What is a common example of a transmit/receive coil used in MRI?

A transmit/receive coil is an essential component in MRI systems, as it directly influences the quality of the images produced. The common example of a transmit/receive coil that stands out is the head coil, which is specifically designed for imaging the brain.

Head coils generally provide optimal signal reception from the brain area due to their shape and design, allowing for high-quality imaging of neural structures. They function by both transmitting radiofrequency pulses to excite the hydrogen nuclei and receiving the signals emitted from these nuclei when they relax. This dual functionality makes the head coil a primary example of a transmit/receive coil in clinical practice.

The quad CP extremity coil and body coil are also transmit/receive coils, but they serve different anatomical areas and may not be as universally recognized as the head coil in clinical settings. Spiral coils are less commonly referenced in general practice compared to the other options and may not serve the typical function or application expected in an MRI context. Thus, the head coil is often identified as a cornerstone example of transmit/receive coils used in MRI.
