摘要： Systems and methods for data acquisition in computed tomography (CT) applications are provided. The systems and methods are particularly adapted for scanning and acquiring/processing data in connection with high-power cone-beam CT applications. The electron beam is moved/scanned along the anode surface to multiple focal positions. Data acquisition for a full projection at one focus position and one view angle is achieved by activating each focus position multiple times during the data acquisition for one angle of the gantry. The detector array and associated data processing system are adapted to rapidly switch between the different focus positions during the acquisitions for one view angle and to collect all data belonging to the same projection into the same data set. Adaptive electron optics are utilized to move/scan the electron beam along the anode surface to the various focus positions. Alternatively, a plurality of cathodes may be provided for respective focus positions and the system may support fast switching therebetween to achieve desirably short spot times. The disclosed CT system permits greater power densities without risk of heat damage to the anode and effectively increases the track velocity of the electron beam on the anode surface. The CT system and associated data acquisition methods have particular utility in CT applications requiring increased time resolution and/or spatial resolution, e.g., cardiac CT applications.

摘要： The invention relates to an apparatus and a method for the processing of reconstructed 3D images (I) in C-arm based volume imaging which often exhibit spatially slowly varying inhomogeneities caused by inconsistent projection data. To correct the images (I), a retrospective homogenization procedure is proposed. The image (I) is segmented (11, 12) into principal classes like bone, tissue and air based on their gray values. Only the tissue-regions (M) are then used as support in order to fit (14) a spatially slowly varying 2D baseline (B) representing the smooth shape of cupping or other inhomogeneities. Finally the inverse of the estimated 2D baseline is subtracted from the original slice (I) to correct for the inhomogeneities.

摘要： A method is provided for detecting a movement of a body between acquisition times of at least two acquisition data sets, wherein, for virtual sectional planes of the body, a first intermediate function value of attenuation values of all the body elements lying in the sectional plane is determined based on a first acquisition data set, and a second intermediate function value of the attenuation values is determined based on a second acquisition data set. For each sectional plane, a difference value is determined from the intermediate function values. A total error value for the two acquisition data sets is calculated by combining the difference values of all the sectional planes. The virtual sectional planes have a common line of intersection, and for the particular acquisition time, the difference between pairs of the sectional lines is at least one pixel.
