The full k-space data with the size of 256 x 256 x 25 (number of frequency encoding
x number of phase encoding x number of frames) of the first dataset was acquired using a steady-state free precession (SSFP) sequence on a 1.5 T Philips scanner.
Figure 1(b) shows the ID-constellation diagram corresponding to the new temporal multi frequency encoding technique.
The proposed paper thus proves the use of temporal multi frequency encoding in chipless RFID applications.
The ten content chapters cover the following topics: the fundamentals of MRI; mathematics, physics, and imaging for MRI; basic physical principles; relaxation mechanisms; slice selection; frequency encoding
; phase encoding; the spin-echo imaging sequence; scan parameters for the spin-echo imaging sequence, and further imaging sequences.
The basic measurement technology for RF frequency encoding
is the microwave correlator.
One of the advantages of this type of channelizer is that different frequency encoding technologies can be used to process the outputs.
One receiver design concept is to combine the channelizers discussed above with the IFM receivers for frequency encoding. In this approach, the filter bandwidth can be relatively wide.
