Benefits of technology

[0030]In the cabinet for an MRI system according to the above eighth aspect, not air cooling, but water cooling is performed for an RF amplifier and a gradient amplifier both generating a large quantity of heat. As a result, the RF amplifier and the gradient amplifier can be cooled sufficiently.

Problems solved by technology

Therefore, in case of air-conditioning a room with components for an MRI system installed therein to maintain the temperature of components for the MRI system at an appropriate temperature as in the above conventional surface temperature adjusting method for a magnet for an MRI system, if the air conditioning is performed in conformity with the quantity of heat generated from the memory, there occurs insufficiency for the gradient amplifier.
On the other hand, if the air conditioning is performed in conformity with the quantity of heat generated from the gradient amplifier, there occurs excess for the memory or an increase of noise of a fan which rotates at high speed for ensuring a required wind volume.
Cooling the components for the MRI system with water is considered as a solution to this problem, but if water cooling is performed in conformity with the quantity of heat generated from the memory, there occurs insufficiency for the gradient amplifier.
On the other hand, if water cooling is performed in conformity with the quantity of heat generated from the gradient amplifier, there occurs excess for the memory, with a consequent fear of moisture condensation due to supercooling.

first embodiment

[0037]FIG. 1 is a block diagram showing a functional configuration of an MRI system 100 according to a first embodiment of the invention.

[0038]In the MRI system 100, a magnet assembly 1 has a spatial portion (bore) for insertion therein of a subject and includes, in a surrounding relation to the spatial portion, an X-axis gradient coil 1X for forming an X-axis gradient magnetic field, a Y-axis gradient coil 1Y for forming a Y-axis gradient magnetic field, a Z-axis gradient coil 1Z for forming a Z-axis gradient magnetic field, a transmission coil 1T to provide RF pulses for exciting a spin of an atomic nucleus in the subject, a receiving coil 1R for detecting an NMR signal generated from the subject, and a pair of permanent magnets 1M for forming a static magnetic field.

[0039]Superconducting magnets may be used instead of the pair of permanent magnets 1M.

[0040]The X-axis gradient coil 1X, Y-axis gradient coil 1Y, Z-axis gradient coil 1Z and transmission coil 1T are connected to an X-...

second embodiment

[0058]Propylene glycol or ethylene glycol may be used as cooling water.

Abstract

With a view to cooling components for an MRI system neither more nor less and without the generation of noise or without a fear of moisture condensation, a component for which cooling with air suffices, out of the components for an MRI system, is cooled as an air-cooled component with cold air which is blown down from an air conditioner indoor machine, while a component to be cooled with air, out of the components for an MRI system, is cooled with cooling water.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a cabinet for an MRI (Magnetic Resonance Imaging) system and more particularly to a cabinet for an MRI system able to cool components for the MRI system neither more nor less and without generating a noise or without a fear of moisture condensation.[0002]Heretofore there has been known a surface temperature adjusting method for a magnet for an MRI system which method detects the temperature of the magnet and air-condition a room where the MRI system is installed to maintain the temperature of the magnet at an appropriate temperature (see, for example, Patent Literature 1).[0003]A power supply unit for an air-cooled type MRI system is also known (see, for example, Patent Literature 2).[0004]Further known is an MRI system wherein a coil is water-cooled (see, for example, Patent Literature 3).[0005][Patent Literature 1] Japanese Unexamined Patent Publication No. Hei 6 (1994) -165766[0006][Patent Literature 2] Japanese Un...
