Oral and maxillofacial Radiology, Videofluoroscopic study, Videoendoscopic study, Dysphagia, Screening, Osteoporosis, MRONJ(BRONJ), Radiation therapy and Interstitial brachytherapy for oral cancer

【Recent highlights】
We are conducting clinical applications by integrating an automatic diagnostic function into panoramic X-ray imaging systems for the early detection of osteoporosis. In the field of dysphagia, we are planning to apply “enzyme infusion (freeze–thaw impregnation method)” to develop soft foods for caregiving. For brachytherapy in oral cancer, we have achieved improved treatment outcomes through the use of ultrasound imaging. We are also engaged in research on AI-based diagnostic imaging in dentistry and the head and neck region.

【Education】
Oran and maxillofacial radiology is the study of the core principles of image production, including advanced imaging such as Computed tomography (CT), Cone-beam CT (CBCT), Magnetic resonance imaging (MRI), and Ultrasonography (US), basic science of radiation and radiotherapy; and as importantly how to interpret the medical imaging findings.
