New nanocrystals can reduce x-ray radiation

Medical x-ray technology has been used for a long time and is the most common way and tool for obtaining high-quality x-ray images – and although it is unlikely that any of the patients will be able to reach the threshold of 10, 000 pulsations, which is dangerous, still the need for developing a technology that is obvious to everyone would allow to slightly reduce the dose of radiation received by the patient during the examination by x-ray. So, experts from the United States presented such a development that will reduce this threshold, while increasing the quality of x-ray images, and all this at a significantly lower cost of manufacturing and operation of the x-ray itself.

The old technology is based on the use of special inorganic nanocrystals for the so-called scintillators, which convert radiation energy into visible light – the basis of this chemical process is the ability to obtain highly detailed x-ray images. However, the manufacture of these nanocrystals is quite expensive and complicated, since it requires a lot of resources and a high temperature of manufacture.

That is why experts have introduced a new form of scintillators based on lead-halide perovskite material, which are significantly cheaper and easier to manufacture crystals. And unlike traditional inorganic crystals, new ones have a noticeably higher specific degree of conversion of radiation energy into visible light, which leads to noticeably better images – higher resolution for lower energy costs and the speed of the process. All this will allow specialists to radically improve X-Ray technology.

It is also worth noting that specialists are actively working to improve their nanocrystals and soon plan to further improve the quality of conversion of the radiation flux into visible light – which will result in a much higher image improvement. It remains to wait for the final results and thus focus on future thematic developments, which the team is probably thinking at the moment.
