摘要： A system and method for producing three-dimensional representations of an object. A first series of projected images of the selected object is recorded in a first projection plane and a second series of projected images of the selected object is recorded in a second projection plane. The first and the second series of projected images are rendered at a common magnification. The first set of projected images is then integrated into a first three-dimensional volume and the second set of projected images is integrated into a second three-dimensional volume. The three-dimensional representation of the object is then produced by combining one projected image from the first set of projected images with one projected image from the second set of projected images. Alternatively, the three-dimensional representation is produced by merging the first three-dimensional volume with the second three-dimensional volume.

摘要： A control device (4) for a medical imaging system drives a signal source (1) and a detector (2) so that the detector (2) registers raw data of an object (5). Said device accepts the registered raw data and conveys send data corresponding to said registered raw data via a computer-to-computer link (10) to a computing device (11) not assigned to the medical imaging system. Said device determines an end data record by means of the send data and conveys it to the control device (4) via the computer-to-computer link (10). At least one end image is defined by the end data record. The control device (4) feeds out the end image to a user (15) of the medical imaging system via a viewing device (16).

摘要： A system and method for ascertaining the identity of an object within an enclosed article. The system includes an acquisition subsystem, a reconstruction subsystem, a computer-aided detection (CAD) subsystem, and an alarm resolution subsystem. The acquisition subsystem communicates view data to the reconstruction subsystem, which reconstructs it into image data and communicates it to the CAD subsystem. The CAD subsystem analyzes the image data to ascertain whether it contains any area of interest. A feedback loop between the reconstruction and CAD subsystems allows for continued, more extensive analysis of the object. Other information, such as risk variables or trace chemical detection information may be communicated to the CAD subsystem to dynamically adjust the computational load of the analysis.

摘要： To perform cone beam reconstruction by using projection data correctly corresponding to X-ray beam having passed through each pixel in the reconstruction area, data D1 is obtained which is plane projected to a plane based on projection data D0. Then, plane projection data D1 to the projection plane pp is projected to the reconstruction area in the direction of X-ray transmission to obtain back projection pixel data D2. Thereafter, back projection pixel data D2 will be added for each corresponding pixel for all views to obtain back projection data D3. The present invention provides reconstruction by device of projection data correctly corresponding to the X-ray beam having passed through the reconstruction area. Through the plane projection to a plane the operation will become simplified and faster.

摘要： A method and apparatus are disclosed in an EBT scanner for generating an image from a data set collected from a subject beginning at an arbitrary time within a scanning time interval. A sequence of temporally separated, unfolded parallel view sinograms are generated corresponding to scans through the subject during the scanning time interval. Data from each of the sinograms are folded into each other such that loss of information and image artifacts, caused by temporal separation between temporally adjacent sinograms, are greatly reduced. An image is generated from a subset of data taken from the folded sinograms wherein the subset of data begins at an arbitrary time within the scanning time interval.
