Slide 1

PXI-Based Magnetic Imaging System for Diagnosing Infant Brain Activity Tristan Technologies, Inc., San Diego, CA

Slide 2

Slide 3

Competing Methodologies Adult Magnetoencephalography (MEG) Multi-million dollar frameworks requiring extensive attractively protected rooms Poorer spatial determination fMRI Not genuinely "utilitarian" Poor time determination Requires babies to be calmed Contrast specialists frequently required PET Requires organization of radioisotopes may not be conceivable with newborn children Poor time determination EEG Lack of one of a kind source area Electrodes must be set on skull (tedious)

Slide 4

another approach to assess neurological hindrances of babies by attractive mapping 100% non-intrusive MEG (MagnetoEncephaloGraphy) Directly measures neural movement Portable – goes from healing facility lift to bedside Needs NO protected room

Slide 5

Data Acquisition System 24 bit determination 10 kSample/sec testing rate, synchronous 88 information channels, expandable Both equipment and programming supported Fiber optic information connect Multi-PXI arrangement as of now being produced
