As the number of devices accompanying patients inside the MRI bore increases, so does the need for reliable powering inside the MRI. The high-power B1 field in MRI suggests the capability to harvest power wirelessly from the scanner itself. With high quality factor coils and a high efficiency class-E rectifier we are able to harvest 100s of µJ /TR. However, B1 harvesting will generate flip angle banding when harvesting loops are near imaging regions. These banding artifacts increase with increasing coil size and decrease with larger coil loading.
