Measurement of Diesel Nozzle Geometry with X-Ray Phase Contrast Imaging Technique

Diesel spray characteristic s is affected by nozzle geometry and then influences the subsequent combustion and emission, so it's important to get the detail nozzle geometry dimensions. In this paper, the X-Ray phase contrast imaging technique was proposed to measure the nozzle geometry. With X-microtomography technique and three-dimension reconstruction technique, the internal structure of nozzle is constructed. The non-destructive measurement was performed and the detail structure of nozzle was got.

Absorption Contrast

With X-ray phase contrast imaging technique, the pulmonary lesions induced by multi-walled carbon nanotubes were preliminarily studied in this work. After 0.1, 1 and 2 mg nanotubes were delivered into lungs of rats via trachea, their acute pulmonary toxicity (at 5-day postexposure) was assessed using X-ray phase contrast, absorption contrast imaging and routine pathological slice techniques. As such, the long-term pulmonary toxicity (at 140-day postexposure), induced by single intratracheal instillation of 0.1 mg nanotubes, was assessed using X-ray phase contrast imaging and pathological slice techniques. As a consequence, the nanotubes could induce obvious density and structural integrity alternation in lung tissue at 5-day postexposure and granulomas at 140-day postexposure, and these pathologic lesions could be efficiently detected out with the phase imaging technique. By comparison, this technique not only gained advantage over the conventional X-ray absorption contrast imaging but also could supply the gap of routine pathological slice in detecting pulmonary lesions induced by carbon nanotubes. It is hoped that this work can act as an impetus for further application of phase imaging technique to nanotoxicology and to assessment of occupational safety of nanomaterials.
