Computer-assisted surgery offers personalized treatment but requires extensive medical image analysis. This study addresses interactive segmentation challenges to improve usability and reduce manual intervention in surgical planning.

Area of Science:

  • Medical imaging
  • Computer-assisted surgery
  • Surgical planning

Background:

  • Computer-assisted surgery (CAS) enables patient-specific treatments, reducing surgical risks and recovery times.
  • Current CAS applications in fields like cardiac and craniofacial surgery are limited to complex cases due to high implementation effort.
  • Extensive medical image analysis, particularly tissue classification (segmentation), is a major bottleneck in surgical planning, often requiring significant manual input.

Purpose of the Study:

  • To identify and address the major problems associated with interactive image segmentation in surgical planning.
  • To explore usability aspects that have been overlooked in traditional computational segmentation research.
  • To propose consequences and solutions for improving the segmentation process in computer-assisted surgery.

Main Methods:

  • Focus on the challenges and limitations of current interactive segmentation techniques.
  • Analysis of the manual intervention required in medical image classification.
  • Review of research focusing on computational aspects versus usability in segmentation.

Main Results:

  • Interactive segmentation in surgical planning is hampered by significant usability issues.
  • The high manual effort in tissue classification limits the broader adoption of CAS.
  • Existing research has predominantly focused on computational algorithms, neglecting user interaction.

Conclusions:

  • Improving the usability of interactive segmentation is crucial for advancing computer-assisted surgery.
  • Addressing the manual intervention bottleneck can enhance the efficiency of surgical planning.
  • Future research should integrate computational methods with user-centered design for more effective CAS tools.
