Although
birdcage coils are essential elements of modern MRI scanners, they have never
been miniaturized for placement inside body orifices such as the rectum and
used as inductively coupled coil elements. In this study, inductively coupled
birdcage coil (ICBC) and receive coupled birdcage coil (RCBC) are introduced
as internal coil. These coils can be used without modifying the scanner
hardware and do not affect tuning of external coils. ICBC coils are not
connected to the scanner by wires; rather the MR signal picked up by these
coils is transferred to a receiving coil by induction. Therefore, they are
system independent.
