Latest Patents
Among his latest patents is a method for joint arterial input function and tracer kinetic parameter estimation in accelerated DCE-MRI using a model consistency constraint. This method utilizes tracer kinetic models as temporal constraints for highly under-sampled reconstruction of DCE-MRI data. It involves administering a magnetic resonance contrast agent to a subject and collecting data, followed by the application of a selected tracer kinetic model to the imaging data. The method allows for the simultaneous reconstruction of tracer kinetic maps and dynamic images while applying a consistency constraint. This innovation facilitates the use of various tracer kinetic models in estimating patient-specific arterial input functions alongside tracer kinetic maps.
Another notable patent is the method for improved dynamic contrast-enhanced imaging using tracer-kinetic models as constraints. This approach is flexible in handling any tracer kinetic model and does not rely on tuning regularization parameters. Compared to existing compressed sensing methods, it provides robust mapping of tracer kinetic parameters at high under-sampling rates. The method enhances the accuracy of tracer kinetic parameter values and simplifies the reconstruction process, improving the overall quality of the imaging results.
