Uses of FanProjectors.BremFanParams in jhd.Projection
Methods in jhd.Projection with parameters of type FanProjectors.BremFanParams Modifier and Type Method Description float[]FanProjectors. imageToBremsstrahlungFanBeamSinogram(FanProjectors.BremFanParams ctSet, float[] image, int width, int height)Requires a segmented 2D float image where each material has been assigned an integer tag Requires image pixel size units in CM Requires the chemical formula and density of each tagged component The tags are converted to x-ray cross-sections over a range of x-ray energies Projections are calculated using a simplified Source,Filter,Sample,Detector model The model records photon counts and converts those to measured sample attenuation Used to validate beam hardening correction methods.float[]FanProjectors. imageToBremsstrahlungFanBeamSinogram2(FanProjectors.BremFanParams ctSet, float[] image, int width, int height)Requires a segmented 2D float image where each material has been assigned an integer tag Requires image pixel size units in CM Requires the chemical formula and density of each tagged component The tags are converted to x-ray cross-sections over a range of x-ray energies Projections are calculated using a simplified Source,Filter,Sample,Detector model The model records photon counts and converts those to measured sample attenuation Used to validate beam hardening correction methods.
