Acoustic window for imaging and/or treatment of brain tissue

A surgical implant set comprising a package, in particular an individual package, wherein the implant set comprises a window contained in the package, and instructions for use of the window as an acoustic window configured to be implanted at an opening in a patient's skull, said acoustic window cooperating with an external ultrasound probe for the emission of ultrasound waves through the acoustic window, wherein the acoustic window comprises a plate including a plurality of through-holes, the distance P between two adjacent through-holes being less than five times the wavelength of the ultrasound waves emitted by the external ultrasound probe.

A system for imaging and/or treating brain tissue, the system including an ultrasound-wave-generating probe, wherein the system further comprises an acoustic window configured to be implanted at an opening in a patient's skull, said acoustic window cooperating with an external ultrasound probe for the emission of ultrasound waves through the acoustic window, wherein the acoustic window comprises a plate including a plurality of through-holes, the distance P between two adjacent through-holes being less than five times the wavelength of the ultrasound waves emitted by the external ultrasound probe.
