We developed an embossed radiography system utilizing single- and dual-energy subtractions for decreasing the absorption contrast of unnecessary regions, and contrast resolution of a target region was increased using image-shifting subtraction and a linear-contrast system in a flat panel detector (FPD). To carry out embossed radiography, we developed a computer program for two-dimensional subtraction, and a conventional x-ray generator with a 0.5-mm-focus tube was used. Energy subtraction was performed at tube voltages of 42.5 and 70.0 kV, a tube current of 1.0 mA, and an x-ray exposure time of 5.0 s. Embossed radiography was achieved with cohesion imaging by use of the FPD with pixel sizes of 48 ×48 μm, and the shifting dimension of an object in the horizontal and vertical directions ranged from 48 to 144 μm. We obtained high-contrast embossed images of fine bones and coronary arteries approximately 100 μm in diameter.
