Medical Image Analysis Sub-Tools

These tools are intended for the quatitative analysis of medical images. All of them have either been used, or are being used, in medical research projects.

• NMR-Segment: nmr_segment_tool()

  This tool has been developed to identify tissues in MR data sets. The approach uses EM modelling based upon Bayes statistics. Its is expected to be used in conjuction with the Sequence and Imcalc tools.

• NMR-Analysis: nmranalysis_tool()

  This tool has been developed for the analysis of temporal MR data sets, such as BOLD, Perfusion and Permeability analysis. Its is expected to be used in conjuction with the Sequence, Imcalc and Coreg tools.

• Coreg: coreg_tool()

  This tool is used to co-register and reslice, either manually or automatically, MR data sets. It is designed to be used in conjunction with the Sequence tool.

• SmartROI: sroi_tool()

  The SmartROI Tool is designed to support the automatic location of simple polygonal boundaries in grey level data. The techniques are based on eigen vector approximation to sampled data. The tool can be used in conjuction with the Imcalc, Sequence and Mono tools. Located structures can be used to define local regions away from the main control points using an method of affine transfer.

• SeqROI Tool: seqroi_tool()

  This tool is provided for manipulation, visualisation and storage of 3D volumes of interest. It allows the editing of a set of closed 2D spline curves which can be viewed in the threed Tv and apllied as regions of interest in other Tv's. The tool also has use for maual markup of structures.
