wxDicom v2.4 Overview

wxDicom was originally written as a simple tool to demonstrate various image interpolation and filtering techniques in a teaching setting. It has since been expanded to allow it to load medical data from various sources (including DICOM) in addition to several standard image formats. Since it can also save sequences of images, it can be used to load, process, then save DICOM data to a standard image sequence.

Several of the filtering techniques were developed by the author, and hence the software can be used as a way of investigating the effects of this new filter on images.

wxDicom Bitonic Filtering

The Structurally Varying Bitonic filter is described in a technical report [1].

wxDicom Bitonic Filtering

The Bitonic filter is also described in a technical report [2].

wxDicom Refined Metal Artefact Reduction

More recently, CT reconstruction using standard Filtered Back Projection has been added, in order to support various techniques for reducing metal artefacts in CT data which are also implemented. It can hence also be used to test the newly developed Refined Metal Artefact Reduction (RMAR) on CT data in a DICOM format, and can create new DICOM files with this technique applied. The RMAR technique is described in a technical report [3].
