| Outline of Final Research Achievements |
To detect lymph node micrometastasis, we developed a volume registration method for analyzing the vessel structure in the lymph node by using Scale-Invariant-Feature-Transform and Phase-Only Correlation methods. The algorithm developed here was for correcting images for evaluation of ultrasound images of the experimental metastatic lymph node, and also for calculating highly accurate information of blood vessel considering the dispersion value due to temporal change of luminance information and those before and after contrast agent administration. As a result, it was possible to eliminate misalignment and noise of the ultrasound images, and also extract the microstructure of the blood vessels in the metastatic lymph node.
