Assignee: KING'S COLLEGE LONDON
Field: Measurement (Instruments)
Classification: CPC G  A | IPC A  G

Claim 18:
19. Apparatus for analysing a functional magnetic resonance imaging (fMRI) scan representing a time-sequence, comprising t time points, of images comprising v voxels, where each scan can be represented by a data matrix X∈t×v the apparatus including a computer processing system configured to:
model the scan data X as the convolution of a neural activation time course N∈+t×v and a haemodynamic filter Ψ, and
perform an inverse operation with respect to Ψ and a matrix decomposition into multiple brain network components using a matrix H defining, for each component, a spatial map of the voxels belonging to that component, to derive for each component, the time sequence of activation of that component during the scan.
