Ricketts' cephalogram norms observed in children from Matanzas
Revista Cubana de Estomatología, 2014 Introduction: the study of the growth and development processes allows identifying and making diagnosis of anomalies to determine as early as possible the most adequate treatment, with the criteria of preventing malocclusions with skeletal ...

A study on computed head posture compensation in three dimensional cephalogram
, 1998 Cephalogram is one of the most important tool in researching growth and development of craniofacial area, orthodontic diagnosis and treatment planning. But its inherent distortion of actual length and angles during projecting three dimensional object to ...

The skull base in NF1 phenotypes on lateral cephalograms
Journal of Cranio-Maxillofacial SurgeryNeurofibromatosis type 1 (NF1) influences skeletal growth processes. We investigated the effect of the disease and associated neurogenic craniofacial tumors on the skull base. We examined skull base parameters on lateral cephalograms in patients with (N = 74) facial plexiform neurofibroma (FPNF) and 92 without and the same number of age- and sex ...

Errors in digitizing and processing of cephalograms
, 2010 Aim: To measure "real" amount of error in everyday cephalometrics, to distinct between values that are more erroneuos from those that are not. Additionaly, we want to compare data between digital vs classical x-ray and different methods of processing.

Quantification of the distortion present in the postero-anterior cephalogram
Revista Cubana de Estomatología, 2019 Introduction: Universally, it has been accepted that the postero-anterior cephalogram presents less distortion than any other x-ray radiograph; for this reason, the measurements taken on it are considered reliable.

Extraction of Landmarks in Roentgenographic Cephalogram by Using Weighted Similarity Measure
, 1996 本論文では, ニューラルネットワークとファジィテンプレートマッチングを用いたセファロ画像における計測点の抽出について述べる.また, ファジィテンプレートマッチングにおいて, 新たな重み付き類似性測度を提案する.具体的には, まずニューラルネットワークを用いて計測点の大域的探索を行い, その後ファジィテンプレートマッチングにより局所的探索を行う.本手法の有効性は, 実際のセファロ画像への適用により確認された.This paper describes an extraction of landmarks ...

Digital image enhancement of cephalograms.
The Angle orthodontist, 1978 Quantification of cephalometric X-rays requires the use of hand tracings of the structures to delineate points, lines, and angles. The structures, especially soft tissue, are often obscure and are therefore approximated. Recent biomedical application of image enhancement by digital computer promises a method whereby landmarks in the cranium are more ...

Assessing the Diagnostic Value of Lateral Cephalometric Radiographs in Class I Dental Malocclusions
, 2019 Introduction: Controversy exists over the value of a lateral cephalogram for treatment planning in different malocclusion types. Discord has been found in the literature, and no studies on the matter have focused solely on Class I dental malocclusions ...
