摘要： This application describes an approach to filter, solely in the projection domain, correlated noise from (or de-noise) spectral/multi-energy projection data. As described herein, this can be achieved based at least on variances of the basis material line integrals and a covariance there between, based on multiple correlation coefficients and hyper-planes that describe the noise correlation between different basis material line integrals, and/or otherwise.

摘要： A method includes generating landmarks, for different compositions of materials in scanned structure, wherein a landmark represents a location of a composition of materials, distorted by beam hardening, in a multi-energy Hounsfield Unit space and using the landmarks to perform an image domain material separation and quantification free of beam hardening artifacts.
摘要翻译：一种方法包括为扫描结构中的材料的不同组合产生界标，其中，在多能Hounsfield单位空间中，地标表示通过光束硬化而变形的材料成分的位置，并使用该标记来执行图像域材料分离和定量无束强化伪影。

摘要： A system (SYS) and related method for motion artifact reduction in X-ray imaging. The system (SYS) comprises an input interface (IN) for receiving a first input image (i1, I1) of an object (PAT) reconstructed from a first set of projection data, and a second input image (i2, 12) of the object reconstructed from a second set of projection data. The second set is smaller than the first set. A motion analyzer (MA) establishes an estimate for motion corruption based on the two input images. A selective combiner (Σ) computes an image value for an enhanced image (11+12, i1+i2), based on the motion estimate and on image information in the first input image (i1, I1) and/or the second input image (i2, 12).

摘要： The invention relates to an X-ray imaging device (10) for an object, an X-ray imaging system (100) for an object, an X-ray imaging method for an object, and a computer program element for controlling such device or system and a computer readable medium having stored such computer program element. The X-ray imaging device (10) comprises a receiving unit (11) and a processing unit (12). The receiving unit (11) is configured to receive attenuation data representing attenuation properties of the object for at least two different X-ray spectra. The processing unit (12) is configured to decompose the attenuation data into decomposed data, to reduce noise in the decomposed data to obtain de-noised data, to back-convert the de-noised data into back-converted attenuation data, to combine back-converted attenuation data and the attenuation data into combined attenuation data, and to decompose the combined attenuation data into combined decomposed data.
