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.
