- For example, 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.
- 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.
- It is desirable that problems described previously are solved.
- In a first aspect of the invention there is provided 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.
- In the cabinet for an MRI system according to the above first aspect, 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. On the other hand, of the components for the MRI system, 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. Besides, since 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. Further, since water cooling is performed for only the water-cooled component, moisture condensation caused by supercooling does not occur.
- In a second aspect of the invention there is provided, in combination with the above first aspect, 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.
- Therefore, in the cabinet for an MRI system according to the above second aspect, 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.
- In a third aspect of the invention there is provided, in combination with the above first or second aspect, 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.
- Therefore, in the cabinet for an MRI system according to the above third aspect, the cooling water of an increased temperature is conducted outdoors, allowing its heat to be dissipated outdoors. Thus, it is possible to prevent the dissipated heat from exerting a bad influence on the indoor environment.
- In a fourth aspect of the invention there is provided, in combination with any of the above first to third aspects, 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.
- When the transfer of heat is performed between the interior and the exterior through a cabinet case, there may occur a case where one exerts a bad influence on the other.
- Therefore, in the cabinet for an MRI system according to the above fourth aspect, the interior and the exterior of the cabinet are heat-insulated using a heat insulating material. As a result, 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.
- In a fifth aspect of the invention there is provided, in combination with any of the above first to fourth aspects, a cabinet for an MRI system including a digital signal processing circuit as the electronic part of the air-cooled component.
- In the cabinet for an MRI system according to the above fifth aspect, not water cooling, but air cooling is performed for a digital signal processing circuit which generates heat in a smaller quantity than a power circuit. As a result, it is possible to prevent the digital signal processing circuit from being supercooled.
- In a sixth aspect of the invention there is provided, in combination with the above fifth aspect, a cabinet for an MRI system wherein the digital signal processing circuit includes a CPU and a memory.
- In the cabinet for an MRI system according to the above sixth aspect, not water cooling, but air cooling is performed for a CPU and a memory both generating heat in a smaller quantity than the power circuit. As a result, it is possible to prevent the CPU and memory from being supercooled.
- In a seventh aspect of the invention there is provided, in combination with any of the above first to sixth aspects, a cabinet for an MRI system including a power circuit as the electronic part of the water-cooled component.
- In the cabinet of an MRI system according to the above seventh, not air cooling, but water cooling is performed for a power circuit which generates a large quantity of heat. As a result, the power circuit can be cooled sufficiently.
- In an eighth aspect of the invention there is provided, in combination with the above seventh aspect, a cabinet for an MRI system wherein the power circuit includes an RF amplifier and a gradient amplifier.
- 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.
- In the cabinet for an MRI system according to the invention, of the components for the MRI system, a component for which air cooling suffices is cooled with cold air blown down from the cooler outdoor machine, while a component to be cooled with water is cooled with cooling water, 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.
- Further objects and advantages of the present invention will be apparent from the following description of the preferred embodiments of the invention as illustrated in the accompanying drawings.
