摘要: Whereas the CT image can be acquired in a single revolution, the CSCT image acquisition may require several revolutions. According to an exemplary embodiment of the present invention, a CT/CSCT apparatus may be provided which uses CT data acquired during the first revolution to optimize acquisition parameters for the subsequent revolutions. Furthermore, projection data acquired with a pre-scanner may also be used for determining current modulation or setting an optimum voltage for the subsequent CSCT scan.

摘要: For the display of images, notably X-ray images, the complete image of full resolution, usually consisting of a group of images, may be substantially larger than the size that can be reproduced on a display screen. In accordance with the invention, the overall group of images is displayed on the display screen as an auxiliary image in a strongly reduced scale, the size of the auxiliary image being dependent on the group of images. Via a frame which is reproduced in the auxiliary image and whose dimensions and position can be varied, a part of the group of images, i.e. one image or separate neighboring images, is selected and displayed on the overall display screen. When the frame is shifted in the auxiliary image, the part of the overall group of images which is displayed on the display screen is also automatically shifted. The images reproduced in the auxiliary image can be shifted and modified, for example rotated or enlarged or reduced, and any modification of an image situated within the frame is reproduced directly on the overall display screen. The overall view of the entire group of images is thus always preserved.
