摘要： A computer tomography apparatus has an anode in the form of a partial ring along which a focus is electronically moved to generate a scan beam from different directions, and a partial ring detector which generates a number of data sets from the attenuated radiation at the different directions, includes a computer wherein the data sets are weighted independently of the measured values so that image reconstruction can be undertaken with a standard computer tomography method, such as convolution and back-projection. The weighting is selected so that the boundaries of regions having constant values represent smooth curves in the sinogram. The image can thereby be reconstructed without complementary interpolation, which is normally required in computer tomography systems having a partial ring x-ray source and detector.

摘要： An x-ray tube for computer tomography (CT) has a cathode for generating an electron beam, a rotating anode having an incident area onto which the electron beam is incident in a focal spot, and a deflection system for deflecting the electron beam, dependent on an electrical deflection signal, in a deflection direction intersecting the circumferential direction of the rotating anode, such that the focal spot periodically moves from an initial position into a final position once during once per scanning position.

摘要： In a method for the calculation of a temperature T of a solid body of a liquid cooling medium, or the time t needed for a temperature change of the solid body or the liquid cooling medium, the differential equation dT/dt=b−cT is converted into a dimensionless differential equation. The function that solves the dimensionless differential equation is used to compile a matrix A(=aij), with which T and/or t can be easily calculated.
