An MRI apparatus with an enhanced thermal control system, the said apparatus comprising:
- a static magnetic field generation unit with at least two magnetic poles supported one opposed to the other at a predetermined distance by a yoke and forming between them a gantry for housing an object to be imaged;
- at least one heater for heating the said magnetic poles and/or the said 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, comprising:
- a processing unit, with a memory in which a control software is loaded or loadable, the said control software being executed or executable by the said processing unit;
- said processing unit having input ports for receiving the temperature measurement signals from the said one or more temperature sensors;
- said processing unit having output ports for feeding driving signals to the said at least one heater;
- the said control software comprising the instructions for configuring the said processing unit to generate the said driving signals of the said at least one heater as a function of the signals related to measured temperatures by the said one or more sensors.
A method for carrying out thermal control of an MRI apparatus.
