  • Patent number: 10970926
    Abstract: A system obtains multiple x-ray measurements corresponding to different breathing phases of the lung by determining, based on a volumetric measurement of the patient's breathing, a breathing phase of the patient and gating an x-ray imaging apparatus to produce an x-ray projection of the patient's lung when the breathing phase matched any of a plurality of different breathing phases. The system extracts multiple displacement fields of lung tissue from the multiple x-ray measurements corresponding to different breathing. Each displacement field represents movement of the lung tissue from a first breathing phase to a second breathing phase and each breathing phase has a corresponding set of biometric parameters. The system calculates one or more biophysical parameters of a biophysical model of the lung using the multiple displacement fields of the lung tissue between different breathing phases of the lung and the corresponding sets of biometric parameters.

Volumetric 3D image reconstruction and dual or triple energy 3D image decomposition can be executed using data from the CBCT scan. The invention allows for a variety of selections in energy and filtration associated with each source and the order of pulsing for each source (“firing pattern”). The motivation for distributing the sources along the z direction in CBCT includes extension of the longitudinal field of view and reduction of cone-beam artifacts.

    Abstract: A dynamic CT imaging method is provided. With the method, projection measurement data for a region of an examination object to be imaged is captured, with simultaneous correlated capture of the respiratory movement of the examination object. A phase of the respiratory movement, for which image data is to be reconstructed, is selected. Phase projection measurement data assigned to the selected phase is also determined. Transition regions of partial images of the region to be imaged between successive respiratory cycles are then reconstructed on a trial basis based on a part of the phase projection measurement data, and a standard reconstruction is performed using parts of the phase projection measurement data for each of the successive respiratory cycles assigned to an optimum reconstruction.
