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.

An X-ray imaging system (100) includes an X-ray source (110), an X-ray detector (120), a depth camera (130), and a processor (140). The processor (140) receives depth camera image data from the depth camera, projects the depth camera image data onto a radiation-receiving surface of the X-ray detector (120), from a perspective of the X-ray source (110), and generates an image representation (170) of the projected depth camera image data on the radiation-receiving surface of the X-ray detector (120), from a perspective of the depth camera (130).
摘要:
The disclosure relates to an X-ray imaging system for acquiring two-dimensional or three-dimensional images of a subject. A relative position of an X-ray emitting region, as seen in a coordinate system which is stationary relative to an anti-scatter arrangement and/or an X-ray sensitive surface is controlled so that a first and a second image are acquired at different relative positions of the X-ray emitting region relative to the anti-scatter arrangement and/or the X-ray sensitive surface (10). A data processing system of the imaging system generates an output image, based on each of the images. In the output image, artefacts generated by the anti-scatter arrangement, are reduced, suppressed or eliminated compared to the first and the second image.
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.
