The titanium content in the Variscan (late Paleozoic) Kalba granite batholith in eastern Kazakhstan, USSR, exhibits a regular variation relative to the various intrusive phases, decreasing from 0.80 percent TiO (sub 2) in the oldest phase (porphyritic biotite granite) to 0.02 percent TiO (sub 2) in the youngest phase (pegmatites). Biotite and ilmenite are the host minerals of titanium. The average TiO (sub 2) content of the most widely developed granite facies, and the least contaminated by assimilation of titanium-rich shales, is 0.33 percent. (An editor's note, by Jack Green, relative to the high capacity of biotite for Ti is appended.).

Cone-beam CT (CBCT) has become the standard image guidance tool for patient setup in image-guided radiation therapy. However, due to its large illumination field, scattered photons severely degrade its image quality. While kernel-based scatter cor...
