摘要：
An intraoral cone-beam computed tomographic scanner is disclosed. A frame body of the intraoral cone-beam computed tomographic scanner includes a central axis and a light source seat. The light source seat moves along a scanning path and rotated around the central axis. An image capturing module is disposed on the light source seat and reciprocated along the scanning path. The image capturing module is configurated to generate a light beam emitted from outside to the patients mouth. A photosensitive sheet or member is positioned in the patients mouth. The light beam moves in the scanning path corresponding to the photosensitive sheet, so that the image capturing module can generate seires two-dimensional images. An image processing module receives the two-dimensional images and calculates the two-dimensional images to generate a three-dimensional image. Therefore, the two-dimensional images can be captured by moving positions of the image capturing module, and then calculating two-dimensional images to generate the three-dimensional images, thereby achieving dental diagnosis with high-resolution and lower radiation dose.本發明提供一種口內電腦斷層掃描器及其操控方法,其中口內電腦斷層掃描器之架體包含中心軸與光源座,光源座具有掃描路徑,此掃描路徑以中心軸為旋轉中心。攝像光源模組則設於光源座且沿掃描路徑往復位移,且攝像光源模組可產生光束並由外側照射至患者口腔。感光片定位於患者口腔內,光束對應感光片位移掃描,藉以令攝像光源模組攝影產生系列之二維光片影像。影像處理模組接收並運用系列二維光片影像以組成三維影像。藉此,透過移動攝像光源模組的位置來進行二維光片影像攝影,進而運算組成三維影像,以實現高解析度且低劑量的牙科診斷。200‧‧‧架體210‧‧‧架座212‧‧‧軌道220‧‧‧位移件222‧‧‧擺臂軌道224a‧‧‧第一連動部224b‧‧‧第二連動部224c‧‧‧第三連動部226‧‧‧感光片固定座230‧‧‧電動旋轉盤240‧‧‧中心軸250‧‧‧光源座252‧‧‧旋轉擺臂2522‧‧‧支架移動軌道254‧‧‧模組支架2542‧‧‧模組移動軌道256‧‧‧轉動軸300‧‧‧攝像光源模組310‧‧‧X光管400‧‧‧感光片
