the present invention provides a scintillation camera comprising a scintillation material which is capable of converting high - energy radiation incident thereon and having a wavelength of x - ray radiation or shorter into optical radiation , at least one position - sensitive detector capable of detecting the optical radiation , and at least one bundle of light guides which is located in front of the detector , characterized in that the bundle of light guides is located between the detector and the scintillation material . as a result of the scintillation material being provided as a separate unit , optionally including non - scintillating light guides , selection of the materials of each of the two parts can be optimized . thus , for example , the scintillation material is no longer hygroscopic or subject to restrictions because of the need to grow it in parallel bundles .
