Outline of Final Research Achievements

This project developed an image analysis technique to evaluate cancer tumors from contrast-enhanced ultrasound images. The developed technique consists of spatiotemporal filters, motion estimation and statistical analysis to detect small contrast agents in ultrasound images. Through a set of experiments using mice, the developed technique is useful for observing temporal changes in microvessel density in subiliac lymph nodes containing tumors. The results are compared with those of contrast-enhanced computed tomography.
