摘要： The invention relates to a method for checking tooth positions, wherein an initial three-dimensional volume exposure (1) of teeth (2, 3, 4) to be checked is implemented, wherein the position and orientation of the teeth (2, 3, 4) to be checked are determined based on the initial volume exposure (1); wherein the teeth to be checked are natural teeth (2, 3, 4) comprised of tooth stumps (6, 7, 8) and tooth roots (9, 10, 11) and/or are artificial teeth comprised of artificial tooth stumps and implants; wherein the positional relationship and orientation of the tooth stumps (6, 7, 8) relative to the tooth roots (9, 10, 11) and/or to the implants are determined in particular. For checking, a first optical surface monitoring exposure (25) of the teeth (2, 3, 4) is implemented, wherein using the positional relationship thus determined the position and orientation of the tooth roots (9, 10, 11) and/or of the implants relative to one another and/or relative to a jawbone (5) are determined based on the position of the surfaces (13, 14, 15) of the tooth stumps (6, 7, 8) from the optical surface monitoring exposure (25).

摘要： The invention relates to a method for capturing a three-dimensional x-ray image (1) of an object (2) by means of an x-ray system (3) comprising an x-ray source (4), an x-ray detector (5) and a shutter matrix (7), the shutter matrix (7) having a plurality of shutter elements (18), the x-ray absorption properties of which are controllable. In the first method step, at least one region (21) to be captured of the object (2) is defined, wherein settings are planned for the individual shutter elements (18) of the shutter matrix (7) for different rotary positions (14, 15, 16, 17), taking into account the defined area (21) to be captured. Then, a plurality of two-dimensional x-ray images is captured from the planned rotary positions (14, 15, 16, 17) during at least one partial rotation (9) using the planned settings of the shutter elements (18), wherein the overall three-dimensional x-ray image (1) of the area (21) to be captured is generated from the individual two-dimensional x-ray images.
