In the MRI system, the receiving coil is an important component, which directly affects the quality of the image. Receive coils are responsible for detecting the MR signal. The oscillating net magnetic flux from the excited spin system can be captured by the coil in which an induced electric current is generated. This current is then amplified, digitized, and filtered to extract frequency and phase information.
After years of unremitting research and hard work, our company’s R&D team has developed its own receiving coil through various repeated tests and comparisons, and its performance indicators have reached the industry’s leading level.
We have many types of receive coils to choose from, which can be classified according to the appearance, which can be divided into surface, birdcage, and transceiver coils. In addition, the user can select the number of channels of the coil as needed,
Generally, birdcage coils are the most widely used, and can be used on the head, neck, knees, etc.; for example, the two-channel birdcage coil is composed of solenoid coils and saddle coils. Our coils have high quality factors and good uniformity, Can meet a variety of scanning needs, at the same time, we also provide customized services, users can choose the size by themselves.
The surface coil can be used to scan the spine or other parts of interest; when using the surface coil, due to its openness, you can scan the area of interest in different postures.
The transceiver coil is a new type of coil. Its transmitting and receiving are integrated, so the size of the coil is smaller than common coils. Under the same conditions, compared with the traditional transceiver separated system, it has smaller requirements on the power of the RF power amplifier. In addition, due to its small size, it does not require large magnet opening size, and can be used for small system or other systems with strict space requirements.
