摘要： The present invention is related to a method for deriving shape information of a person's dentition. The method comprises the steps of
- obtaining a first data set by taking a 3D scan of the person's dentition with markers fixed in the person's intra-oral cavity,
- digitizing an impression of the person's dentition with the markers fixed, yielding a second data set,
- fusing the first and the second data set based on corresponding pairs of the markers,
- deriving the shape information from the fused first and second data sets.

摘要： The invention relates to a method for producing 3D tomographic images of an object, whereby a radiation source (1), especially an X-ray source, is moved in relation to the object in a plane of motion (6) about a rotating center. The radiation source (1) emits radiation in a radiation cone (2) whose center beam (3) impinges the object. A correspondingly entrained detector (4) is arranged in said center beam, on the side of the object facing away from the radiation source, and is impinged upon by the radiation attenuated in its intensity by the object. The movement is carried out in such a manner that the center beam (3) is tilted by an angle in relation to the plane of motion (6).

摘要： The image display method comprises a three-dimensional image creating step that creates a three-dimensional image based on volume data; a cutting plane setting step that sets a cutting plane that cuts the three-dimensional image at an arbitrary position; and a positional relationship display image creating step that creates a positional relationship display image representing the mutual positional relationship between the three-dimensional image and the cutting plane, in which the opacity of the cutting plane in the positional relationship display image is adjusted so that a portion of the three-dimensional image that is hidden by the cutting plane is visually recognizable through the cutting plane in the positional relationship display image.

摘要： The present invention relates to an x-ray image recording system for recording x-ray projection images of alignment information for recorded x-ray projection images, comprising an x-ray tube 10 and an x-ray image detector 9 being arranged in the optical path of the x-ray tube for recording x-ray projection images of an object O that can be disposed and/or that is disposed between the x-ray tube and the x-ray detector in an imaging region B in a locally fixed manner, wherein the x-ray tube and the x-ray detector are disposed in a locally fixed manner relative to each other, and can be moved about the imaging region, at least in sections, a position sensor 2 being disposed relative to the x-ray tube 10 and the x-ray detector in a locally fixed manner, by means of said sensor the current alignment of the x-ray tube and the x-ray detector can be determined relative to a predefined reference direction R at the moment of recording of an x-ray projection image, and a storage unit 1a for storing recorded x-ray projection images together with the respective current alignment of the x-ray tube and the x-ray detector. The invention comprises a computer 1b being connected to the storage unit 1a for the purpose of data exchange, by means of said computer the position data of the x-ray projection image that are necessary for the calculation of the layered images of the reconstruction can be calculated from the stored, associated current alignment for the purpose of layered image reconstruction based on multiple recorded x-ray projection images for each recorded x-ray projection image utilized.

摘要： When generating projection images from three-dimensional image data, obtained by reconstructing multiple two-dimensional images, by changing the viewpoint and observing the generated projection images, facilitating the understanding of three-dimensional positional relationship. When an area of attention is specified in a first projection image and a second projection image is generated from a second viewpoint position and/or a second projection direction different from the viewpoint position and/or the projection direction of the first projection image, an area of a second projection image obtained by projecting a voxel in the three-dimensional data corresponding to the specified area of attention from the second viewpoint position and/or in the second projection direction is displayed in the second projection image.

摘要： when generating an intermediate image, which is an image in the middle of changing from one to the other of two pseudo three-dimensional images generated by ray casting a three-dimensional image under two different opacity level setting conditions, determining an opacity level setting condition by determining an opacity level to be allocated according to each pixel value such that a variation in the opacity level for a change in a changing phase of the intermediate image become smaller as the changing phase approaches closer to a pseudo three-dimensional image generated under either one of the two different opacity level setting conditions in which a smaller value is allocated as the opacity level to be allocated according to each pixel value, and generating an intermediate image which appears to change substantially linearly with a linear change in the changing phase by ray casting the three-dimensional image under the determined opacity level setting condition.
