- Patent Literature 1 Japanese Unexamined Patent Publication No. Hei 6 (1994) -165766
- Patent Literature 2 Japanese Unexamined Patent Publication No. 2000-139873
- Patent Literature 3 Japanese Unexamined Patent Publication No. 2004-267405
- a memory and a gradient amplifier are considered as components for an MRI system.
- the quantity of heat generated from a gradient amplifier is several times as large as that of a memory.
- 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.
- a cabinet for an MRI system comprising an indoor machine of a cooler adapted to blow down cold air, an air-cooled component including an electronic part installed below the cooler indoor machine and cooled with the cold air, and a water-cooled component including an electronic part installed below the air-cooled component and cooled with circulating cooling water.
- a component cooled sufficiently with air out of the components for the MRI system is cooled as an air-cooled component with cold air which is blown down from the cooler indoor machine.
- a component to be cooled with air is cooled with cooling water as a water-cooled component. That is, the components for the MRI system can be cooled neither more nor less.
- air cooling is performed for only the air-cooled component, it is not necessary to rotate a fan at high speed and hence a noise does not occur.
- water cooling is performed for only the water-cooled component, moisture condensation caused by supercooling does not occur.
- a cabinet for an MRI system wherein the heat of the cooler indoor machine is discharged outdoors by an outdoor machine of the cooler.
- the heat from the cooler indoor machine may be discharged indoors, but the discharged heat may exert a bad influence on the indoor environment.
- the heat from the cooler indoor machine is discharged outdoors by the cooler outdoor machine. Therefore, it is possible to prevent the discharged heat from exerting a bad influence on the indoor environment.
- a cabinet for an MRI system wherein the cooling water circulates from the water-cooled component to the outdoors with dissipation of heat and then returns to the water-cooled component.
- the heat from the cooling water of an increased temperature may be dissipated indoors, but the dissipated heat may exert a bad influence on the indoor environment.
- the cooling water of an increased temperature is conducted outdoors, allowing its heat to be dissipated outdoors.
- the dissipated heat from exerting a bad influence on the indoor environment.
- a cabinet for an MRI system further comprising a heat insulating material for heat-insulating the air-cooled component and the water-cooled component from the exterior.
- the interior and the exterior of the cabinet are heat-insulated using a heat insulating material.
- the transfer of heat can no longer be performed between the interior and the exterior of the cabinet and it is possible to prevent one from exerting a bad influence on the other.
- a cabinet for an MRI system including a digital signal processing circuit as the electronic part of the air-cooled component.
- a cabinet for an MRI system wherein the digital signal processing circuit includes a CPU and a memory.
- a cabinet for an MRI system including a power circuit as the electronic part of the water-cooled component.
- a cabinet for an MRI system wherein the power circuit includes an RF amplifier and a gradient amplifier.
- each component can be cooled neither more nor less. Besides, since air cooling is performed for only the air-cooled component, it is necessary to rotate the fan at high speed and hence a noise does not occur. Likewise, since water cooling is performed for only the water-cooled component, moisture condensation caused by supercooling does not occur.
- the cabinet for the MRI system according to the invention can be utilized for obtaining a tomographic image of a subject.
- FIG. 1 is a block diagram showing a functional configuration of an MRI system according to a first embodiment of the invention.
- FIG. 2 is a schematic perspective view showing a cabinet for the MRI system according to the first embodiment.
- FIG. 1 is a block diagram showing a functional configuration of an MRI system 100 according to a first embodiment of the invention.
- 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 1 X for forming an X-axis gradient magnetic field, a Y-axis gradient coil 1 Y for forming a Y-axis gradient magnetic field, a Z-axis gradient coil 1 Z for forming a Z-axis gradient magnetic field, a transmission coil 1 T to provide RF pulses for exciting a spin of an atomic nucleus in the subject, a receiving coil 1 R for detecting an NMR signal generated from the subject, and a pair of permanent magnets 1 M for forming a static magnetic field.
- Superconducting magnets may be used instead of the pair of permanent magnets 1 M.
- the X-axis gradient coil 1 X, Y-axis gradient coil 1 Y, Z-axis gradient coil 1 Z and transmission coil 1 T are connected to an X-axis gradient coil driver 3 X, Y-axis gradient coil driver 3 Y, Z-axis gradient coil driver 3 Z and RF power amplifier 4 , respectively.
- the X-axis gradient coil driver 3 X, Y-axis gradient coil driver 3 Y, Z-axis gradient coil driver 3 Z and RF power amplifier 4 include an X-axis gradient amplifier, Y-axis gradient amplifier, Z-axis gradient amplifier and RF amplifier, respectively.
- a sequence memory 8 operates the gradient coil drivers 3 X, 3 Y and 3 Z on the basis of a pulse sequence stored therein, causing gradient magnetic fields to be generated from the gradient coils 1 X, 1 Y and 1 Z, and at the same time operates a gate modulator 9 to modulate a carrier output signal provided from an RF oscillator 10 into a pulse signal having a predetermined timing, a predetermined envelope shape and a predetermined phase.
- the pulse signal is then applied as an RF pulse to an RF power amplifier 4 , in which it is power-amplified, then the thus-amplified signal is applied to the transmission coil 1 T.
- the receiving coil 1 R is connected to a preamplifier 5 .
- the preamplifier 5 amplifies an NMR signal provided from a subject and received by the receiving coil 1 R and inputs it to a phase detector 12 .
- the phase detector 12 detects the phase of an NMR signal provided from the preamplifier 5 and provides the detected signal to an AD converter 11 .
- the AD converter 11 converts an analog signal after the phase detection into digital data and inputs the digital data to the computer 7 .
- the computer 7 not only takes charge of an overall control such as receiving information inputted from an operator console 13 , but also reads digital data from the AD converter 11 , performs an arithmetic operation to generate an image and display the image and a message on a display 6 .
- the computer 7 includes a CPU and a memory.
- FIG. 2 is a schematic perspective view showing the configuration of a cabinet 200 for the MRI system according to the invention.

- a cooling water pipe 62 leaves the water-cooled component 50 , extends through the wall W and gets into a cooling water pump chiller 61 disposed outdoors. Cooling water whose temperature has risen within the water-cooled component 50 passes through the cooling water pipe 62 , gets into the cooling water pump chiller 61 , dissipates heat in the cooling water pump chiller 61 to reduce the temperature thereof, then passes through the cooling water pipe 62 and returns to the water-cooled component 50 .
