Abstract: The present invention refers to providing a system that allows to very accurately determine the state of a disease, like COPD, in a patient. The system (100) comprises a unit (101) for providing images of the region of interest corresponding to different states of the region of interest, a unit (102) for elastically registering the images to each other resulting in an elastic registration output, a unit (103) for determining a specific tissue region in an image, a unit (104) for determining a specific elastic registration output for the specific tissue region based on the determined elastic registration output, and a unit (105) for determining an elastic indicator for the specific tissue type based on the specific elastic registration output. Thus, a state of a disease that influences the elastic properties of the specific tissue type can be determined very accurately.

Abstract: A system (100) includes an imaging system (102) and a pressure delivery system (104). The imaging system includes a data acquisition system (114 and 116) and is configured to produce data. The pressure delivery system is configured to produce a periodic airflow variation. The system further includes an operator console (120) configured to control the imaging system to scan a subject receiving the periodic airflow variation and map the periodic airflow variation and first data. The system further includes a reconstructor (516) configured to reconstruct the first data and generate first volumetric image data indicative of the periodic airflow variation.

Abstract: The invention relates to a method of MR imaging of an object (10). It is an object of the invention to enable MR imaging using the stack-of-stars or stack-of-spirals acquisition scheme providing an enhanced image quality in the presence of motion. The method of the invention comprises the steps of:—generating MR signals by subjecting the object to an imaging sequence comprising RF pulses and switched magnetic field gradients;—acquiring signal data according to a stack-of-stars or stack-of-spirals scheme, wherein the MR signals are acquired as radial or spiral k-space profiles from a number of parallel slices arranged at adjacent positions along a slice direction, wherein a central portion (20) of k-space is more densely sampled during the acquisition than peripheral portions (21) of k-space;—reconstructing an intermediate MR image (22-25) from sub-sampled signal data for each of a number of successive time intervals;—deriving motion induced displacements and/or deformations by registering the intermediate MR images (22-25) with each other; and—combining the sub-sampled signal data and reconstructing a final MR image therefrom, wherein a motion correction is applied according to the derived motion induced displacements and/or deformations. Moreover, the invention relates to a MR device (1) and to a computer program for a MR device (1).

Abstract: The present invention relates to device and method for correction of a medical breast image. To provide for an improved correction, said device comprises a medical image input (31) for obtaining a medical breast image of subject's breast potentially showing artificial deformations of the breast, a scan image input (32) for obtaining a scan image of the same subject's breast showing the breast in a predetermined position of the subject and comprising surface information of the breast, a simulation unit (33) for generating a simulated medical breast image from the obtained medical breast image, said simulated medical breast image showing the breast in the same predetermined position of the subject as the scan image and representing the breast surface by a surface mesh, wherein said simulation unit (33) is configured to generate said simulated medical breast image based on a volumetric biomechanical model, and wherein material parameters of the biomechanical model are varied for aligning the biomechanical model with the breast surface extracted from the scan image, and a correction unit (34) for determining corrections for correcting the simulated medical breast image for said artificial deformations by use of the scan image by applying a surface matching between said surface mesh and said scan image and for applying the determined corrections to the obtained medical breast image to obtain a corrected medical breast image.
