A computer-aided hepatocellular carcinoma system is introduced in this paper. Tumor size and tumor intensity changes are heavily referenced in clinical practice while diagnosing hepatocellular carcinoma. In the enhancement scanning, the tumor might have different intensity appearance in three consecutive phases: arterial phase, portal vein phase and delay phase. By comparing the intensity of tumor...
Texture is one of the important characteristics used in identifying objects or regions of interest in an image. This paper describes some textural features based on integrated spatial gray level co-occurrence matrix, and illustrates the effectiveness of four textural features in categorizing ultrasound breast tumor images by means of Fuzzy C-means and K-medoid clustering algorithms respectively. The...
The objective of this paper is to find out which is the best to calculate the volume of the sample using the virtual organ computer-aided analysis (VOCALtrade II) software. There are fifteen small eggs called "samples" assumed as breast tumors which real volumes are provided by the doctor of Huaxi hospital. The VOCALtrade II software provides three modes of sample's contour generation: Manual...
