Tomasi Física, Astronomía y Matemáticas knee MRI high field birdcage coil electromagnetic simulation The radiofrequency coil is a crucial component of the magnetic resonance imaging scanners, so that a solid knowledge on the design andphysical characteristics is important for those interested in its development. A birdcage coil with a 10 cm radius and 4 legs (length = 12cm),and a separation between the copper strips of 4 cm, was developed for magnetic resonance imaging (MRI) of the human knee and tuned atthe resonance frequency of protons at 4 Tesla (170.3 MHz). MR images were acquired with this coil in phantoms and in the knee of a healthyvolunteer using a standard spin echo sequence, The phantom images demonstrated the high uniformity of the radiofrequency field with highsignal-to-noise ratio, a characteristic of all birdcage RF coils. The in vivo knee images demonstrated that this birdcage geometry is ideal forknee imaging, promising MR images of the knee with higher spatial resolution at 4 Tesla.
