Multi-sensor brain detecting apparatus
The invention concerns a multi-sensor brain detecting apparatus, the detecting apparatus being adapted to obtain two different physical values of a brain of a subject, the detecting apparatus comprising: a set of sensors comprising an ultrasound transducer adapted to produce ultrasound waves, a frame with a position with relation to the brain known with a stereotaxic precision, the frame being adapted to hold a sensor that can be positioned at a specific location by a user of the detecting apparatus without using a tool.
1. A multi-sensor brain detecting apparatus, the detecting apparatus being adapted to obtain at least two different physical values of a brain of a subject, the detecting apparatus comprising:
a frame configured as attachable to the head of the subject at a fixed position with relation to the brain with stereotaxic precision, the frame comprising a perimeter region surrounding a plurality of compartments, each compartment positioned at a respective location relative to the perimeter region, among a plurality of locations; and
a set of sensors, including at least an ultrasound sensor adapted to produce ultrasound waves, at least one sensor of the set of sensors being configured as removably insertable into any of the compartments and correspondingly selectively positionable at any of the locations, by a user of the detecting apparatus without using a tool.
2. The multi-sensor brain detecting apparatus according to claim 1 , wherein the position of the flame with relation to the brain is known by using an anatomical frame.
3. The multi-sensor brain detecting apparatus according to claim 1 , wherein the detecting apparatus further comprises a specific sensor adapted to determine the position of the frame.
4. The multi-sensor brain detecting apparatus according to claim 1 , wherein two sensors of the set of sensors are adapted to measure different physical quantities.
5. The multi-sensor brain detecting apparatus according to claim 1 , wherein the frame has a polygonal shape delimited by sides, each side having length inferior or equal to 10 centimeters.
6. The multi-sensor brain detecting apparatus according to claim 1 , wherein the set of sensors comprises three sensors, one sensor being an ultrasound transducer, one sensor being an accelerometer and one sensor being adapted to measure electrical signals.
7. The multi-sensor brain detecting apparatus according to claim 1 , wherein one sensor of the set of sensors comprises a printed multielectrode electroencephalography foil.
8. The multi-sensor brain detecting apparatus according to claim 1 , wherein the set of sensors includes a sensor that comprises one or multiple implantable electroencephalography electrodes.
9. The multi-sensor brain detecting apparatus according to claim 1 , wherein each sensor has a sensing portion and a mechanical portion adapted to maintain the sensing portion in position and wherein, for each sensor, the mechanical portion of one sensor has a shape which is complementary to the shape of the mechanical portion(s) of the other sensor(s).
10. The multi-sensor brain detecting apparatus according to claim 1 , wherein the detecting apparatus further comprises an interface adapted to fix the detecting apparatus to the subject's head in order that the detecting apparatus moves with the subject's head without changing the position of the frame with relation to the brain.
