Area of Science:

• Medical Physics
• Computational Modeling
• Medical Imaging

Background:

• Boundary-representation (B-Rep) computational phantoms (CPs) offer high anatomical accuracy and flexibility for dosimetry and medical imaging simulations.
• However, their complexity and lack of native support in Monte Carlo (MC) transport codes hinder their widespread adoption.

Purpose of the Study:

• To develop a user-friendly software platform, the Interactive Posture Program (IPP), to simplify the creation and utilization of B-Rep CPs in MC simulations.
• To enhance accessibility of advanced B-Rep phantom technology for researchers in medical physics and related fields.

Main Methods:

• Developed the Interactive Posture Program (IPP) with a real-time 3D graphical interface for easy phantom customization and scenario creation.
• Integrated morphing tools for diverse anatomical variations using the realistic anthropomorphic flexible (RAF) phantom family.
• Implemented automatic generation of MC-compatible input files for seamless integration with standard particle transport codes.

Main Results:

• The IPP enables intuitive creation of individualized phantoms and realistic exposure scenarios.
• Users can extensively customize anthropomorphic phantoms to simulate various anatomical differences.
• The software automatically generates compatible input files for widely used MC transport codes, significantly reducing setup complexity.

Conclusions:

• The IPP effectively addresses the challenges associated with using B-Rep computational phantoms in MC simulations.
• This platform democratizes the use of high-fidelity B-Rep phantoms, facilitating more accurate and personalized dosimetry and medical imaging research.
