Multiple window rectilinear scanner modification.
Although the gamma camera and multi-crystal scanner have largely replaced the old dual probe rectlinear scanners in the larger hospitals, a large number of such scanners are still in use today. Modifications to these units can greatly enhance their usefulness. This paper describes the addition of dual SCA windows to each probe of a rectlinear scanner to increase sensitivity to multiple gamma-ray isotopes such as 67Ga. This method allows increased information density and/or decreased scanning time without degrading image quality. NIM electronics are used to keep down capital costs, as these modules can be shared with other counting systems when multiple-peak isotopes are not being scanned. A simple connection to an Ohio Nuclear Mdl 84 dual probe scanner is described. For other scanners, a slight modification would be necessary.
