摘要： An MRI apparatus with an enhanced thermal control system, the apparatus including:
a static magnetic field generation unit with at least two magnetic poles at a predetermined distance and forming a gantry for housing an object to be imaged;
one heater for heating the magnetic poles and/or the magnetic yoke;
one or more temperature sensors measuring the temperature of the at least one pole and/or of the yoke;
a thermal control unit, including:
a processing unit, with control software;
the processing unit having input ports for receiving temperature measurement signals from the one or more temperature sensors;
the processing unit having output ports for feeding driving signals to the one heater;
the control software including instructions to generate the driving signals of the one heater.-

摘要： Magnetic field sensor, in particular for measuring magnetic noise fields caused by environmental magnetic noise in combination with MRI apparatus, the magnetic field sensor being further provided with field compensation coils assembly and with a compensation circuit driving the field compensation coils assembly to generate a magnetic field compensating the static magnetic field dissipating outside from the static magnetic field generator or from the gantry of the MRI apparatus at the position of the magnetic sensor. A method for operating the magnetic field sensor and a method and a system for compensation magnetic noise caused by environmental noise are also provided. An MRI apparatus is also disclosed comprising such a system and carrying out such a method for compensating magnetic noise fields.
