摘要：

A dual-energy technique which employs the basis decomposition method is being investigated for application to digital mammography. A three-component phantom was doubly exposed with the digital mammography system manufactured by General Electric. The "low" and "high" energy images were recorded with a Mo/Mo anode-filter combination at 25 kV and a Rh/Rh combination at 40 W, respectively. The total dose was kept within the acceptable levels of conventional mammography. The first hybrid image obtained with the dual-energy algorithm is presented in comparison with a conventional radiograph of the phantom.
