Computed Tomography01:10

Computed Tomography

6.3K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Biological Samples with Optical Microscopy

5.4K
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.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

    Area of Science:

    • Medical Imaging
    • Dermatology
    • Computer Vision

    Background:

    • Total Body Photography (TBP) is crucial for skin cancer screening in high-risk patients.
    • Current TBP systems require enhancement in automatic lesion detection and analysis.
    • Image resolution and sharpness are key limitations in existing TBP systems.

    Purpose of the Study:

    • To propose a novel shape-aware TBP system for high-fidelity full-body image capture.
    • To optimize image quality, specifically resolution and sharpness, across the entire body surface.
    • To improve automated analysis of skin lesions for enhanced skin cancer screening.

    Main Methods:

    • A shape-aware TBP system utilizing depth and RGB cameras on a 360-degree rotary beam.
    • 3D body shape estimation to guide focus optimization.
    • An in-focus surface optimization method to determine optimal focus distance per camera pose.
    • Evaluation using simulation data and a real mannequin scan.

    Main Results:

    • The system achieves high resolution (0.068 mm/pixel and 0.0566 mm/pixel).
    • Approximately 85-95% of the body surface area is captured in-focus.
    • The shape-aware focus method surpasses traditional auto-focus protocols.
    • Demonstrated effectiveness in capturing high-fidelity body images.

    Conclusions:

    • The proposed shape-aware TBP system significantly enhances image quality for full-body imaging.
    • High-fidelity imaging is critical for advancing automated skin lesion analysis in cancer screening.
    • This technology holds promise for improving early detection and management of skin cancer.
