During the last decade, the quantitative ultrasound technique, especially the high frequency ultrasound elasticity measurement technique, called as ultrasound elastomicroscopy (UEM), has been widely employed as a versatile modality to investigate the articular cartilage. Ultrasound elastomicroscopy can measure the deformation of different layers of articular cartilage under compression, but whether the propagation of ultrasound in tissues was changed or not with the imposed load is still unknown. In this study, we developed a new optical method to validate the accuracy and reliability of the ultrasound elastomicroscopy. Layered sponge phantoms were prepared for the experiments. During the compression, both the ultrasound and optical elastomicroscopy systems were employed to record the ultrasound signals and optical images from inside and the font of the phantoms. The deformations of the phantoms from different layers were tracked from both ultrasound and optical signals and were then compared. The preliminary results suggest that the measurements of the ultrasound elastomicroscopy system could be validated.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":"7 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2010-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85488254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The removal and control effects of nitrobenzene by using Powered Activated Carbon (PAC) absorption and Granular Activated Carbon (GAC) filtration as emergent treatments were studied. The results showed that PAC dosage could change from 30mg/L to 50mg/L according to the variation of nitrobenzene concentration in raw water. The dosing point of PAC was at the intake of water source and enough adsorption time could be guaranteed by means of the water transportation pipeline with distance of 11.9km. Full scale study results showed that the nitrobenzene concentration in intake of water plant was below 0.005mg/L after 5 hours adsorption by PAC in intake of water source which nitrobenzene concentration was between 0.03~0.35mg/L.With the GAC filtration as following treatment, nitrobenzene concentration was below 0.001mg/L in purified water.
