Title:
Modeling of esophageal bolus flow by functional data analysis of scintigrams.
Abstract:
Peristaltic forces cause a topographic, time-dependent distribution of bolus mass during its esophageal transport. A two-dimensional spatial-temporal pattern (profile) of local transit times is constructed by computer-based double compression of scintigraphic images sampled from whole swallows. Reconstruction by Gaussian bands and modeling this pattern discloses transient ellipsoidal bolus structures. The structures studied in 10 healthy volunteers present highly reproducible quantitative parame...     »
