    Abstract: A reconstruction apparatus (9) reconstructs a PET image. A first detector (3) generates first detection events and detection times assigned to the first detection events and a second detector (6) generates second detection events and detection times assigned to the second detection events. A timing window determination unit (11) provides a first-second timing window by providing a first-second upper threshold based on the position of the second detector relative to the first detector and a detection event pairs generation unit (12) generates first-second detection event pairs based on the provided first-second timing window. The first-second detection event pairs are used for reconstructing the PET image. The first-second timing window depends on the position of the second detector leads to an improved generation of first-second detection event pairs, which in turn can lead to an improved PET image.

    Abstract: Described herein is an approach to identify a presence (or absence) of a tissue disease based on a quantification of a roughness of a surface of the tissue represented in imaging data. The approach includes an image data processor (120) with a surface roughness quantifier (206) that generates a metric that quantifies a roughness of a surface of a tissue of interest in 3D image data based on a surface model adapted to the tissue of interest in the 3D image data and a decision component (208) that generates a value signal indicating a presence or an absence of disease in the tissue of interest based on the metric.

    Abstract: The present invention relates to an apparatus (10) for correcting computer tomography (“CT”) X-ray data acquired at high relative pitch, the apparatus comprising: an input unit (20); a processing unit (30); and an output unit (40). The input unit is configured to provide the processing unit with CT X-ray data of a body part of a person acquired at high relative pitch. The processing unit is configured to determine CT slice reconstruction data of the body part of the person with no or reduced high relative pitch operation reconstruction artefacts using a machine learning algorithm. The machine learning algorithm was trained on the basis of CT slice reconstruction data, and wherein the CT slice reconstruction data comprised first CT slice reconstruction data with high relative pitch reconstruction artefacts and comprised second CT slice reconstruction data with less, less severe, or no high relative pitch reconstruction artefacts. The output unit is configured to output the CT slice reconstruction data of the body part of the person.

    Abstract: A method and apparatus for analyzing diagnostic image data are provided in which a plurality of acquisition images of a vessel of interest having been acquired with a pre-defined acquisition method is received at a trained classifying device and classified, by the classifying device, to extract at least one quantitative feature of the vessel of interest from at least one acquisition image of the plurality of acquisition images. The at least one quantitative feature is then output associated with the at least one acquisition image while the acquisition of the diagnostic image data is still in progress and one or more adjustable image acquisition settings are adjusted based on the at least one quantitative feature to optimize the acquisition of the diagnostic image data.

    Abstract: The present invention relates to the use of dark field X-ray images in an ablation treatment of a tumour. By acquiring dark field X-ray images displaying the region of interest targeted in the ablation treatment, information can be derived which allows taking a decision on terminating the ablation treatment. A set of dark field X-ray images is received (101), which is acquired at different time instants and comprises the region of interest. Dark field X-ray images of the set are compared (102), for example by determining difference images between the individual images. If during that comparison a change in the dark field X-ray images is detected over time in the region of interest, then a signal is generated (103) indicating a change has occurred. That signal may indicate that healthy tissue is being affected instead of the tumour and that consequently the ablation treatment should be ended.
