A magnetoencephalogram (MEG) system is provided for use with a head. The MEG system includes a shell, and three three-axis gradiometers and a computing portion. Each three-axis gradiometer detects a magnetic field vector from a magnetic dipole in the head and generates a respective detected signal based on the respective magnetic field vector. Each three-axis gradiometer is disposed at a respective position of the shell. The computing portion determines a location of the magnetic dipole based on the first detected signal, the second detected signal and the third detected signal.

Magnetoencephalography system and method for 3D localization and tracking of electrical activity in brain

A blast tube includes three portions and three diaphragms. The first portion has a first length and a first cross section. The second portion has a second length and a second cross section. The third portion has a third length and a third cross section. The first diaphragm is disposed between the second portion and the third portion and switches from a closed state to an open state at a first time. The second diaphragm switches from a closed state to an open state at a second time after the first time. The third diaphragm is disposed between the first portion and the second portion and switches from a closed state to an open state at a third time after the second time. The third portion is disposed between the first diaphragm and the second diaphragm.
