The 'colorimetric technique' that maps four dimensions (4D) of brain data using EEG signal...

January 23, 2009 It’s kind of ironic that the very organ that gives us our intelligence and understanding of the world around us is also the one we understand the least. Now a novel 4D colorimetric technique developed by researchers at Florida Atlantic University, (FAU), that simultaneously maps four dimensions of brain data, (magnitude, 2D of cortical surface and time), in EEG signals could dramatically change the way neuroscientists are able to understand how the brain operates. The technique makes it possible to observe and interpret oscillatory activity of the entire brain as it evolves in time, millisecond by millisecond, so that for the first time, true episodes of brain coordination can be spotted directly in EEG records and carefully analyzed.  Read More

CT dose reduction technology uses military technology

December 1, 2008 The CereTom portable CT scanner is remarkable, but the latest improvement to the remarkable machine comes entirely through software – it’s a Noise/Dose Reduction solution for medical imaging. NeuroLogica’s CT post reconstruction filter is similar to military synthetic aperture radar systems which filter out “noise” while preserving signal quality to thus better “see” objects. These algorithms are computationally intensive but thanks to Moore’s Law and the advent of ever faster, inexpensive computers, we’ll inevitably see many new smarts being added to existing machines. The ingenious solution reduces image noise while preserving spatial resolution and noise texture. The advantage offered by the technology is in significantly reducing accumulated exposure of critical and pediatric patients to radiation without sacrificing image quality.  Read More
