Area of Science:

  • Medical Imaging
  • Oncology
  • Computer Science

Background:

  • Hepatocellular Carcinoma (HCC) is a prevalent liver cancer often linked to cirrhosis caused by viral hepatitis (Hepatitis B Virus [HBV], Hepatitis C Virus [HBC]) or alcoholism.
  • Even without cirrhosis, viral hepatitis infections increase liver cancer risk.
  • Computed Tomography (CT) excels at defining liver tumor borders, but 3D reconstruction can be computationally intensive, time-consuming, and costly. Low contrast in CT slices challenges accurate tumor characterization.

Purpose of the Study:

  • To develop an automated framework for accurate liver tumor characterization and localization in CT datasets.
  • To improve the visualization and analysis of Hepatocellular Carcinoma (HCC) by overcoming limitations of existing CT imaging techniques.
  • To enhance medical diagnosis and therapy planning for HCC patients.

Main Methods:

  • Extension of the SurLens Visualization System with an automatic liver tumor localization technique.
  • Utilization of Compute Unified Device Architecture (CUDA) for high-performance computation.
  • Evaluation using liver CT datasets from the Imaging Science and Information Systems (ISIS) Center at Georgetown University Medical Center.

Main Results:

  • Successful visualization of liver CT datasets and localization of tumors without requiring prior segmentation.
  • Achieved significantly improved processing speed and reduced costs compared to traditional methods.
  • Enabled immediate reconstruction of datasets and mapping of tumor tissues within the surrounding liver parenchyma.

Conclusions:

  • The proposed framework offers an efficient and cost-effective solution for Hepatocellular Carcinoma (HCC) analysis using CT data.
  • Automated tumor localization and visualization without segmentation represent a significant advancement in HCC diagnosis and treatment planning.
  • The system's speed and accuracy hold promise for widespread clinical application in liver cancer management.
