Latest Patents

Cao's latest patents include a more efficient method and apparatus for detector response correction and material decomposition of projection data obtained using photon-counting detectors. This invention focuses on processing X-ray projection data, including spectral computed tomography (CT) projection data. The method involves decomposing spectral CT data into material projection lengths using a material-decomposition technique that incorporates an initial-estimate method. This method reconstructs an image using non-spectral CT data and subdivides it into materials based on relative attenuation density. The projection length estimates for each material are obtained through forward projection of the corresponding subdivisions. Additionally, the initial estimate can be refined by selecting projection lengths with the smallest cost-function value from a sample space, conditioned on the X-ray flux at the source.

Another notable patent is the polar effect model, system, and method for photon counting detectors in medical imaging systems, including computed tomography. This invention provides an apparatus and method for calculating the output spectrum of a photon-counting detector based on an incident spectrum. The system includes processing circuitry that determines a plane extending from the detector's top face, divides it into subregions, and calculates a detector response function for each subregion. The overall detector response function is then determined by summing and normalizing these functions, allowing for accurate output spectrum calculations.
