Abstract: An Image processing system (IPS) and related method and imaging arrangement (IAR). The system (IPS) comprises an input interface (IN) for receiving i) a 3D input image volume (V) previously reconstructed from projection images (π) of an imaged object (BR) acquired along different projection directions and ii) a specification of an image structure in the input volume (V). A model former (MF) of the system (IPS) is configured to form, based on said specification, a 3D model (m) for said structure in the input 3D image volume. A volume adaptor (VA) of the system (IPS) is configured to adapt, based on said 3D model (m), the input image volume to so form a 3D output image volume (V′).

Abstract: The present invention relates medical imaging, more particularly to the display of medical images acquired in a tomosynthesis process. Processed 3D volume data representing a target acquired from scanning may be viewed from a set of forward projection directions, in which one or more forward projections through the processed 3D volume data is oblique relative to a central acquisition direction of the scanning process. The first set of forward projections is then displayed as a set of synthetic mammograms. Therefore, a medical practitioner can more easily identify abnormalities within a target volume, because the relative displacement of abnormalities at different depths in the target volume will change at different rates dependent on the viewing angle as the viewing position is moved around the target.

In particular, the image can be a two-dimensional projection image but also a three-dimensional volume of the object reconstructed from a tomosynthesis acquisition. An X-ray detector moving mechanism (18) is adapted for moving the X-ray detector (8) at least between a first X-ray detector position and a second X-ray detector position during operation of the X-ray system. An X-ray source (4), a collimator (22) and the X-ray detector (8) of the X-ray system (2) are adapted for acquiring a plurality of partial X-ray images through the adjacent detector tiles while irradiating the object with X-ray beams from a plurality of tomographic angles a. The processing unit is adapted for generating a two-dimension image of the object and/or for reconstructing a three-dimensional volume of the object from the acquired partial images.
