Methods and apparatus for tumor diagnosis

Method for tumor extraction comprising the process of:

• process for operating index of uneven complexity of the surface roughness which expresses arithmetic volume distribution which concerning tumor regions, normal tissues and tumor boundary between said tumor regions and normal tissues on a ultrasonic echographic image of each three dimensional voxels as probability distribution in [0,1] region of membership function which is employed a fuzzy reasoning;
• process for generating membership function includes process for extracting automatically said tumor region by arranging said arithmetic volume distribution according to fuzzy reasoning which employs said membership function;
• fuzzy reasoning process for classifying said each voxels into predetermined plural of types of region according to said generated membership function and fuzzy rules thereof;
• process for carrying out defuzzify process to said each voxels according to a relaxation technique, followed by;
• defuzzifying process for finally determining tumor region by classifying “tumor”, “normal tissue” or “boundary”;
• and said fuzzy reasoning process includes a process to determine a likeness of said voxel as “tumor”, “normal tissue” or “boundary” and to classify said voxel corresponding to said degree.
