Technical note

How DC3 and GBR differ in practice

DC3 is made of pixels and GBR stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside a GBR container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the DC3 to begin with. A line in a DC3 image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the DC3 does not survive as colour in the GBR.

Smart Workflow

Do more with your DICOM files

Converting DC3 files for easier viewing/sharing? reaConverter offers many additional ways to process DICOM images, so you can customize them according to your requirements.

Our range of editing options includes such image processing actions as Adjust Brightness/Contrast for better clarity, Rotate, Crop, Watermarks to stamp resulted images with DICOM Metadata such as Patient Name, Birthday, Acquisition time and more.

Additionally, opting not to copy metadata ensures that patient information is excluded from the output, helping to protect sensitive data and keep the image anonymous.
