System for acquiring images in intraoperative magnetic resonance

A system for acquiring images by intraoperative magnetic resonance imaging, including fir acquiring progress state control images during brain surgery, the system comprising:

• a magnetic structure generating a static magnetic field and delimiting or surrounding, on at least some sides, a housing space for at least a patient's head;
• and
• a bed that is movable in different relative positions with respect to the magnetic structure, said positions being comprised between at least an end position, in which said bed is at least partially inside the housing space, and an outer end position in which said bed is outside said housing space and at a predetermined distance from the magnetic structure,
• wherein said magnetic structure has a cross-section that is U-shaped or C-shaped, in which the magnetic structure has at least one vertical connection element of two horizontal wall elements which are mutually vertically superimposed and are supported cantilevered and at a predetermined distance from each other by said vertical connection element, said vertical connection element eccentrically connecting, at a lateral edge, to said horizontal wall elements, said horizontal wall elements and said vertical connection element delimiting at a top, at a bottom and over at least one vertical lateral section a housing space for at least one portion of a patient's body, said horizontal wall elements carrying static magnetic field generating means that permeate said housing space, and
• wherein said bed has one end external to the magnetic structure and provided at a predetermined distance therefrom, said one end being supported cantilevered towards an opposite end by a column which is connected to the bed in an area of said external end and is rotatable about a vertical axis that coincides with or is parallel to an axis of said column,
• thereby enabling the bed to be continuously oscillated for a predetermined angular path between two extreme positions,
• wherein in one of the two extreme positions, defined as an imaging position, an end of the bed opposite the external end being provided with a patient's head positioning area and said external end being positioned inside the patient's housing space of the magnetic structure with the patient's head in correct image acquisition position with respect to the magnetic structure, and in another one of the two extreme positions, an end opposite to the said external end positioned at a predetermined distance from the magnetic structure and at the position of a surgical operating station, and
• wherein the angular path of oscillation of the bed is less than 90° and around only the vertical axis of rotation.
