The RFID chipless tag presented in this article uses a new technique for data encoding. It is based on changing the phase of multiple resonators that behave as phase shifter. This technique brings a much higher reliability than for the actual absence/presence of resonance encoding way. The design proposed is based on 5 reflective strip resonators having resonant frequency starting from 2.5 GHz to...
Phase Contrast MR Angiography (PC MRA) was used very powerful tools for diagnosis of blood vessel disease such as hemadostenosis, aneurism or flow velocity measurement. Many studies have been researched PC MRA application at high tesla MRI system because of main magnet field inhomogeneity and low signal to ratio (SNR) at low tesla MRI system. The purpose of this study is to develop the PC MRA pulse...
A new and novel spread spectrum approach employing orthogonal frequency coding (OFC) for a SAW sensor/tag is presented. This approach provides ultra wide band operation, multi-device interrogation, and reduced loss as compared to conventional SAW CDMA approaches. A traditional SAW CDMA tag consists of an input transducer that launches a surface wave on the substrate towards an array of single frequency...
The paper presents a novel approach of pseudo 2D random sampling scheme for application of compressed sensing in Cartesian magnetic resonance imaging (MRI). The proposed scheme is realized by a pulse sequence program which switches the directions of phase encoding and frequency encoding during data acquisition such that both kx and ky directions can be undersampled randomly. The resulting random sampling...
