For the past 25 years the design and configuration of array coils have evolved. The focus has been all about providing a better MRI
These multi-channel coils for MRI of the head, neck, shoulder, torso, wrist and beyond provide a receiver for each channel. They are available for both closed and open MRI systems. You can have a 4, 8, 16, 32, 64 or 128 channel system, with each increasing the number of receiver channels over traditional MRI coils.
Why Use a Phased Array MRI Coil?
That’s easy. It’s all about speeding up scan time. Very sophisticated MRI scans can take a very long time. However, with multiple channels, the scans can be performed 4-16 times faster. So, a scan that normally would take 60 minutes could take as little as 15—which provides a much better patient experience. With many MRIs, a patient is instructed to stay perfectly still and hold their breath for short periods of time. With quicker scan times, the patient can be more comfortable and less stressed.
The goal? More signal and less noise.
The ratio of signal to noise is used to evaluate coil performance and image quality. By using multi-channel technology, signal is increased, resulting in less noise and better scan quality. It’s true, you can also increase signal by using a 3T MRI system, but it’s much more economical to just purchase some multi-channel coils to use with your 1.5T scanner. Who doesn’t like to save money?
Patient comfort is key
When all the receiver channels are imaging at once, larger portions of the body are covered in each pass. This saves time and improves the patient experience—especially when doing spine work and vascular studies on legs.
If you want to get more out of a magnet without having to buy an entirely new system, upgrade your MRI coils! It will save money and improve patient experience. Furthermore, by using multi-channel coils, you can potentially Used Mri Scanners to replace the use of CT in some situations, since the MRI scans will be fast like CT but without the high-radiation dose.
