  • Publication number: 20260215728
    Abstract: A non-invasive imaging system and method for visualizing cranial sutures through overlying tissue are disclosed. The system includes a near-infrared and/or short-wave infrared illumination source, an imaging device that detects reflected short-wave infrared radiation, a linear polarizer, and a long-pass filter arranged in an optical path between a cranial region and the imaging device. The linear polarizer reduces surface-reflected light, and the long-pass filter attenuates wavelengths below a selected cutoff wavelength while passing short-wave infrared light reflected from beneath overlying tissue. Detected short-wave infrared radiation is provided to processing circuitry that generates image data representing cranial suture morphology. The disclosed approach enables evaluation of cranial sutures in the absence of ionizing radiation.

  • Publication number: 20190119750
    Abstract: The present disclosure relates to a method for discovering effective bioactive compounds, based on plant developmental biology, and aims to discover a lead bioactive compound for new drugs by repeating screening based on phenotypes of a plant as a marker on the basis of plant developmental biology. To this end, the present disclosure provides a method for discovering effective bioactive compounds, and includes screening candidates for developing a new drug by using unique phenotypes as a marker shown by a plant when it is grown with a specific material.
