Journal ArticleDOI
GI tract unraveling with curved cross sections
TL;DR: An electrical-field-based method to unravel the convoluted colon is proposed, that is, to digitally straighten it with curved cross sections and flatten it over a plane to produce a global planar view of complicated colon features with a potential for detection of polyps.
Journal ArticleDOI
Accuracy of facial soft tissue thickness measurements in personal computer-based multiplanar reconstructed computed tomographic images.

TL;DR: PC-based MPR CT images of the face using routine scanning CT protocols can be used to accurately measure soft tissue thickness in the facial region, however, for more fine and accurate data collection, scanning protocols with slice thicknesses less than 5mm, and a spiral/helical mode pitch less than 2:1 are recommended.
Journal ArticleDOI
Spiral CT: decreased spatial resolution in vivo due to broadening of section-sensitivity profile.
TL;DR: In vivo transaxial CT studies showed that the conventional scans produced slightly sharper edges than the spiral scans, whereas in vivo MPR Studies showed that interfaces in the xy plane were significantly less sharp with spiral scanning, whereas interface in the z direction were equivalent for conventional and spiral scanning.
Journal ArticleDOI
Complex musculoskeletal anatomy: analysis using three dimensional surface reconstruction.
TL;DR: A new computer method has been developed that allows the reprocessing of standard CT scans to produce three dimensional surface images, and reconstruction time is comparable to that of sagittal and coronal reconstruction.
Journal ArticleDOI
Quantitative analysis of spiral computed tomography for craniofacial clinical applications.
TL;DR: Three-dimensional spiral CT can distinguish craniofacial anatomy more accurately with some measurements, and all measurements with 3DCT were found to have satisfactory accuracy in comparison with physical measurements.
