I am unable to visualise 3D of bone. I have chosen CTAA2 and the soft tissue us covering up the bone as shown in right upper panel.  
Please advice.

Use CT-Bones preset instead.

You can adjust the Shift slider left and right until you see what you want.

May I have an urgent help?

I loaded the DICOM files and I have changed the setting to CT bone and adjusted the slicer to get the bone visualization. My main focus is on the cervical bone. **However, the soft tissues around the cervical bone is still visible (as shown below). If I pull the slicer too far, part of the bone is lost.**

Please help me. I need a good visualization as I need to do segmentation.

You can open the Advanced settings and adjust the transparency and color ranges. You could use the Segment Editor too and just segment the bone.
