The image processing device (10) comprises a data input (11) for receiving spectral computed tomography volumetric image data organized in voxels. The image data comprises a contrast-enhanced volumetric image of a cardiac region in a subject's body and a baseline volumetric image of that cardiac region, e.g. a virtual non-contrast image, wherein the contrast-enhanced volumetric image conveys anatomical information regarding coronary artery anatomy of the subject. The device comprises a flow simulator (12) for generating, or receiving as input, a three-dimensional coronary tree model based on the volumetric image data and for simulating a coronary flow based on the three-dimensional coronary tree model. The device comprises a perfusion synthesis unit (13) for generating a perfusion image representative of a blood distribution in tissue at at least one instant in time taking at least the baseline volumetric image and said coronary flow simulation into account.

摘要： In breast tomosynthesis/mammography, the breast is compressed in cranial- caudal direction and X-ray images are acquired of the compressed breast. For diagnostics, a sample of the breast can be taken with a biopsy needle using X-ray guidance. In the lateral approach, the biopsy needle is inserted perpendicular to the cranial-caudal direction of breast compression. In this invention we propose a lateral compression unit, which avoids movement of the breast when inserting the needle. Furthermore, the insertion length for the needle can be reduced with a height-adjustable lateral compression paddle and a dedicated spot compression mechanism.

摘要： An imaging method includes obtaining projection data for a helical scan of a subject. The method further includes reconstructing, for a particular time and image slice location of interest, a first temporal motion state image at an earlier time on the detector array and offset from the central row in a first direction with projection data from a first subset of detector rows, and reconstructing, for the particular time and image slice location, a second temporal motion state image at a later time on the detector array and offset from the central row in a second direction with projection data from a second different subset of detector rows. The method further includes estimating a distortion vector field between the first and second temporal motion state images, and constructing motion compensated volumetric image data with a motion compensated reconstruction algorithm using the distortion vector field to compensate for arbitrary motion.
