This study introduces a real-time, interactive 3D segmentation pipeline for medical imaging. The user-friendly system provides rapid, accurate segmentation of anatomical structures, benefiting clinical applications.

Area of Science:

  • Medical imaging analysis
  • Computational anatomy
  • Image processing

Background:

  • Accurate segmentation of medical images is crucial for diagnosis and treatment planning.
  • Existing methods can be time-consuming and require specialized expertise.

Purpose of the Study:

  • To develop and evaluate a real-time, interactive 3D segmentation pipeline.
  • To provide a user-friendly interface for medical image segmentation.
  • To demonstrate the system's application in clinical cases.

Main Methods:

  • Implementation of low-level segmentation operations on a massively parallel computer.
  • Development of a graphical user interface using public domain software.
  • Application of the pipeline to approximately 300 computed tomographic (CT) and magnetic resonance imaging (MRI) datasets.

Main Results:

  • The processing pipeline executes in seconds with a short interactive response time.
  • Segmentation of multiple organs (bones, aorta, kidneys, brain, skin) was achieved in minutes.
  • Demonstrated successful application in two typical clinical cases.

Conclusions:

  • The real-time interactive 3D segmentation system yields satisfactory results in a short time.
  • The system is easily learned by non-specialized users with medical backgrounds.
  • Facilitates efficient and accessible medical image segmentation.
