Abstract: A tomogram of a body is provided. Projection-image data obtained by a radiation-based projection method is used for providing the tomogram. Initial voxel data are first specified for a plurality of voxels of the body. Synthetic projection-image data are generated based upon a projection rule modeling a course of the projection method. Projection-error data is determined by comparing the synthetic projection-image data with the real projection-image data. The projection-error data are imaged on the basis of a back-projection rule dependent on the projection rule so that voxel-error data are produced. Correction data is generated from the voxel-error data by a gradient-based optimizing algorithm, wherein corrected voxel data are generated using the correction data.

Abstract: A power supply regulator circuit uses a feedback loop to control current through a first output transistor from a power supply input to a regulated power supply output. The first output transistor is included in an integrated circuit. In order to avoid heating of the integrated circuit in excess of an acceptable level due to permanent supply of a high current through the first transistor, current through a second output transistor in parallel with the first transistor, but outside the integrated circuit is raised when it is detected that the current through the first output transistor exceeds a threshold level. The second output transistor outside the integrated circuit serves to take over supply of a part of the power supply current from first output transistor inside integrated circuit, when long term supply of that part from first output transistor would lead to undesirable heating of the integrated circuit. During a limited time interval a first transistor current above the threshold level is acceptable.
