Summary
A new optomechatronic system uses 3D reconstruction and diffuse optical mammography (DOM) to detect breast cancer abnormalities. This technology aids in earlier diagnosis and precise tumor localization for improved treatment planning.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Oncology
Background:
- Development of an optomechatronic system for 3D breast tissue imaging.
- Focus on identifying abnormalities to aid breast cancer diagnosis.
Purpose of the Study:
- To present the initial testing of a novel system for breast cancer detection.
- To combine 3D reconstruction with diffuse optical mammography (DOM) for enhanced diagnostic capabilities.
Main Methods:
- Integration of 3D reconstruction technology with diffuse optical mammography (DOM).
- DOM analyzes tissue optical properties to detect density and composition variations.
- 3D reconstruction provides detailed visualization for tumor localization and sizing.
Main Results:
- Successfully identified simulated abnormalities (10, 15, 20 mm) in breast tissue phantoms.
- Demonstrated feasibility using Chinese ink as a contrast agent for simulated lesions.
Conclusions:
- The system generates 3D images via data processing algorithms, offering a non-invasive detection method.
- Pilot testing with phantoms is underway to evaluate accuracy and functionality before clinical trials.

Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
