Image-guided radio-frequency gain calibration for high-field MRI.
High-field (≥ 3T) MRI provides a means to increase the signal-to-noise ratio, due to its higher tissue magnetization compared with 1.5T. However, both the static magnetic field (B(0)) and the transmit radio-frequency (RF) field (B 1+) inhomogeneities are comparatively higher at higher field strengths than those at 1.5T. These challenging factors at high-field strengths make it more difficult to...
متن کاملCalibration of Low-Frequency, Wide-Field Radio Interferometers Using Delay/Delay-Rate Filtering
We present a filtering technique that can be applied to individual baselines of widebandwidth, wide-field interferometric data to geometrically select regions on the celestial sphere that contain primary calibration sources. The technique relies on the Fourier transformation of wide-band frequency spectra from a given baseline to obtain onedimensional “delay images”, and then the transformation...
متن کاملIterative multi-channel radio frequency pulse calibration with improving B1 field uniformity in high field MRI
BACKGROUND In high field MRI capable of multi-channel radio frequency (RF) transmission, B 1 shimming is a time-consuming job because conventional B 1 shimming techniques require B 1 mapping for each channel. After acquiring the complex-numbered B 1 field maps, the optimal amplitude and phase of the driving RF pulse are determined for each channel to maximize the B 1 field uniformity in convent...
متن کاملAtom-Based Sensing of Weak Radio Frequency Electric Fields Using Homodyne Readout
We utilize a homodyne detection technique to achieve a new sensitivity limit for atom-based, absolute radio-frequency electric field sensing of 5 μV cm-1 Hz-1/2. A Mach-Zehnder interferometer is used for the homodyne detection. With the increased sensitivity, we investigate the dominant dephasing mechanisms that affect the performance of the sensor. In particular, we present data on power broad...
متن کاملDesign and Implementation of Field Programmable Gate Array Based Baseband Processor for Passive Radio Frequency Identification Tag (TECHNICAL NOTE)
In this paper, an Ultra High Frequency (UHF) base band processor for a passive tag is presented. It proposes a Radio Frequency Identification (RFID) tag digital base band architecture which is compatible with the EPC C C2/ISO18000-6B protocol. Several design approaches such as clock gating technique, clock strobe design and clock management are used. In order to reduce the area Decimal Matrix C...
