Embodiment Construction

[0084] figure 1 The problem on which the invention is based is clarified. Two objects, namely a glass and a bottle, which should be considered to represent structures in the object, are at different positions b1 and b2, i.e. with respect to the distance from the two illumination points P1, P2 extending through the midpoints of these objects respectively. The different positions b1 and b2 with respect to the plane R are reconstructed. These points P1 and P2 can also be regarded as shooting points, but the present invention belongs to the field of X-ray imaging, which better presents X-ray photos for a better intuitive image. In the case of medical photography, the B value would correspond to the TOD value. The dashed lines drawn at distances bl, b2 and bmax correspond to possible reconstruction planes R.

[0085] A first single image E1 illuminated by point P1 shows part of the bottle and glass, a second single image E2 illuminated by P2 shows another part of the bottle and ...

Abstract

The present invention relates to an apparatus and method for fine-tuning a reconstruction plane of a digitally composited image. The present invention relates to a method and a device for fine-tuning the reconstruction plane of a digital composite image formed from individual images of a digital imaging diagnostic system. The device comprises: an interface for providing the individual images of the object, wherein the individual images have overlapping regions with each other; a distance regulator with which the distance A of the individual images can be changed; a calculation unit for calculating A current composite image composed of the individual images, wherein the individual images are each moved by a distance A from each other; and a display unit for displaying the current composite image composed of the individual images. The invention also includes an image analysis system and / or a digital image diagnosis system comprising such a device.

Description

technical field [0001] The invention relates to a digital composition for the composition of individual images of a digital diagnostic imaging system, in particular for the production of long film cassette photographs in the stepping acquisition mode (Stepping Akquisitions-Modus) A device and method for fine-tuning a reconstruction plane of an image. Background technique [0002] In the case of digital radiography, in particular when imaging large body regions, it occurs that the reception detector limits the size of the region that can be visualized anatomically. For example, the representation of the spine in some cases exceeds the size of image receivers available today by many times. In this case, multiple photos must be made for this purpose in spatial and temporal sequence and then recombined into a unique image (referred to herein as a "composite image"). For example, in the case of the so-called “stepping” method, the x-ray source and the detector are moved vertica...
