摘要: Although x-ray mammography is widely developed for breast tumour detection, it suffers from spatial superposition in its two-dimensional (2D) representation of a three-dimensional (3D) structure. Accordingly, 3D imaging, such as cone-beam computed tomography (CT), arises at the historic moment. In this paper, we theoretically elucidate effect associated with on detection. This explanation based line integral traversing composite model. As result, can characterize difficulty detecting small tumours terms local intensity contrast images. comparison, also introduce CT imaging volume representation, which offers advantages mass segmentation and measurement. The discussion demonstrated an experiment surgical specimen. conclusion, strongly believe that volumetric allows more accurate
