The invention refers to an apparatus for monitoring a subject () during an imaging procedure, e.g. CT-imaging. The apparatus () comprises a monitoring image providing unit () providing a first monitoring image and a second monitoring image acquired at different support positions, a monitoring position providing unit () providing a first monitoring position of a region of interest in the first monitoring image, a support position providing unit () providing support position data of the support positions, a position map providing unit () providing a position map mapping calibration support positions to calibration monitoring positions, and a region of interest position determination unit () determining a position of the region of interest in the second monitoring image based on the first monitoring position, the support position data, and the position map. This allows to determine the position of the region of interest accurately and with low computational effort.

The present invention relates to a control circuit () for controlling a resonant power converter. It is described to generate () a modulation signal. A carrier signal is generates (), wherein the generation of the carrier signal comprises measuring at least one signal from the power converter. A switching signal is generated () that is useable to control a value of at least one magnitude of the resonant power converter based on the modulation signal and the carrier signal.
