ACCOUNTING FOR FOREIGN OBJECTS WHEN CREATING CT-BASED ATTENUATION MAPS |
摘要 |
In a method for generating an attenuation map (30), image elements of a reconstructed tomographic image (24) are segmented into at least first, second, and third classes (50, 52, 54). Each image element of the first class (50) is transformed using a first image element value-dependent attenuation transform (60). Each image element of the second class (52) is transformed using a second image element value-dependent attenuation transform (62) different from the first image element value-dependent attenuation transform. Each image element of the third class (54) is transformed using a third image element value-dependent attenuation transform (64) different from both the first and second image element value-dependent attenuation transforms. |
