Abstract

To increase selectivity of activation autoradiography for the first time it has been suggested to use computer’s processing of time series of autoradiography images obtained while the sample is cooling. To preserve the spatial resolution of the method, the processing must involve all coaxial pixels of the series. For visualization of the obtained results a cross section method for generation of a set of metaimages has been developed. The generated metaimages characterize the spatial distribution of pixels for half-life values lying in the selected interval. The algorithm for testing the computational data compatibility within the preselected zone has been developed. The algorithm is based on analysis of frequency distribution of half-life values for pixels array composing the sample zone under testing. The normal distribution characterizes compatible data for homogeneous part of the sample. Using the frequency analysis, a method for generation of contrasted metaimages has been developed. The method is able to distinguish zones with half-life differences of about 1 h.
