Main Focus

The main focus of my research is the entire workflow of parallel transmission (pTx) at ultrahigh field MRI. This starts with the evaluation and comparison of different designs for radio frequency (RF) transmit array coils. While performance is an important aspect, I also work on RF safety evaluation for in-house developed hardware.
Knowledge of the magnetic field generated by each RF element, the so-called B1+ field, is crucial for the efficient use of a pTx setup. I have investigated and compared different methods to efficiently measure the B1+ fields of multi-element coils.
More recently, I have been working on pTx pulse design and how it can benefit from modern algorithms and the powerful computing hardware that has recently become available. While state-of-the-art pTx applications often optimize RF and gradient waveforms separately, I developed a toolbox called FastPtx that uses PyTorch to optimize RF and gradient waveforms simultaneously, taking advantage of PyTorch's autodifferentiation capabilities to reduce the time required for optimization.
