Abstract
According to certain embodiments of the present invention, there is provided a magnetoencephalography and method employing a portable cart having a SQUID dewar mounted in an inverted manner thereon, and having a headrest assembly mounted on the cart for supporting the head of a patient and forming a portion of the dewar. The headrest assembly includes an array of magnetic sensors of the SQUID dewar for responding to electrical activity of the brain of the head.
Claims38
A magnetoencephalography system, comprising:
- a portable cart for moving along the ground;
- a SQUID dewar mounted in an inverted manner on the cart;
- a headrest assembly mounted on the cart and having a headrest for supporting a head of a patient and forming a portion of the dewar;
- the headrest assembly includes an array of magnetic sensors of the SQUID dewar for responding to electrical activity of the brain of the head;
- and
- a patient bed mounted on the cart adjacent to the headrest for supporting the body of the patient with his or her head supported by the headrest.
A headrest assembly for a magnetoencephalography system, comprising:
- a concave headrest assembly having a headrest for supporting a head of a patient;
- an array of ultra high spatial resolution cryocooled superconducting sensors disposed adjacent to the headrest for responding to electrical activity of the brain of the head;
- and
- said headrest being configured in an elipsoid shape having a sagittal radius of curvature of between about 80 millimeters and about 100 millimeters for the sagittal axis of the head and having a coronal radius of curvature of between about 60 millimeters and about 90 millimeters at the coronal axis of the head.
A method of magnatoencephalography for the brain of a head of a patient, comprising:
- supporting the head on a headrest assembly including a headrest mounted on a cart having an array of magnetic sensors forming a part of an inverted SQUID dewar;
- supporting the body of the patient on a bed mounted on the cart;
- and detecting electrical activity of the brain of the patient.
