ABSTRACT:
A scintillator detector array particularly useful in computerized tomography comprises a housing including a plurality of walled cellular chambers, said housing having a front wall member transmissive to x-ray radiation and whose chambers are defined by side wall members comprising materials, such as tungsten and tantalum, which are substantially opaque to x-ray radiation. Within the housing there is disposed a liquid scintillation medium including a soluble fluor and solvent material for the fluor. The solvent may comprise either an intrinsically high Z solvent or may be a solvent which has dissolved therein a high Z compound. Also disposed about the cellular chambers are a plurality of photoelectrically responsive devices. The detector array operates to convert x-ray intensity levels of impinging x-ray radiation to related electrical signal intensity levels.
