| 内容記述 | Coherent-scatter computed tomography (CT) is a technique that produces images based on low-angle X-ray coherent scatter. The number of coherent-scatter photons corresponding to the scattered angles is sensitive to the molecular structure, and hence, their contrast properties on CT images are expected to be higher at specific angles. However, very few studies have reported such image contrasts. Therefore, we attempted to evaluate and compare the contrast properties of coherent-scatter CT images with those of conventional CT images. First, simulation studies using coherent-scatter distributions were performed with monoenergetic beams of 30, 60, and 90 keV, and a polyenergetic beam of 40 kV. This was followed by an experimental study using coherent-scatter CT images with a plastic phantom measuring 6 cm in diameter radiated by a polyenergetic beam of 40 kV. The relative contrast in coherent-scatter CT images at a low-scatter angle was higher than that in conventional CT images. This result suggests that coherent-scatter CT is useful in the detection of low-contrast lesions. | |||||
