Capitalizing on (i) the Chemical Exchange Saturation Transfer (CEST)-MRI contrast mechanism that allows the use of small bioorganic molecules as MRI sensors, (ii) the frequency encoding
, color-like features of CEST, and on (iii) enzyme engineering procedures that allow the optimization of enzymatic activity for a desired substrate, a multicolor genetically encoded MRI reporter system is proposed.
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 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.
Utilizing Dual Motion Frequency Encoding
, the DIVA IPG has isolated high motion from low motion frequencies which allows the blending of data and full motion video in one screen.
The gradient coils produce images from signals coming from the subject through frequency encoding
of the MR signal.
