System and method for generating perfusion functional maps from temporally resolved helical computed tomographic images |
| abstract |
Various methods and systems are described for obtaining at least one CTA perfusion functional map from Time Resolved Helical CTA (TRH-CTA) image data. At least one processor may be configured to preprocess the TRH-CTA helical image data to generate preprocessed TRH-CTA helical image data; generate time density curve data for a plurality of voxels from the preprocessed TRH-CTA helical image data foran axial imaging slice, where the time density curve data comprise intensity values for different phases of the preprocessed TRH-CTA helical image data arrangedsequentially in time; generate at least one perfusion functional map for the axial imaging slice by at least one of: (1) applying at least one mapping function to differentphases of the time density curve data corresponding to the axial imaging slice; (2)applying a deconvolution method to the time density curve data; and (3) applying anon-deconvolution method to the time density curve data; and perform spatial filteringon the perfusion functional map. A display may be used to display at least one filtered perfusion functional map. |
