Area of Science:

  • Medical Imaging and Image Analysis
  • Computer-Aided Surgery
  • Radiology

Background:

  • Pre-operative donor evaluation in living donor liver transplantation presents significant challenges.
  • Precise liver volume measurement and 3D rendering are essential for surgical planning.
  • Computer-aided systems can aid in accurate segmentation and visualization.

Purpose of the Study:

  • To evaluate the performance of two Insight Toolkit (ITK) algorithms for liver segmentation from CTA datasets.
  • To assess the suitability of ITK/VTK pipelines for pre-surgical planning in liver transplantation.

Main Methods:

  • Utilized the Insight Toolkit (ITK) for liver segmentation from computed tomography angiography (CTA) data.
  • Employed two distinct ITK algorithms for quantitative and qualitative performance evaluation.
  • Combined ITK segmentation results with Visualization Toolkit (VTK) for 3D rendering.

Main Results:

  • Presented quantitative and qualitative performance metrics for the selected ITK segmentation algorithms.
  • Demonstrated the effectiveness of ITK algorithms in achieving precise liver volume measurements.
  • Highlighted the utility of ITK/VTK pipelines for generating informative 3D visualizations.

Conclusions:

  • ITK provides effective and computationally efficient algorithms for liver segmentation.
  • ITK/VTK pipelines are valuable tools for pre-surgical assessment in liver transplantation.
  • The evaluated ITK algorithms show promise for improving donor evaluation processes.
