This document discusses the benefits of tomographic ultrasound imaging (TUI) or sono-CT for medical imaging. TUI allows acquiring orthogonal slices such as sagittal, coronal, and axial slices through a volume of data. This provides better assessment than standard ultrasound alone. Examples shown include visualizing the full extent of liver abscesses, gallbladder neck anatomy, and intrauterine abnormalities using TUI sagittal slices.

IMAGING
1. TUI ( Parallel slices) / SONO CT .
2. This method of visualization is
consistent with other medical systems
such as CT /MRI.
3. It is a visualization mode for 3D , 4D
data sets.
4. Orthogonal slices ( sagittal / coronal /
axial ) can be acquired through the
acquired volume data and better
assessment can be done.
