    Panasonic Developing Swept Source Optical Coherence Tomography System for Dental Applications

    Panasonic Shikoku Electronics Co., Ltd. is developing an Swept Source OCT system designed for dental purposes, in collaboration with researchers led by Prof. Yasunori Sumi form National Center for Geriatrics and Gerontology, Japan and Prof. Junji Tagami, Global COE, Tokyo Medical and Dental University.

    According to the information that the group disclosed at the recent general meeting of the International Association for Dental Research in Barcelona, Spain, the Proto Type system is based on Swept Source Optical Coherence Tomography with a high-speed frequency swept external cavity laser as the light source at a center wave length of around 1330nm with a waveband of over 100nm and sweep rate of 30 kHz. The system can provide 2D and 3D images of the dental structure intra-orally, with lateral and axial optical resolution of 20µm and 12µm, respectively.

    The hand-held intraoral probe has been specifically designed for dental use. The intraoral probe is equipped with a CCD camera that enables photographic visualization of the surface being scanned in real-time. The probe power is less than 10mW, within the American National Standards Institute safety standard.
