    摘要: A detector (2) for a positron emission tomography (PET)-scanning device is provided, the detector (2) including an opening (28) sized to accommodate the head of a human patient (P) and a plurality of sensor modules (22), which serve to detect emitted PET-radiation from the human patient (P) and which are arranged in the form of a regular polygon having a plurality of corners (24a, 24b, 24c). The detector further has an inner surface (23), which is arranged radially inside of the sensor modules (22), in order to circumferentially delimit the opening (28). The sensor modules (22) are arranged such that one of the corners is a nose corner (24a) which is adapted to accommodate the patient's nose (N) in the intended normal use of the detector (2). The inner surface (23) reflects the shape of the polygon at least in the region of the nose corner (24a).

    摘要: Various examples are provided related to predicting perfusion images from non-contrast scans. In one example, a method for predicting perfusion images includes generating perfusion maps of an organ of a subject from non-contrast computed tomography (NCCT) slices of the organ; processing the perfusion maps based upon weights determined by a Physicians-in-the-Loop (PILO) module; and generating synthetic computed tomography perfusion (CTP) maps from the processed perfusion maps, the synthetic CTP maps generated by deep learning-based multimodal image translation. In another example, a system includes at least one computing device that can generate prefusion maps of an organ from NCCT slices; process the perfusion maps based upon weights determined by a PILO module; and generate synthetic CTP maps from the processed perfusion maps using deep learning-based multimodal image translation. The CTP maps can be rendered for display to a user.

    摘要: An X-ray detection unit includes an X-ray detector that receives and detects the X-ray beam transmitted through the head. The support supports the X-ray generation unit and the X-ray detection unit. A drive mechanism moves the support such that the X-ray generation unit and the X-ray detection unit turn about an axis extending in a direction parallel to an apparatus vertical direction and around the head. An X-ray generation source moving unit moves the X-ray generation source in the apparatus vertical direction. The X-ray imaging apparatus increases a spread in the apparatus vertical direction of the X-ray beam when the X-ray generation source is located on an apparatus upper side, and decreases a spread in the apparatus vertical direction of the X-ray beam when the X-ray generation source is located on an apparatus lower side.
