摘要： There is described a method for a periodic and three-dimensional representation of a periodically variable structure. A number of rotation images is generated for this purpose. The required rotations relating to the same event of the periodic process are started at intervals offset by a defined angle. From the rotation images, new image series are assembled with which three-dimensional representations relating to different phase ranges of the period are reconstructed.

A first image data set is supplied comprising at least two images of the perfused region recorded at different times before and after an injection of contrast agent into a first artery supplying the region. A second image data set is supplied comprising at least two images of the perfused region recorded at different times before and after an injection of contrast agent into a second artery supplying the region. A first functional data set is generated by pixel-based calculation of at least one perfusion parameter from the first image data set. A second functional data set is generated by pixel-based calculation of at least one perfusion parameter from the second image data set.

摘要： The invention relates to a method for three-dimensional representation of a moving structure by a tomographical method. Projection images are recorded by an image recording unit during a rotational run from recording angles between a start angle and an end angle, with a three-dimensional image data reconstructed from the projection images, with a first perfusion measurement with a first contrast agent injection and a first rotational run and with a further perfusion measurement with a further contrast agent injection and a further rotational run, which is started after the preceding perfusion measurement has concluded, with the start time and/or the start angle of the additional rotational run deviating from one another in respect of the time of the contrast agent injection. The method enables a functional three-dimensional time-resolved imaging of perfusion processes with the aid of flexible C-arm x-ray devices, which allow a functional imaging in an interventional environment.

摘要： The invention relates to a method for the production of angiography recordings. First, a mask image is recorded with a first modality. A contrast medium is injected after the first recording. A control image is recorded with a second modality after the injection of the contrast medium. A spreading of the contrast medium is determined based on the images and the control of subsequent recordings is analyzed. A recording criterion is checked to determine whether the recording criterion has been achieved. If it has not been achieved, the control image is repeatedly recorded for repeatedly determining the spreading of the contrast medium. If it has been achieved, a contrast image is recorded with the first modality and the mask image and the contrast image are processed and analyzed.

摘要： The invention relates to a method and a device for the separate three-dimensional representation of arteries and/or veins in a vascular system of the body by means of a C-arm biplanar system having two C-arms, which can each record a sequence of x-ray images from different projection angles during a mask or filler pass. With the filler pass, both C-arms record x-ray images, so that the x-ray images of the filler pass can be combined to form a first data record, which contains x-ray images from the arterial phase of the vascular contrasting and/or to form a second data record, which contains x-ray images from the venous phase of the vascular contrasting. This enables the arterial and venous phases to be reconstructed separately.
