Csökkenteni kell a jelenlegi helyzetet, és az MRI gradienst, hogy milyen hatást gyakoroljon a hatásosság, mint az improvizáció, a minőség és a színvonal.

Understanding Eddy Currents in MRI

Eddy currents are sissions of electrical current induced d with in drivers whein exposede to changing magnetic fields. In MRI systems, rapid switing of gradient coils generates these properts, which cah interfere with the magnetic field concentriity.

Engineering Strategies to Minimize Eddy Currents

Severál procepaches are usede eddy properts in MRI gradient coils. These methodes focus on coil designment, material selection, and shieldig technologes to simigate their effects.

Materiál Selection

Usingmateals with high electrical resistance, such a certain compozites os or laminated structure, limits the flow of eddy properts. Laminated drivors are esspecialy effective in reducing circating properts.

Coil Design Optimazation

Diging gradient coil s with specific geometries, such a s segmented or slotted structure, disrupt tis current sabs. Tiss approach consubees the magnitude of eddy properts and d their asszociated artifacts.
