Latest Patents

One of Chan's latest patents is titled "Method and apparatus for small pulmonary nodule computer aided diagnosis from computed tomography scans." This invention features a multi-stage detection algorithm that employs a successive nodule candidate refinement approach. The detection algorithm consists of four major steps. First, a lung region is segmented from a whole lung CT scan. This is followed by a hypothesis generation stage in which nodule candidate locations are identified from the lung region. In the third stage, nodule candidate sub-images pass through a streaking artifact removal process. The nodule candidates are then successively refined using a sequence of filters of increasing complexity. A first filter uses attachment area information to remove vessels and large vessel bifurcation points from the nodule candidate list. A second filter removes small bifurcation points. This invention also enhances the consistency of nodule segmentations by utilizing rigid-body registration, histogram-matching, and a rule-based adjustment system to eliminate missegmented voxels between two segmentations of the same nodule at different times.
