We developed real-time animations to visualize treatment effects on organ lesions over time. This visual tool aids in understanding treatment efficacy for medical education and patient decision-making.

Area of Science:

  • Medical Visualization
  • Computational Anatomy
  • Radiology

Background:

  • Assessing treatment efficacy often relies on observing changes in medical imaging over time.
  • Visualizing these changes dynamically can enhance understanding for both clinicians and patients.
  • Current methods may lack real-time, intuitive representations of treatment-induced anatomical evolution.

Purpose of the Study:

  • To develop and implement a real-time animation method for visualizing the temporal evolution of organ lesions during treatment.
  • To create a "morph" animation that illustrates the transformation from pre-treatment to post-treatment shapes.
  • To leverage graphics processing units (GPUs) for efficient volume visualization and morph generation.

Main Methods:

  • Utilized graphics processing units (GPUs) for real-time computation.

  • Developed a metamorphosis (morph) technique to show shape changes over time.
  • Applied the method to visualize changes in a patient's liver affected by lymphoma undergoing chemotherapy.

    • Main Results:

    • Successfully generated real-time animations depicting lesion evolution.
    • Demonstrated the method's capability in visualizing treatment response in a clinical case.
    • Achieved efficient visualization and morph generation using GPU acceleration.

    Conclusions:

    • Real-time animation of lesion evolution is a powerful tool for assessing treatment efficacy.
    • This visualization technique can significantly benefit medical education and patient comprehension.
    • The GPU-accelerated morphing method offers an efficient approach to dynamic medical image analysis.
