Abstract: Cone-beam computed tomography (CBCT) image based on a single layer of image and the choice of regions of interest (ROI) is affected by individual subjectivity, making it difficult to compare the image quality. In this article, a quantitative evaluation method of CBCT image quality based on three-dimensional parameters was proposed, which was extended from single layer to multi-layer and from pixel to voxel. The selection range of ROI was discussed to reduce the error of artificial selection and realize the quantitative evaluation of image quality by three-dimensional parameters.
