CT and MRI images.
Cine loopUse this function to automatically scroll through all images without actually using the scroll wheel. The used frame rate is the value, specified in DICOM Tag RecommendedDisplayFrameRate.
In case this value is not available, by default a frame rate of 30 fps is used. You can also adjust the scrolling speed yourself.
Auto link series Different series with the same "frame of reference" are linked automatically for simultaneous scrolling.
Reference linesThis tool is activated by default and uses lines to indicate the position of the selected image compared to another series. This tool only works for CT and MRI images.
