(sī′nō-grăm″) [L. sinus, curve, + Gr. gramma, something written]
A radiograph of a sinus tract filled with a radiopaque contrast medium to determine the range and course of the tract.

Catheters were removed when patients had no sepsis, the fluid collection cavity had resolved by CT and catheter sinogram, drainage output was less than 10 mL per day, and there was no pancreatic or enteral fistula.
Catheters were irrigated daily, and catheter sinograms were systematically performed to evaluate the residual PFC cavity and the presence of a fistula.
The latter was achieved by means of catheter sinograms (tube checks).
The inverse problem is to reconstruct the Shepp-Vardi phantom given the respective sinogram data z and the forward model matrix A.
2b (bottom left) represents the respective density sinogram (Radon transform (Radon, 1917)) which is either achieved by computed projection of model densities (Fig.
This involves interpolation between neighboring sinogram pixels corresponding to different detector elements.
It is a challenging problem to judge whether a residual sinogram is dominated by erroneous information from projection noise and hence, further steps of iteration will only result in artifacts.
In order to assess the impact of noise on the reconstruction results we simulated intensity sinograms under a noisy X-ray source.
The subsequent steps of iteration (fourteen for reconstructions of ideal projections) were based on contrast-filtered sinograms, where the contrast filter [c.
Diagnosis of patient was made through clinical presentation and CECT sinogram which revealed type 4 branchial fistula.
The projections are re-arranged as sinograms for tomographic reconstructions.
Suggestions for correct identification of the sinus tracts included use of a small lacrimal probe,11 methylene blue intra-operative injection,612 Pre-operative sonographic imaging and Pre-operative sinograms.
