The concept I am looking for is the acoustic modulation of a source region in a magnetic resonance imaging system, then demodulation of the mri signal. This is the same approach used for modulating visual images presented to a person, then extracted from the fMRI images the code sequence that tells where someone is looking. Each region has its unique signature. Acoustic, particularly ultrasonic, encoding of regions would allow for spatial encoding and decoding, where the active acoustic modulation replaces the magnetic gradients in current MRI.
