Quantitative evaluation and feasibility analysis of cone-beam computed tomography (CBCT) image quality based on three-dimensional parameters / 中华放射肿瘤学杂志

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 threedimensional 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.
