This study presents a new flatness-based control scheme for the quantum series–parallel LCC-type resonant converter with output voltage doubler for high-voltage pulse applications, like medical X-ray imaging. Based on a previously derived continuou

In this paper, an imaging system is considered, which is part of an activity to test the feasibility of clinical (whole-body) magnetic particle imaging (MPI). Recent studies on nerve stimulation in humans indicate that drive field amplitudes have to

A clinical MPI demonstrator system is being built [1] that will enable fast 3D imaging with 3D drive field excitation and rapid 3D focus fields. To date, all components have been realized only once, i.e., a 1D drive field coil (x direction), a 1D fas

New load and current observers for the boost converter are proposed, one of which uses voltage measurement only. A flatness based trajectory planning algorithm is suggested. It exploits the parameterization of the trajectories in the energy in order

The Digital Chain is realized as an adaptive finite impulse response filter (FIR). FIR filters with the order of N consist of (N-1) time delay elements, adder and filter coefficients w(n). Based on the measured harmonics in the voltage of ZLoad the f

When shifting the FOV during imaging, artifacts arise when the shift per volume encoding time is larger than the resolution. Up to shift velocities of about 1 m/s, these can be removed by compensating the system function for the rapid translation. Fa

In order to identify suitable operating conditions for future clinical Magnetic Particle Imaging, peripheral nerve stimulation (PNS) and specific absorption rate (SAR) experiments have been performed by exposing volunteers to sinusoidally time-varyin
