From the OpenwaterHealth/opw_neuromod_sw README: https://github.com/OpenwaterHealth/opw_neuromod_sw https://github.com/OpenwaterHealth/opw_neuromod_sw : > open-LIFU uses an array to precisely steer the ultrasound focus to the target location, while its wearable small size allows transmission through the forehead into a precise spot location in the brain even while the patient is moving. Does it use one beam of the array to waveguide another beam? For imaging or for treatment? From "A simple technique to overcome self-focusing, filamentation, supercontinuum generation, aberrations, depth dependence and waveguide interface roughness using fs laser processing" (2017) https://www.nature.com/articles/s41598-017-00589-8 https://www.nature.com/articles/s41598-017-00589-8 https://scholar.google.com/scholar?start=10&hl=en&as_sdt=5,47&sciodt=0,47&cites=11686473802297914479&scipsc= https://scholar.google.com/scholar?start=10&hl=en&as_sdt=5,4... : > We show that all these effects can be significantly reduced if not eliminated using two coherent, ultrafast laser-beams through a single lens - which we call the Dual-Beam technique. Simulations and experimental measurements at the focus are used to understand how the Dual-Beam technique can mitigate these problems. The high peak laser intensity is only formed at the aberration-free tightly localised focal spot, simultaneously, suppressing unwanted nonlinear side effects for any intensity or processing depth. Therefore, we believe this simple and innovative technique makes the fs laser capable of much more at even higher intensities than previously possible, allowing applications in multi-photon processing, bio-medical imaging, laser surgery of cells, tissue and in ophthalmology, along with laser writing of waveguides.
