Signal processing method in autoradiography.

摘要

A signal processing method in autoradiography for obtaining information on one dimensional location of radioactively labeled substances distributed in at least one dimensional direction on a support medium in the form of symbol, numeral or combination thereof,
which comprises a process including:
<UnorderedLists id="ula01" listStyle="none"><ListItem>(1) preparing a graph in which position on a scanning line is set on abscissa and signal level is set on ordinate; and</ListItem><ListItem>(2) processing said graph with either or both of smoothing and threshold-processing to detect sampling points;</ListItem></UnorderedLists>
said process being applied to digital signal corresponding to an autoradiagraph having the locational information on the radioactively labeled substances, said digital signal being obtained by utilizing a radiation image recording and reproducing method employing a stimulable phosphor sheet.

A signal processing method for determining the base sequence of DNA is also disclosed.
