Abstract:
1. A computer implemented method for composing image volumes obtained using a medical scanning device, comprising the steps of: a. using a medical scanning device to obtain data of at least two image volumes of a patient, said image volumes having an overlap region; b. processing the data from the two image volumes to determine the overlap region and to register the two image volumes with each other using rigid registration; c. determining a non-rigid deformation between the two image volumes using an elastic registration algorithm; d. performing an alpha-morphing on each overlapping region of each image volume using the non-rigid deformation by computing first intermediate image volume result I wherein α is a parameter with a range [0.0,1.0] which linearly increases from a top to a bottom of each overlapping region, wherein ø e. obtaining a blend region of the overlap region by performing an alpha-blending which blends the two intermediate image volume results by varying the relative contribution of the two image volumes using the results of alpha-morphing, wherein steps b, c, d, and e are performed by a computer processor.
