WebHelium serves various purposes across a wide range of industries — the medical field is one of them. In fact, helium is commonly used in MRI machines and scanners. Liquid helium has a notably low boiling point of -269°C or around -452.2°F so it’s perfectly capable of cooling down MRI magnets. WebThree sets of gradient coils are used in nearly all MR systems: the x- , y-, and z-gradients. Each coil set is driven by an independent power amplifier and creates a gradient field whose z -component varies linearly along the x -, y -, and z -directions, respectively. The design of the z-gradients is usually based on circular (Maxwell) coils ...
