摘要： The invention relates to a method for optimizing the throughput when processing images from X-ray computer tomographies (CT). The proposed method for handling or processing image data from individual images or consecutive images is based on a substantially punctiform radiation source (70), by which an object (1) to be captured or reconstructed is depicted on a flat detector (80) readable as a screen. A plurality of processing strips (T1, T2) of the image are read at the detector (80), wherein each strip (T1, T2) takes up an image portion. The image portion is associated by a respectively associated volume layer (V1, V2) of the object (10) with respect to the radiation path of the radiation source (70). A respective image data portion in a respective processing strip (T2) is fed to a processing unit (E2). Each volume layer (V1,V2 , V6) of the object can hereby be reconstructed; a respective volume layer is reconstructed by one - of a plurality of - processing units (E1,E2 ,E6).

The following steps are provided: a first initialisation, whereby a first orientation of the sample (10) is merely coarsely determined with a first rapid recording, a recording in which the position of the sample (10) is more accurately determined, in particular by feature point pairs, a movement, whereby after a successful recording of several projections, the position of the sample (10,11) is calculated for at least one further projection, a simulation, whereby a virtual CT is carried out using the results from the previous step, providing input data for an ensuing correction method for the CT reconstruction, carrying out a correction, whereby during data recording (70) by the detector, parameters are determined from the correction data and a correction is then carried out (73a,73b) and the reconstruction, whereby in the period at the end of the recording process corrected projection data (11*) as a data recording (70) are provided as an improved CT reconstruction (74,75).

摘要： The invention is based on the fact that a representation of an object can be improved by means of an irradiation, in view of an ensuing reconstruction of the object based on the representation. In order to achieve this, simulated data corresponding to a simulated irradiation of the object is used, before a reconstruction, as prior information for measuring an irradiation of the object and/or for producing the representation from a measured irradiation. The invention relates to a method for representing an object (10) by means of an irradiation. Said method involves preparing simulated data corresponding to a simulated irradiation of the object (10), in a memory (20) for example; using the simulated data for measuring an irradiation of the object (10) by means of a control mechanism (24), in a CT scanner (12) for example, in order to obtain the irradiation of the object; and/or using the simulated data for producing the representation from a measured irradiation by means of a data preparation device (26).

摘要： The invention is based on the knowledge that a representation of an object can be improved via a transmission with regard to a subsequent reconstruction of the object based on the representation, by using simulated data, which correspond to a simulated transmission of the object already prior to a reconstruction as advance information for measuring a transmission of the object and/or for generating the representation from a measured transmission. An inventive method for the representation of an object via a transmission comprises providing simulated data, which correspond to a simulated transmission of the object, for example in a memory, and using the simulated data for measuring a transmission of the object, for example in a computertomograph, to obtain the transmission of the object, by a control and/or using the simulated data for generating the representation from a measured transmission by a data preparation means.

摘要： The invention relates to a device for creating a correction characteristic curve for reducing artefacts in tomography. Said device comprises a unit (10 ) for preparing projection data of the object, said projection data comprising irradiation values for the object, a device (12) for calculating a representation of the object from the projection data in order to obtain two or three-dimensional representation data for the object, a device (14A) for determining a measurement for the irradiation length of the object using the representation data, a device (14B) for determining an irradiation value, which is allocated to the measurement that has been determined for the irradiation length and a device (16) for creating the correction characteristic curve from several measurements that have been determined for irradiation lengths and their allocated irradiation values. According to the invention, the correction characteristic curve that has been determined is used to carry out a preliminary correction of the projection data, in order to iteratively determine the correction characteristic curve using the previous ly corrected irradiation values. Said concept for creating a correction characteristic curve does not require any reference object measurements or other information concerning the nature ofthe irradiation source, the object etc.
