ANALYSING MRI DATA TO DETERMINE TUMOUR TYPE

摘要

There is provided a method of analysing MRI data of a tumour in order to determine the tumour type. In one arrangement, the method comprises segmenting the MRI data to identify tumour voxels and non-tumour voxels; processing a plurality of slices of the MRI data in order to obtain, for each slice, values of a plurality of different shape parameters, each shape parameter describing an aspect of the shape of a region containing the tumour voxels within the slice; for each shape parameter, analysing a distribution of values of the shape parameter over the plurality of slices to obtain a value of a shape feature that is characteristicof the tumour shape; and determining the tumour type using the obtained shape feature values.
