How MRI Coils Function.

Improving Healthcare Outcomes with High-Quality MRI Coil Repair and Testing Services

MRI (Magnetic Resonance Imaging) is used to produce detailed images of organs, tissues, and bones within the body. It is commonly used to diagnose a wide range of medical conditions and injuries, including tumors, infections, joint injuries, and spinal cord injuries.

How does the MRI Coil work?

MRI coils are a critical component of the magnetic resonance imaging (MRI) machine. They work by detecting the radiofrequency (RF) signals that are emitted from the patient's body during the imaging process. The coils are made up of conductive wires that are wrapped in a particular shape, which determines their function.

Common types of coils used in MRI include:

  • Surface coils, which are placed directly on the part of the body being imaged

  • Body coils, which surround the entire patient

When the patient enters the MRI machine, the coils are activated, and a powerful magnetic field is applied to the body. This causes the protons in the body's water molecules to align with the magnetic field. Then, the MRI machine sends a radiofrequency pulse into the body, which excites the protons, causing them to emit RF signals.

These signals are detected by the coils, which then send them to the computer to produce an image for analysis. Different types of coils are used for different types of imaging, depending on the body part being imaged, and the issue type.

  • Surface coils are commonly used for detailed areas of the body, such as the brain or spine.

  • Body coils are used for larger areas, such as the torso.

There are many types of coils, each with its own unique shape and function, which allow for a wide range of imaging capabilities. Coils can be designed specifically for certain types of patients, such as those with larger body types, to ensure accurate imaging.

To surmise, MRI coils work by detecting the radiofrequency signals emitted by the patient's body during the imaging process. These signals are detected by the coils, which then send them to the computer for analysis, ultimately producing the final MRI image.

MRI coils are fragile and can be easily damaged if mishandled or dropped. However, if a coil is damaged, it can often be repaired and tested by specialized medical imaging equipment service companies such as ScanMed to give them additional life.

Regular maintenance and repair of MRI coils can help ensure that the equipment remains reliable and accurate, which is essential in providing high-quality medical imaging services.
