Area of Science:

  • Medical Imaging and Artificial Intelligence
  • Neuro-oncology and Computational Pathology

Background:

  • Manual brain tumor diagnosis from CT/MRI scans is time-consuming.
  • Conventional object detection models struggle with medical image complexities like noise and blurred boundaries.
  • Deep learning offers potential for automated brain tumor detection and classification.

Purpose of the Study:

  • To investigate deep learning's impact on brain tumor detection accuracy and efficiency.
  • To analyze the influence of model parameters, batch size, and anchor boxes on detection performance.
  • To develop and evaluate an optimized deep learning model for improved brain tumor detection.

Main Methods:

  • Investigated the effects of model parameters, batch size, and anchor boxes on detection performance.
  • Developed a novel backbone network using RepConv and RepC3 with an FGConcat feature map splicing module.
  • Introduced the RepConv-RepC3-FGConcat Network (RRFNet) for brain tumor detection.

Main Results:

  • Excessive parameters or anchor boxes can decrease detection accuracy; more data improves performance.
  • RRFNet effectively learns tumor semantics while maintaining low inference parameters for speed.
  • RRFNet achieved a 79.2% mAP, surpassing YOLOv8 in brain tumor detection accuracy.

Conclusions:

  • The RRFNet model enhances both the accuracy and efficiency of brain tumor detection.
  • Optimized deep learning approaches are crucial for time-sensitive and precise clinical applications.
  • RRFNet demonstrates significant potential for improving automated diagnostic tools in neuro-oncology.
