This study presents a novel method for semi-automatic 3D liver segmentation and classification using CT scans on mobile devices, improving surgical planning for hepatectomies.

Area of Science:

  • Medical Imaging
  • Surgical Planning
  • Computational Anatomy

Background:

  • Hepatectomies require precise liver segmentation from medical images.
  • Current slice-by-slice analysis of CT datasets is time-consuming and inefficient.
  • Accurate estimation of remaining liver volume is crucial for surgical success.

Purpose of the Study:

  • To develop an efficient, semi-automatic 3D segmentation and classification strategy for patient-specific liver models.
  • To enable accurate functional remaining liver volume estimation using mobile display devices.
  • To streamline the analysis of CT datasets for hepatectomy planning.

Main Methods:

  • Utilized volume visualization of standard CT datasets.
  • Implemented a semi-automatic segmentation and classification approach.
