  • Publication number: 20150289779
    Abstract: A system and method for automatic detection of potential focal cortical dysplasias through magnetic resonance imaging. The method includes acquiring image data of a subject brain at a first resolution, analyzing the acquired image data to determine a thickness of cerebral gray matter, and matching the left cerebral hemisphere to the right cerebral hemisphere based on corresponding geometric features of the hemispheres. The method also includes generating a difference map comparing corresponding thicknesses of the hemispheres, identifying regions of abnormal differences in thickness as potential regions containing focal cortical dysplasias, and acquiring image data of the regions of abnormal differences in thickness at a second resolution. The method further includes generating images of the regions of abnormal differences in thickness from the acquired image data and displaying the images.

  • Patent number: 4995036
    Abstract: A multichannel data compressor (20) for a data transmission system having a plurality of data sources. The multichannel data compressor has a plurality of data latches (44,46,48) for temporarily storing the data generated by each data source and a plurality of difference circuits (52,54,56), one for each data source, which subtract the data stored in the data latches from the next subsequent data value generated by the data sources to generate a difference data value. A plurality of summing circuits (58,60,62) sum the difference data values to generate a plurality of composite data values. A selector switch (64) transfers the composite data values or selected current data values to a multiplexer (72) when the magnitude of at least one of the composite data values exceeds a predetermined value. The multiplexer (72) formats the received data into a predetermined format, converts it to a serial format, then forwards the data to a transmitter for transmission.
