It is essential to increase the X-ray exposure efficiency to improve the image quality. To increase the efficiency, the Imaging Plate X-ray absorption has to be improved.
And to improve the Imaging Plate X-ray absorption, the phosphor layer thickness needs to be appropriately increased.
The Focused Phosphor Plate not only increased in thickness but also utilizes columnar-structured particles which act as a light guide, allowing the stimulating light to reach deep inside the phosphor layer.
The PSL (Photo Stimulated Luminescence) generated is then successfully extracted through the Focused Phosphor Plate surface. As a result, the X-ray exposure efficiency is improved.
