Název v původním jazyce

Helical XCT measurement for correlative imaging

Popis výsledku v původním jazyce

The X-ray computed tomography (XCT) is more often used to scan long objects that exceed the dimensions of the detector. Convantional scans/systems using circular trajectrories touches the limits when dealing whit an elongated samples. Helical scanning is a valuable solution in such a cases. It enables to shorten scanning time, getting strong improvement on image quality, eliminating the cone beam artifacts and beam hardening. These benefits makes from the helical trajectory strong tool for correlative approaches with other imaging techniques. In this work, images obtained by helical trajectory are investigated and compared with those acquired by conventional circular scans. Experimental results show that helical scanning with appropriate scan parameters, performs better quality than traditional circulat scans with an improvement on image quality.
