摘要： Digital subtraction angiography is used to improve the contrast of images of patient vasculature. A non-contrast image is recorded with no contrast medium injected into the patient, and then a succession of contrast images is captured after the injection of a contrast medium. The non-contrast image is successively registered to the contrast images, and then subtracted. This removes background structures, but leaves the vasculature untouched, making blood vessels easier to see. Artefacts can remain when different motion layers are present in the X-ray image (for example, the spine and the lungs). This application discusses a technique to prevent artefacts occurring when different motion layers are present in an X-ray frame or sequence.

摘要： An imaging system (10) and related method, where a marker detection system (MDS) detects one or more markers (MK) spatially arranged in association with an area (A). If the marker detection system (MDS) detects that the area (A) is within a field-of-view (FoV) of the imaging system (10) or is at least within a predefined distance thereof, a control signal is issued in respect of said area (A) to an image acquisition system (ACS) of the imaging system (10). The area (A) may be one of a hand (32) of a human operator or a part of a patient (12) to be imaged.

摘要： Method and related system (IPS) for visualizing in particular a volume of a substance during its deposition at a region of interest (ROI). A difference image is formed from a projection image and a mask image. The difference image is then analyzed to derive more accurate motion information about a motion or shape of the substance. The method or system (IPS) is capable of operating in an iterative manner. The proposed system and method can be used for processing fluoroscopic X-ray frame acquired by an imaging arrangement (100) during an embolization procedure.
