Real-time PET? (Feasibility of Direct Neural Control using PET scan)

I am interested in know how feasible Positron Emission Tomography (PET)
scan can be used in real-time based systems. And how portable the unit
can be made (say in 10 years.) 

I have formulated several rough schemes to train the brain to responde 
to different regions which can then be used as a certain coding scheme. 
While at Georgia Tech, I worked with Mike Furman using EEG, signal 
processing, and Neural Net trying to locate the patterns. Due to the 
summated neural response nature of EEG and the inherent attenuations of 
the fields, the signals are not clean enough. Thus, I am looking at
several other alternative schems. One of which is using the blood-flow.

PS.If you were following the thread on "fast MRI an lucid dream 
proposals...", you may know that I've responded in several posts and 
am aware of some of the limitations of PET.
