Multitracer Digital Autoradiography with MWPCs

A MWPC based detection system that is able to simultaneously reconstruct the two-dimensional distributions of two ß- tracers both of which are present in the sample is presented. The system consists of two superimposed MWPCs with a linear centroid detection filter and a digital image processing unit. With this system it will be possible to simultaneously measure more than one parameter (for example, metabolism and flow) from the same tissue sample.
