Abstract :
Due to accurate 3D information, minimal radiation dose, and low machine cost, cone-beam computed tomography (CBCT) has become increasingly popular in dental and maxillofacial imaging. In this paper, we propose the first development of the CBCT scanner in Thailand, called DentiiScan. The gantry system uses a cone-beam X-ray source and a large amorphous silicon flat panel detector to rotate around a patient´s head and capture raw data. Our reconstructed algorithm based on GPU calculation can produce 3D image data in approximately 5 seconds. Image quality of reconstructed images was evaluated through a standard phantom as well as visual analysis on real clinical data. The results show that our system is suitable for diagnosis and treatment planning in dental and maxillofacial applications.
