Abstract
An assembly for imaging and/or treating brain tissue, having at least one acoustic window which comprises a plate that is transparent to ultrasonic waves, and at least one positioning marker which facilitates positioning of a probe for generating ultrasonic waves so as to be aligned with said acoustic window.
Claims14
An assembly for imaging and/or treating a brain tissue comprising:
- at least one acoustic window configured to be implanted at an opening arranged into the cranium of a patient, and configured to be covered with the skin of the patient's skull once implanted;
- an ultrasonic wave generation probe intended to be positioned in line with the acoustic window,
- wherein the acoustic window comprises:
- a plate transparent to ultrasonic waves, and
- a plurality of positioning marks configured to be locatable through the skin of the patient in order to facilitate the positioning of the probe in line with said acoustic window,
- each of the plurality of positioning marks being configured to return a reflection time detectable by the ultrasonic wave generation probe;
- and
- a processing unit communicatively connected to the ultrasonic wave generation probe, the processing unit being configured to:
- determine which of the plurality of positioning marks has been detected based on the reflection time, and
- display an instruction to displace the ultrasonic wave generation probe in a specified direction based on which of the plurality of positioning marks has been detected.

An assembly for imaging or treating a brain tissue, the assembly comprising:
- at least one acoustic window configured to be implanted at an opening arranged into the cranium of a patient, and configured to be covered with the skin of the patient's skull once implanted;
- an ultrasonic wave generation probe intended to be positioned in line with the acoustic window,
- wherein the acoustic window comprises a plate transparent to ultrasonic waves, and wherein the plate comprises:
- a first plurality of positioning marks detectable by ultrasonography, and
- a second plurality of positioning marks detectable by magnetic resonance imaging (MRI),
- each of the first plurality of positioning marks being configured to return a reflection time detectable by the ultrasonic wave generation probe;
- and
- a processing unit communicatively connected to the ultrasonic wave generation probe, the processing unit being configured to:
- determine which of the first plurality of positioning marks has been detected based on the reflection time, and
- display an instruction to displace the ultrasonic wave generation probe in a specified direction based on which of the first plurality of positioning marks has been detected.
7 more elements
A method for imaging or treating a brain tissue of a patient, the method comprising:
- detecting, by operating an ultrasound device in a first mode of operation, a first positioning mark of a plurality of positioning marks integrated in an acoustic window implanted at an opening in the cranium of the patient, wherein the acoustic window is covered with the skin of the patient's skull, wherein the acoustic window comprises a plate transparent to ultrasonic waves, wherein the plurality of positioning marks are detectable by ultrasonography, and wherein each of the positioning marks comprises a blind hole having a different depth from any other positioning mark of the plurality of positioning marks;
- determining, based on a reflection time corresponding to the positioning mark, which positioning mark of the plurality of positioning marks has been detected;
- displaying, based on the determining, an instruction to displace the ultrasound device in a specified direction;
- after detecting, by the ultrasound device, all positioning marks of the plurality of positioning marks, sending an instruction to maintain the ultrasound device in a stationary position;
- and
- applying, by the ultrasound device operating in a second mode of operation, ultrasonic waves to the patient, wherein the second mode of operation corresponds to an imaging mode or a treating mode.
