【Abstract】 A new γ detecting probe device was described, which was used in radioguided surgery (RGS) for detecting tumor and its micrometastasis. The concrete scheme for this system was given in this paper and its performance was also evaluated. The animal experimental results showed that the γ detecting probe has excellent location resolution, and its collimator is practical.更多还原
