Phase Contrast and Differential Interference Contrast Microscopy

12.1K
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

    Area of Science:

    • Artificial Intelligence in Medicine
    • Medical Imaging Analysis
    • Radiology

    Background:

    • Artificial intelligence (AI) integration is transforming medicine, particularly in radiology.
    • Vision foundation models show promise for radiologic imaging analysis.
    • Existing models pretrained on general images struggle with the complexity of 2D and 3D radiologic data.

    Purpose of the Study:

    • To introduce RadCLIP (radiologic contrastive language-image pretraining), a novel cross-modal vision-language foundational model.
    • To address the limitations of general-purpose models in analyzing complex radiologic data.
    • To enhance diagnostic precision and efficiency in radiologic imaging analysis.

    Main Methods:

    • Developed RadCLIP based on the contrastive language-image pretraining (CLIP) approach.
    • Incorporated a slice pooling mechanism for volumetric (3D) image analysis.
    • Pretrained RadCLIP on a large, diverse dataset of 2D/3D radiologic image-text pairs.

    Main Results:

    • RadCLIP effectively aligns radiologic images with corresponding text annotations.
    • Demonstrated superior performance in unimodal radiologic image classification.
    • Showcased strong capabilities in cross-modal image-text matching.

    Conclusions:

    • RadCLIP offers a robust vision backbone for radiologic imaging.
    • The model shows significant promise for improving diagnostic accuracy and efficiency in clinical radiology.
    • Key contributions include dataset curation, model pretraining, and adapter development for 2D/3D data integration.
