    摘要: System (S-SYS) and related method for determining a material density map for a target material. The system (S-SYS) may receive spectral data representable in a two-dimensional data space. The spectral data may include measurements acquired by a spectral imaging apparatus of an object in a three-dimensional image domain of the spectral imaging apparatus. The system determines clusters in the data space, one indicative of the target material, the target material cluster, and clusters indicative auxiliary materials, the auxiliary material clusters. The system may determine a mutual geometrical constellation of the clusters. The system determines the material density map based on the geometrical constellation so determined.

    摘要: The present invention relates to an X-ray imaging system (10), comprising a radiograph X-ray attenuation image acquisition unit (20), at least one sensor (30), and a processing unit (40). The radiograph X-ray attenuation image acquisition unit is configured to acquire a radiograph image of a patient. The radiograph X-ray attenuation image acquisition unit is configured to provide the radiograph image to the processing unit. The at least one sensor is configured to acquire sensor data of the patient. The at least one sensor is configured to provide the sensor data to the processing unit. The processing unit is configured to determine a magnitude and direction of movement of the patient during a time of acquisition of the radiograph image, the determination comprising utilization of the sensor data. The processing unit is configured to post-process the radiograph image comprising utilization of the determined magnitude and direction of movement of the patient during the time of acquisition of the radiograph image.
