Abstract

The present invention relates to a use of bismuth ferrite crystals to detect a part of interest in biological samples. In order to provide a method which is cost-effective and in which a measurement can be carried out with a high degree of accuracy and which is quantifiable, the invention proposes that the part is marked with one or more bismuth ferrite crystals in a biological sample to be examined and the part marked in this manner is detected in the biological sample using at least one magnetic measuring method and at least one optical measuring method.

Abstract

The present invention relates to a scintillator element and a solid body detector, allowing an image display with a very high local resolution, having the greatest possible absorption force for the ionized radiation to be detected, and emitting the absorbed energy in a light pulse that is as brief as possible at a high conversion rate and at minimal luminescence, and also being substantially transparent to the wavelength of the maximum emission thereof. In order to attain this aim, the invention proposes that the scintillator element be made from a multi-layer structure having a passive carrier layer made from non-scintillating material and an active layer made of scintillating material that is applied onto the carrier layer.
