Webb2 apr. 2024 · Typically, the B 1 field is approximately 25 μT. This means that the radiofrequency pulse must be applied for approximately 0.23 ms to achieve a selective 90 degree rotation of the magnetization vector. Transmit coils are also capable of receiving radiofrequency and thus also act as receiver coils. Webb22 okt. 2024 · To ensure RF safety, a conservative worst-case SAR scenario was assumed, 31 resulting in average power limits of 4W per channel to achieve the 20W/kg SAR limit of the IEC guidelines for any phase setting.
