We developed a method which combines a scintigram and echogram(s) on the basis of precise positional correlation. In our method, an ordinary scintillation camera (Ohio Nuclear sigma 410S) and an ultrasound diagnosis equipment (Aloka Echo Camera) are used, both of which are connected through the interface made by us. This method presents a scintigram with dotted lines through which echograms have been taken, giving us more detailed inside information which we can not obtain from scintigram only. Also obtained are positional correlations between the organ of interest and its neighbouring organs. This method is easily applicable to ordinary scintillation cameras and is useful for our daily practice.
