A new framework enables the development of computer-aided detection (CADe) systems using only training data characteristics. This approach successfully created CADe systems for brain aneurysms and lung nodules, demonstrating its feasibility.

Area of Science:

  • Medical imaging analysis
  • Artificial intelligence in healthcare
  • Computer-aided detection systems

Background:

  • Developing computer-aided detection (CADe) systems often requires lesion-specific algorithm design.
  • A generalized framework could streamline CADe system development by relying on training data properties.

Purpose of the Study:

  • To demonstrate the feasibility of a generalized framework for developing CADe systems.
  • To create CADe systems without the need for lesion-specific algorithm design.

Main Methods:

  • A prototype framework was used to develop two distinct CADe systems.
  • Four pretrained algorithms for preprocessing, candidate extraction, detection, and classification were sequentially trained.
  • Two datasets were utilized: brain MRA with cerebral aneurysms and chest CT with lung nodules.
