[Three-dimensional longitudinal dissection view of hollow viscus]

Area of Science:

• Medical Imaging
• Radiology
• Anatomical Visualization

Background:

• Visualizing hollow viscus pathologies and their spatial extent is crucial for diagnosis and treatment planning.
• Current methods may have limitations in providing comprehensive three-dimensional insights into internal organ structures and disease progression.

Purpose of the Study:

• To develop and evaluate a novel three-dimensional (3D) visualization technique for pathologies of hollow viscera.
• To improve the perception of internal morphology and disease extension using computed tomography (CT) data.

Main Methods:

• Acquisition of volume data for larynx, trachea, stomach, rectum, and urinary bladder using helical CT with moderately thin slices.
• Creation of simulated longitudinal surgical cut sections to display interior morphology alongside pathology.
• Generation of a cylindrical projection profile by incising and unfolding a longitudinal wall to reveal the interior.

Main Results:

• The 3D visualization effectively displayed pathologies and their extension within hollow viscera.
• Simulated surgical cuts and cylindrical projection provided enhanced visualization of interior morphology.
• The combined 3D profile and cylindrical projection views offered superior perception compared to existing methods.

Conclusions:

• The developed helical CT-based 3D visualization technique offers significant advantages for assessing hollow viscus pathologies.
• This method enhances the understanding of disease extension and internal anatomical details.
• The technique provides improved visual perception, potentially aiding in surgical planning and diagnostic accuracy.
