Abstract: The present disclosure provides a gamma camera imaging method and a gamma camera imaging device. The method includes: selecting, from energy spectrums captured by a gamma camera on one or more radioactive materials, one or more energy ranges of each radioactive material among the one or more radioactive materials as one or more monitored energy regions of the radioactive material; performing image reconstruction on the monitored energy regions of each radioactive material among the one or more radioactive materials; performing normalization on images obtained through the image reconstruction; and performing superimposing on the normalized images to form a composite image.
