The goal of this research is to develop ′breast ultrasound computer aided diagnosis (CAD) system for the early diagnosis and decision support for breast. The final goal is to develop decision support system to provide the radiologists with the ability to better differentiate 80％ benign lesions from 20％ solid lesions that may be suggestive of cancer. To achieve this goal, the following researches were carried out.
- Construct breast ultrasound database
- Development of preprocessing algorithm to enhance the breast ultrasound image.
- Development of texture parameters to differentiate benign lesions from malignant ones.
- Development of mass boundary detection algorithm.
- Development of shape parameters to differentiate benign lesions from malignant ones.
- Study of decision support system based on texture and shape parameters.
- Development of unified system based on ‘window platform’ and optimization of overall system.
We produced the following conclusions with the above researches.
- We developed an algorithm to differentiate between malignant mass and benign one with robustness against contrast change, brightness change, size change.
- We developed semi-automatic detection of region of interest (ROI).
- We developed retrieval algorithm based on nearest distance measure.
- We verified developed system requires only a few seconds to achieve the results.
- We can reduce 27.13％ needless biopsy with high sensitivity of 99.76％.
- At last, we verified that the developed system can be used as a decision support to differentiate between malignant and benign lesions.
