Hi everyone,

I would like to do a time-reverse simulation. Indeed I have a point targeted by multiple SEFT that are going through different part of the skull. I would like to calculate the phase delay to be able to be at the focused point with all my transducers at the same time.

To do so I tried to do it manually by adding a source at the focus point and receptors (that are the transducers). It kind of work but then it is a real struggle to calculate precisely the phase. I did that following the instruction in the paper from Kyriakou et al. : *Full-wave acoustic and thermal modeling of transcranial ultrasound propagation and investigation of skull-induced aberration correction techniques: a feasability study.*

Is there any other easier solution to calculate this delay?

Thanks
