The MR coil, one of the determining elements of image quality in Magnetic Resonance (MR) systems, collects signals from the patient and provides detailed and high-resolution images. However, in order for this important component not to lose its sensitivity over time, regular periodic calibration tests should be performed and repairs should be carried out when necessary. In this article, we will discuss the technical controls and service processes of MR coil systems.
As Anod, we provide the coil maintenance, testing and repair services that MR device users need the most with our professional equipment and experienced staff. Because the unhealthy operation of coil systems can directly affect the entire imaging process.
The Importance of MR Coil Calibration
The MR coil is one of the basic components that receive signals from the body and enable the creation of images. A coil with impaired calibration can cause signal losses, blurry images or completely dysfunctional results. This can lead to serious problems in terms of both patient safety and correct diagnosis.
During periodic calibration tests, the following parameters are checked:
Signal reception sensitivity
Frequency stability
Electromagnetic interference level
Cable connection performance
Physical deformation detection
Calibration processes are performed with special test phantoms and digital simulation systems. Thanks to these tests, the sensitivity of the coil is restored to its original values. It should be noted that coil systems in MRI devices require a higher level of technical maintenance, especially when compared to computerized tomography, x-ray and tomography devices.
Repair Process
Common problems encountered in MRI coil systems include:
Cable breaks or contact problems
Internal circuit damage
Physical cracks or crushing
Part deformations incompatible with the magnetic field
In the event of such failures, Anod technical service detects the faulty component and performs repair or replacement if necessary. The spare parts used are original products that are 100% compatible with the brand and model of the device. Thus, the safety and performance of the device are guaranteed.
Calibration Frequency and Technical Support
MR coil systems should be subjected to calibration tests at least once a year in intensively used healthcare institutions. Especially in systems where other imaging devices such as open MRI machines, mammography and X-rays are also connected, coil failures can affect the entire system.
As Anod, we ensure that the devices operate continuously and stably by creating periodic maintenance plans. Performance tests performed after the service ensure that the coil system operates smoothly.
As a result, MR coil periodic calibration tests and repair services are of great importance in order to maintain image quality and ensure device safety in MRI device systems. As Anod, we provide professional services in accordance with device manufacturer standards in these processes.
