Outline of Final Research Achievements

To ensure the safety and certainty of peripheral intravenous access, we modified fluoroscopy technology and image processing technology.
We examined the positional relation of the camera body, a light source, and skin, and the polarization angle. As a result, these variables were affected visual performance of the peripheral veins and the optimum value near the best. However, the experimental device can not visualize to deep veins. The modified image processing improved the visualization rate with enhancement of contrast techinique. The other image processing improved to effective image for clinical use in vein puncture.
