    Diagnosis of Periodontitis with the Energy Information in Dental Panoramic Image

    In dental panoramic imaging the teeth and jaws are imaged with x-rays. And in this imaging, energy of photons is acquired with the integral manner and thus we cannot use the information of x-ray energy passing...

    Quantitative Measurement of Physical Value of Materials with a Dental Panoramic Radiograph

    In dental panoramic images the information on physical change of organs such as the alveolar bone and jaw bones is very important to diagnose several diseases. The tomosynthesis approach can focus on a specifi...

    Advantages of Energy-Binned Photon Counting Detector

    We developed an energy-binned photon counting (EBPC) detector with a CdTe crystal, in which we can measure photons with four energy windows. The data acquired with the detector have information about the energ...
