Built on a 175μm-thickness PET base, medical dry x-ray imaging clear blue base thermal film (DFF) combines the advantages of thermal imaging with the features of high-quality grayscale films. Combined with excellent image stability, the silver-free environmental imaging layer of the film is heat-sensitive rather than light-sensitive, guaranteeing low fog, low minimum density, reduced glare and light transmission, and high perceived contrast. Contributing to liner gradations from low-through-high density areas, the warm-toned imaging film in a variety of conventional practical sizes delivers optimum diagnostic image clarity for all image modalities as wet infrared laser films. The high-resolution, thermographic film is suitable for continuous-tone medical imaging to provide the aesthetic and diagnostic qualities, and sharp image rendition.
