Abstract

Last year’s ISOTT contained a report on the sensitivity of a phased array system for locating an object of .8 mm in a highly scattering medium at 3 cm within a highly scattering medium. Since then the sensitivity of the method has been exploited and detection of small objects as small as 40 microlitres containing 4 picomoles of absorber (cardiogreen) has been reportedl. Furthermore, a sharp phase transition and amplitude null has been verified in the human breast. (see Fig. 1)
