Comparison of cephalometric measurements with digital versus conventional cephalometric analysis.
The aim of this study was to evaluate the accuracy and reliability of angular and linear cephalometric measurements using a computerized method of direct digital radiographs. This was then compared with the measurements obtained with a computerized method that uses a digitizing pad and hand tracing of printout radiographs. Pre-treatment digital cephalometric radiographs of 125 patients were tra...
متن کاملComparison of cone-beam computed tomography cephalometric measurements using a midsagittal projection and conventional two-dimensional cephalometric measurements.
OBJECTIVE This study investigated whether it is possible to use a two-dimensional (2D) standard in three-dimensional (3D) analysis, by comparing the angles and lengths measured from a midsagittal projection in 3D cone-beam computed tomography (CBCT) with those measured by 2D lateral cephalometric radiography (LCR). METHODS Fifty patients who underwent both LCR and CBCT were selected as subjec...
متن کاملAn evaluation of the errors in cephalometric measurements on scanned cephalometric images and conventional tracings.
The aim of this investigation was to compare the classic method of tracing by hand with a computerized method, where the lateral cephalograms were scanned at 300 dpi and digitized onscreen. The inter- and intra-observer errors were investigated for tracing and digitizing errors. Thirty lateral cephalograms were scanned into digital format at 300 dpi, displayed on a high-resolution monitor, and ...
متن کاملAutomatic Cephalometric Analysis Using Active Appearance Model and Simulated Annealing
This paper describes unifying Active Appearance Model and Simulated Annealing for automatic Cephalometric analysis. A complete model of shape and texture was built from a dataset of manually annotated images, and then tested with unseen images. A comparison with Active Shape Models was presented. Twenty randomly selected cephalograms were used for training and seven cephalograms for testing. 25...
