Method for scattered radiation correction |
摘要 |
For scattered radiation correction in dual X-ray absorptiometry it is proposed to use the additional information supplied by the attenuation images in different energy ranges in a correction image area with homogeneous attenuation coefficients in order to determine the respective scattered radiation fraction. Toward that end, the inverse of the primary radiation function is considered and a search conducted for that scatter-to-primary ratio which leads to consistent mass per unit areas for the attenuation images recorded in different energy ranges.
