Abstract: A two-channel magnetic resonance tomography system is provided with a regulation circuit for an amplification system in order to be able to take into account different load situations of the MRI system in a flexible and efficient manner. It is thus possible to improve the MRI measurements greatly if the MRI system is set to the respective load situation beforehand by an idle state measurement. The adaptation may optionally also be carried out during the MRI measurement. Therefore, a multiplicity of completely different load situations may be taken into account in an optimized manner by the regulation circuit.

Abstract: A magnetically guided endoscopy capsule is separated from the surface of water with the aim of immersing the capsule completely in water, using the least possible magnetic force. A brief force curve (F_mag(t)) is thereby automatically generated on the capsule by a solenoid system, by one or more force pulses. Assuming that the capsule floats on the water surface at the start of the force curve, a force curve is applied generating an odd number of force pulses having a step profile. Each odd force pulse brings about at least a partial immersion of the endoscopy capsule in the liquid, and each even force pulse bring about at least a partial emersion of the endoscopy capsule out of the liquid.
