    摘要： Disclosed is a method for reconstructing a matrix image representative of a static scene under predetermined lighting conditions, including: —acquiring images, captured by a sensor using a lighting which is separate from one image to another; and —reconstructing the matrix image, in a reconstruction space separate from a native spectral space of the sensor, by determining, for each pixel, the spectral components by weighted combination of the spectral components of the native spectral space of the image sensor, the spectral components being photometrically adjusted and associated with the same pixel of each image of the captured images. the weighting is obtained by solving a linear equation system having at least the following parameters: a predetermined value matrix associated with the predetermined lighting conditions, a matrix representative of both the spectral response of the sensor and the spectral distribution of each lighting applied to each captured image.

    摘要： A projection method of three-dimensional imaging includes the steps of respectively projecting a radiation field emitted from a radiation source with respect to one specific detector of a plurality of detectors and a three-dimensional sub-voxel onto two two-dimensional planes; rotating the specific detector to one specific axis of the two dimensional plane; performing a calculation for obtaining a sub-geometric factor corresponding to each specific detector and each voxel; and, finally, forming a geometric factor by combining each sub-geometric factor defined by each detector and each voxel.

    摘要： A method and system for high-resolution and parallelizable data processing, reconstruction, and deconstruction, uses arbitrary frequency-space (FS) or inverse frequency-space (IFS, such as image, audio, or video space) sample points in N dimensions. According to a preferred embodiment of the invention, a subset of optionally pre-processed and/or pre-conditioned N-dimensional FS data (or IFS data) is acquired (102) by a processing device (360), the data is optionally transformed (115) by “region scaling factors”, and the data is optionally reduced (116) in numerical significant digits. A “horizontal key” of data elements is calculated (120) on a processor (361), preferably in parallel, for each of an arbitrary set of x-coordinates in IFS (or FS). IFS “color” data (or FS data) are calculated (130) on a processor (361), preferably in parallel, at the x-coordinates corresponding to the horizontal keys. The IFS coordinates (or the FS coordinates) are arbitrary, and the reconstruction's calculated IFS data (or the deconstruction's calculated FS data) are optionally rotated or transposed (141) (such as for display purposes), and are thus formed (150) in a memory (363) or on an output device (365). The method can be applied to other subsets, such as in the N-dimensional case.

    摘要： The X-ray CT apparatus includes an X-ray tube, an X-ray detector, a rotation unit, a data generation unit, an image generation unit and a setting unit. The data generation unit generates data used in reconstruction processing of a CT image on a basis of an output of the X-ray detector. The image generation unit performs reconstruction processing of the CT image, the reconstruction processing using the data and a parameter value relating to at least one of an FDD and an FCD. The setting unit sets the parameter value used in the reconstruction processing using the data generated when the X-ray is emitted to the object, the parameter value being set based on CT values of a plurality of CT images obtained by a plurality of parameter values used in the reconstruction processing using the data generated when the X-ray is emitted to a phantom.
