Abstract
Systems, methods and apparatus are provided through which in some embodiments a thermal sensor of a magnetic coil of a magnetic resonance imaging system (MRI) is positioned, placed and/or mounted externally to the magnetic coil. The external placement of the thermal sensor does not require replacement of the entire magnetic coil, yielding less expensive replacement of a failed thermal sensor.
Claims20
An apparatus for monitoring internal temperature of a gradient coil, the apparatus comprising:
- a thermally conductive device having a first end and a second end, the first end positioned inside the gradient coil and the second end positioned outside the gradient coil;
- and
- a thermal sensor thermally coupled to the second end of the thermally conductive device external to the gradient coil.
A system for monitoring internal temperature of a gradient coil, the system comprising:
- at least one temperature monitoring apparatus comprising:
- a thermally conductive device having a first end and a second end, the first end positioned inside the gradient coil and the second end positioned outside of the gradient coil;
- and
- a thermal sensor thermally coupled to the second end of the thermally conductive device external to the gradient coil;
- and
- a control computer coupled to the thermal sensor and configured to receive signals from the thermal sensor.
