Method for representing concentration of contrast agent in predetermined volume portion of female breast, involves subtracting two dimensional low-energy image of female breast from two dimensional high-energy image

摘要

The method involves controlling the concentration of contrast agent and creating the two-dimensional low-energy image (1) and high-energy image of predetermined volume portion of female breast, by using low and high radiation energy beams respectively. A high-energy tomosynthesis process of volume portion is performed with high total radiation energy beam higher than low energy beam. Two dimensional low-energy image is subtracted from two dimensional high-energy image to visualize the concentration of contrast agent. Independent claims are included for the following: (1) tomosynthesis device; (2) computer program product for representing concentration of contrast agent in predetermined volume portion of female breast; and (3) electronically readable data carrier storing electronically readable control information for representing concentration of contrast agent in predetermined volume portion of female breast.
