Used magnetic resonance imaging of the magnet magnetic?
Magnetic resonance imaging system used in the hospital now, one of the largest and most important part is the magnet.
Rated using the unit of measurement known as the tesla magnets, magnetic resonance imaging system.
Another common unit of measure is gaussian with magnet.
MRI magnet at 0.
5 to 3 tesla.
0 tesla range to use (
From 5000 to 30000 gauss)
The most powerful magnet can be as high as 60 tesla, studies have shown that with the earth up to 0.
5 gauss magnetic field!
Because the magnet magnetic force, magnetic resonance imaging (fmri) suite can be a very dangerous action, not strictly abide by the metal objects can become dangerous radiation, such as paper clips, pens, keys, hemostatic forceps, stethoscopes and other metals into the scanning chamber, will be virtually hurt body, will be at very fast speed, pose a threat to everyone in the room.
The magnetic resonance imaging system, such as credit CARDS, bank CARDS, and any other magnetic coding will be deleted.
Applying magnetic object multiplied, because it is close to the magnet.
Imagine standing in 4.
6 meters place, the distance of the tongs magnets in hand, you will feel a slight pulling force.
When standing in 1 m, wrench may pull away from you in the past, it may be more massive object, more dangerous.
Strength and its magnets attract much stronger.
Mop bucket, vacuum cleaner, four bar, oxygen tanks, patient stretcher, heart monitors and countless other objects are being dragged into an MRI machine field, small objects by hand.
Likely to pull a winch, or closed magnetic field to pull out.
In patients with admission into the scanning room or staff, thoroughly screening - metal object
Not only the external object.
Usually, the patient implant in them, so they can in the presence of strong magnetic field, it is very dangerous.
In the metal fragments of the eye is very dangerous, because mobile pieces like these can lead to eye damage or blindness.
People with heart pacemaker can't be scanned, and even to near the scanner, because the magnet can lead to cardiac pacemaker malfunction.
In the brain aneurysm clipping is very dangerous, the magnet can move them, make them tore very artery were placed in their repair.
MRI magnetic field is incredibly powerful.
Take off into the MRI machine arms and a watch, it is possible.
