Researchers developed Digital Image Processing (DIP) software to streamline computational dosimetry. This tool integrates essential image processing tasks for creating anthropomorphic phantoms from CT/MRI scans, aiding research in numerical dosimetry.
Area of Science:
- Medical Physics
- Image Processing
- Computational Science
Background:
- Anthropomorphic phantoms for computational dosimetry are crucial for accurate radiation dose calculations.
- Constructing these phantoms from medical imaging (CT/MRI) requires complex image processing, often lacking in single software solutions.
- Existing software limitations hinder research progress in numerical dosimetry.
Purpose of the Study:
- To present the second version of the Digital Image Processing (DIP) software.
- To provide an integrated solution for image processing tasks required in computational dosimetry.
- To support the development of anthropomorphic phantoms for numerical dosimetry research.
Main Methods:
- Development of the Digital Image Processing (DIP) software, featuring enhanced menu organization and segmentation capabilities.
- Integration of functionalities for image format transformation, 2D to 3D matrix conversion, sampling, quantization, enhancement, restoration, and segmentation.
- Support for reading, editing, and writing 3D image matrices from axial scans, with output options for JPEG and SGI (Simulações Gráficas Interativas) files.
Main Results:
- The DIP software version 2 offers a more formalized menu structure and a dedicated digital image segmentation menu.
- The software successfully integrates multiple image processing steps necessary for voxel phantom construction.
- DIP facilitates the handling of various image formats and the creation of 3D volumetric data for dosimetry simulations.
Conclusions:
- The enhanced DIP software addresses the need for an integrated tool in computational dosimetry.
- It streamlines the process of creating anthropomorphic phantoms, accelerating research in numerical dosimetry.
- The software's capabilities support the development of advanced exposure computational models.
