[Two-Dimensional Electron Beam Radiotherapy Planning System with Modeling Function]

Area of Science:

• Medical Physics
• Radiation Oncology
• Software Development

Background:

• Two-dimensional electron beam radiotherapy requires custom lead blocks for precise targeting and normal tissue sparing.
• Current treatment planning systems, like Pinnacle, lack automated lead block shaping, necessitating manual adjustments by physicists.
• This manual process is inefficient, especially for repeated treatment plans, hindering overall design efficiency.

Purpose of the Study:

• To develop an automated system for designing 2D electron beam radiotherapy plans.
• To enhance the efficiency of treatment planning by reducing manual lead block adjustments.
• To create a user-friendly interface for physicists to quickly design radiotherapy plans.

Main Methods:

• Independent development of a 2D electron beam radiotherapy planning system using Qt Creator.
• Implementation of automated lead block shaping capabilities within the system.
• Integration of features to quickly set and recalculate field parameters for dose calculation.

Main Results:

• The developed system successfully automates the shaping of lead blocks to match desired beam fields.
• Significant reduction in the time and effort required for designing 2D electron beam radiotherapy plans.
• Elimination of repetitive manual adjustments for physicists, leading to improved workflow.

Conclusions:

• The new Qt Creator-based system offers a substantial improvement in the efficiency of 2D electron beam radiotherapy planning.
• Automation of lead block design streamlines the workflow for radiation oncology physicists.
• This advancement contributes to faster and more accurate radiotherapy treatment design.
