Area of Science:

  • Medical Imaging
  • Artificial Intelligence in Medicine
  • Neuroscience

Background:

  • Computed Tomography (CT) is crucial for stroke classification, penumbra quantification, and radiomics.
  • Acquiring standard, accurate, and repeatable follow-up images in CT is challenging.
  • An intelligent CT system was developed to address these limitations in stroke evaluation.

Purpose of the Study:

  • To develop an intelligent CT system for improved stroke evaluation during follow-up.
  • To enhance the accuracy, repeatability, and standardization of CT imaging in stroke patients.
  • To support stroke-relevant radiomics and neuroscience research.

Main Methods:

  • A region proposal network (RPN) was trained on 76,382 human faces for facial detection.
  • V-Net was used to segment two regions of interest (ROIs) from 295 subjects.
  • Scanning couch movement was calculated using a calibration table, with validation on 1,124 patients.

Main Results:

  • The developed system, CAPITAL-CT, achieved high accuracy in facial detection (98.7% success rate) and segmentation (within 3 mm distance error).
  • Real-time, accurate, and repeatable automatic scanning was accomplished.
  • The system demonstrated a lower radiation exposure dose compared to conventional methods.

Conclusions:

  • CAPITAL-CT generates standard and reproducible images, simplifying radiologist workflow.
  • The system significantly aids in the follow-up of stroke patients.
  • This technology offers substantial benefits for multifield neuroscience research.
