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 these new filters on images.

CT reconstruction using standard Filtered Back Projection supports various techniques implemented for reducing metal artefacts in CT data. It can hence 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 the publications list.

The locally-adaptive bitonic X filter is described in the publications list.

This is a highly competitive non-learning-based filter for reducing image noise. To implement this filter, set the processing to 'bitonic filter', tick the 'multi-resolution' checkbox and set the data level to four times the noise STD (or tick 'auto'). The filter range should be set to between 4 and 9, depending on noise levels.

For images containing real sensor noise, set the noise to 'sensor noise 1' and make sure that 'auto' is ticked for the data level.

See the documentation for how to use the software.
