Malignant liver cancer ultrasonic image processing and analysis based on MATLAB / 中国组织工程研究

ABSTRACT

MATLAB Image Processing Toolbox (IPT) was used to analyze the filtered images and draw the gray value contrast curve respectively between cancerous and normal regions of liver tissue,and also detect the edge of the cancerous tissue region. Cancerous and normal region of 30 subjects were assessed with gray value curve. The change of cancerous region was significantly higher than the normal one. The gray value curve can effectively quantify the gray information of the image. Quantitative image parameters have an important reference value on the clinical diagnosis of liver cancer.
