Brain tissue classification

A computer program embodied on a computer readable medium for medical imaging processing, comprising:

• code that uses an imaging method to acquire at least first and second data sets of a region of interest of a patient's body, with at least one image acquisition parameter being changed so that first and second data sets yield different contrast levels relating to different substance and/or tissue types, and wherein the at least one acquisition parameter used to obtain the first data set is selected to enhance the contrast between one of the substance and/or tissue types relative to other substance and/or tissue types, and the at least one acquisition parameter used to obtain the second data set is selected to enhance the contrast between a different one of the substance and/or tissue types relative other substance and/or tissue types, thereby to optimize the contrast between at least three different substance and/or tissue types;
• and
• code that processes the two data sets to identify the different tissue types and/or boundaries therebetween.

A medical imaging processing method comprising:

• obtaining at least first and second data sets of a region of interest of a patient's body that have been produced by an imaging method, with at least one image acquisition parameter being different such that first and second data sets yield different contrast levels relating to different substance and/or tissue types, and wherein the at least one acquisition parameter used to obtain the first data set enhances the contrast between one of the substance and/or tissue types relative to other substance and/or tissue types, and the at least one acquisition parameter used to obtain the second data set enhance the contrast between a different one of the substance and/or tissue types relative other substance and/or tissue types;
• and
• processing the two data sets to identify the different tissue types and/or boundaries therebetween.
