Automated centerline for computed tomography colonography1

Academic Radiology, 2003
Rationale and Objectives. A novel method to compute the centerline of the human colon obtained from computed tomography colonography is proposed. Two applications of this method are demonstrated: to compute local colonic distension (caliber), and to match polyps on supine and prone images. Materials and Methods.

Distance contained centerline for virtual endoscopy

2004 2nd IEEE International Symposium on Biomedical Imaging: Macro to Nano (IEEE Cat No. 04EX821), 2005
Collision detection and flight path planning are difficult problems in virtual navigation in complex environments, especially in endoscopic navigation inside human organs. We solve these problems in elongated environment through a combination of shape keeping centerline and the distance from each internal point to boundary.

Grooving Pavement Centerlines for Lane Demarcation

1969
Lane demarcation is conventionally accomplished by use of white traffic paint placed as a skip line. Most traffic paints are beaded by premixing glass beads in the paint, by drop-on applications, or a combination of the two. The retrodirective properties of the beads greatly enhance nighttime visibility during dry weather; however, visibility of the ...

Automated Centerline Tracing in Coronary Angiograms

1988
Recent developments in quantitative coronary angiography have been directed towards providing objective and reproducible measures about coronary anatomy during the catheterization procedure. The X-ray images of contrast-filled coronary arteries are converted into video format at the output screen of the image intensifier, digitized on-line and in real ...

Grooving Pavement Centerlines for Lane Demarcation

1971
In late June 1969, the Kentucky Department of Highways contracted to have experimental, longitudinal centerline grooves, 15 feet long at 80-foot intervals, cut into both sets of dual lanes of a 2.7-mile portion of I 71 in Carroll County. When the centerline was painted in an otherwise normal way, the skip lines were alternately on grooved and ungrooved
