FIG. 6.

Demonstration of the chest wall effect in the proposed library-based scatter correction. (A) Comparison of patient images without correction (first row), corrected using the library-based method without and with the inclusion of the chest wall in the MC simulation (second and the third row, respectively), and the difference between the two correction schemes (fourth row). Columns (a) and (b): Coronal and sagittal views for an average size breast with Deff of 14 cm. Columns (c) and (d): for a large size breast with Deff of 18 cm. Display window: [0.2 0.3] cm−1 for the first three rows, [−0.01 0.01] cm−1 for the last row. The dashed lines in the first row indicate where the 1D profiles of Fig. 7 are taken. (B) Comparison of scatter corrected images near chest wall. Top row shows the results for an average breast size of 14 cm and bottom row for a large breast size of 18 cm. The display windows for uncorrected/corrected images and difference images are the same as those in (A).
