Medical imaging

There is provided a method in medical imaging. In the method, a target is imaged with a hyperspectral imaging system (302) in order to obtain imaging data. The obtained imaging data is pre-processed by spatial and spectral averaging (304, 306). A number of endmembers to be determined from the pre- p...

More Information
Summary:There is provided a method in medical imaging. In the method, a target is imaged with a hyperspectral imaging system (302) in order to obtain imaging data. The obtained imaging data is pre-processed by spatial and spectral averaging (304, 306). A number of endmembers to be determined from the pre- processed imaging data is selected. The endmembers are extracted from the preprocessed imaging data based on vertex component analysis (308) on the preprocessed imaging data and the selected number of endmembers, said endmembers defining an extremity of projections of the pre-processed imaging data in a subspace spanned by the endmembers. At least one abundance map is generated (310) of the selected number of endmembers in the pre-processed imaging data using a filter vector algorithm (308) on the extracted endmembers and the imaging data.
