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.
