Cone Beam CT provides clinicians with three dimension views of patient’s head and neck area at relatively low radiation dose compared with medical CT. There are different steps involved in obtaining the final image volume. It is important to understand the underlying principles of action for Cone Beam CT in order to obtain the best image quality while lowering the radiation dose to the patient.
In this part 1 review article published at the American Journal of Neuroradiology, Miracle and Mukherji go over Cone Beam CT physical principles. They explain image acquisition, data reconstruction and different algorithms used to generate the final image.
