Abstract: An object delivery arrangement is disclosed for delivering objects into bone. The arrangement is configured for generating localized mechanical waves into a tissue, for performing localized deposition of the objects near bone, and for exposing the objects and the bone to said mechanical waves to obtain deposition of the objects into the bone.

Abstract: A medical imaging method includes imaging a target with a hyperspectral imaging system in order to obtain imaging data. There is provided a method in medical imaging. In the method, a target is imaged with a hyperspectral imaging system in order to obtain imaging data. The obtained imaging data is pre-processed by spatial and spectral averaging. A number of endmembers to be determined from the pre-processed imaging data is selected. The endmembers are extracted from the pre-processed imaging data based on vertex component analysis on the pre-processed 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 of the selected number of endmembers in the pre-processed imaging data using a filter vector algorithm on the extracted endmembers and the imaging data.
