In this article from ScanTeb website, we are going to explain about permanent MRI or MRI of the perment. According to the construction and special shape of this device, we will examine the capabilities, advantages and disadvantages of this highly functional device scientifically and professionally.
Different machine components:
Magnet is one of the most important components of MRI machines and the most important difference between permanent and supercontainer MRI devices is the magnet used in these two forms.
A permanent MRI magnet, as the name suggests, is made up of a permanent magnet like the same rod magnets as we all know, wrapped in a C-shaped shape and the two poles are close and parallel. In the space between the poles, the magnetic field is uniform enough for imaging.
A standard MRI permental magnet may require up to 30 tons of iron. Therefore, due to this high weight, which is a particular disadvantage of this device, a very strong flooring should be done in the magnet room or the place of installation of the device.
One of the most important components of medical imaging devices is their bed. In permanent MRI machines, their shape, weight, installation and location are of special importance. Considering that these models of devices are more widely used for imaging high-weight patients, the importance of the beds will be more visible.
The bed of MRI machines should bear a very high weight.
Gradient and mainly the gradient system of MRI machine is one of the most important components of this system in the formation of higher resolution images.
The more advanced the gradient system will help deliver higher resolution images. More advanced gradient system offers higher gradient intensity, faster imaging speed, shorter scanning time, thinner image cutting and higher image resolution.
Coil in permanent MRI machine
Due to the fact that the MRI machine has some limitations in some specialized MRI scans, it is not from a high range of coils.
Following are some of the coils of this device for MRI imaging:
– Coil Head
– Coil Neck
– Inflatable coil (body)
– Knee coil
– Shoulder coil
– Detailed coil
– Breast Coil
– Wrist coil
– Ankle coil
It should be noted that these coils are sold in some systems as options, and some devices offered in the market generally do not support these coils.
Advantages of Functional MRI Machine:
According to its user information, technical specifications and capabilities of different brands and models in the market, various advantages can be enumerated, but in general, this type of MRI machine has the following advantages:
No need for helium.
One of the most expensive consumables in an MRI machine is helium, due to the increase in exchange rates in recent years, the cost and price of helium in supercondective MRI machines has also increased, which has increased the ongoing costs of supercondective MRI imaging centers.
Functional MRI machines will not have the mentioned problems due to the lack of helium requirements. This can be one of the most desirable features of the device. This is especially important in the current era when consumable parts and helium are very expensive. It can be said that these devices do not have any consumption and extra costs on the magnet side. What’s so expensive and staggering, in super-condective MRIs.
