Which imaging modality uses tomographic techniques to produce cross-sectional slices through tissue?

• A. 3D imaging
• B. Tomographic ultrasound imaging
• C. Compound imaging
• D. Tissue harmonic imaging

Answer: (B)

Tomographic approaches build a cross-section by combining information acquired from multiple angles. Tomographic ultrasound imaging uses this idea: it collects ultrasound data from different angles and reconstructs thin slices of tissue, producing true cross-sectional views. This is what sets it apart from other ultrasound advances. 3D imaging compiles data to form a volume, but it isn’t inherently reconstructing cross-sections from multiple angles the way tomography does. Compound imaging and tissue harmonic imaging improve resolution and image quality within a single plane, rather than creating tomographic slices.
