Abstract
The present invention relates the system of the correction of energy crosstalk in dual-isotopes simultaneous acquisition (DISA), the system includes a collimator, a metal thin film, a detecting unit, an analyzing unit and a display unit for analyzing energy distribution charts of the dual-isotopes, and using specific equations or artificial neural network methods or independent component analysis to compare the energy distribution charts which are with and without metal thin film The invention uses the metal thin film to remove the energy contamination from dual-isotopes simultaneous acquisition whose photopeak energies are close, the invention effectively separates the energy distribution charts without energy crosstalk, therefore, the system improves diagnostic imaging and relieves patient's discomfort.
