1. A signal processing method in autoradiography for obtaining information at a one dimensional location of radioactively labeled substances distributed in at least one dimensional direction on a support medium, the information being in the form of symbols, numerals and combinations of the numerals and the symbols,which comprises a process including:

  • (1) determining a one dimensional scanning line for signal processing; and

    (2) detecting sampling points on said scanning line,said process being applied to digital signals corresponding to an autoradiograph having the locational information on the radioactively labeled substances, said digital signal being obtained by causing a stimulable phosphor sheet to absorb radiation energy emitted by said radioactively labeled substances on the support medium to record the autoradiograph of the radioactively labeled substances on the stimulable phosphor sheet, scanning said stimulable phosphor sheet with an electromagnetic wave to release at least a portion of the radiation energy stored in said phosphor sheet in the form of the autoradiograph as stimulated emission, and detecting said stimulated emission photoelectrically.
