This study visualizes chemotherapy drug flow during chemoembolization to train hand-eye coordination. The method uses simulated particle trails on fluoroscopic images for better procedural understanding.

Area of Science:

  • Medical Imaging
  • Surgical Simulation
  • Interventional Radiology

Background:

  • Chemoembolization involves injecting chemotherapy drugs and emboli directly into tumors via catheter.
  • A significant risk is incorrect embolus lodging, potentially compromising normal tissue blood supply.
  • Effective training is crucial for improving hand-eye coordination during these procedures.

Purpose of the Study:

  • To develop a visualization model for chemotherapy drug flow during chemoembolization.
  • To enhance training tools for hand-eye coordination in interventional procedures.
  • To simulate particle flow within the hepatic vascular system from a catheter tip.

Main Methods:

  • Constructing a vascular model using sweeping and blending operations.
