Latest Patents

Negahdar holds a patent for a "Volumetric deformable registration method for thoracic 4-D computed tomography images and method of determining regional lung function." This patent describes a method of deformable image registration for thoracic 4-D CT images. The process involves receiving a set of thoracic 4-D CT images and iteratively solving an energy function applied to these images. The energy function enforces constraints such as intensity constancy, mass conservation, gradient constancy, and spatio-temporal smoothness. Additionally, the method includes determining regional lung function by transforming the 4-D CT images into spatial voxel-wise deformation maps and strain maps, which indicate the regional mechanics of the lung.
