Abstract:
1. An acoustography dynamic range extending device which avoids long-troubling distortions to extend the dynamic range of acoustography, the device comprising: A) an acoustographic system having a light sensor for viewing, and capturing exposures of, an acousto-optic sensor while ultra-sound is incident on the acousto-optic sensor; and B) dynamic range extending instructions encoded in an information bearing medium readable by an information system, the dynamic range extending instructions having components comprising: i) a threshold component for causing the information system to determine thresholds to reach a preset brightness for each light sensor pixel in recorded exposure data recorded in the information system, ii) a transformation component for causing the information system to transform thresholds data to image data (I) by a transformation I=f (t iii) a report component for causing the information system to output image data.
