Observer-independent registration of perspective projection prior to subtraction of in vivo radiographs.
OBJECTIVES To prove that the model of perspective projection allows precise registration of intra-oral radiographs regardless of whether they have been acquired with or without individual adjustment aids and independent of the human observer or computer algorithm marking corresponding landmarks in the images and, based on in vivo radiographs, to introduce and evaluate a model-based registration...
متن کاملA digital subtraction radiography scheme based on automatic multiresolution registration.
OBJECTIVES To establish a digital subtraction radiography scheme for aligning clinical in vivo radiographs based on the implementations of an automatic geometric registration method and a contrast correction technique. METHODS Thirty-five pairs of in vivo dental radiographs from four clinical studies were used in this work. First, each image pair was automatically aligned by applying a multir...
متن کاملDesigning a logical data model of athletes' hospital information management system based on international standards
Background and purpose: Today, hospital care, relying on the health record system, has received more attention than before. Considering the diversity of data in these systems, the design of standard conceptual and logical models by service providers will play an important role in their success. Therefore, this research was conducted with the aim of designing a logical data model of the hospital...
متن کاملA Robust Algorithm for Automatic Registration of Intraoral Radiographs
Background Subtraction techniques enable precise quantiication of changes in dental tissue structure. Automatic subtraction of intra-oral radiographs acquired without individual adjustment aids requires a-posteriori correction of geometry and contrast diierences, i.e. registration. Methods Previous work has shown that perspective projection is a reliable model for sequential radiographs regardl...
متن کاملCalculation of Inter- and Intra-Fraction Motion Errors at External Radiotherapy Using a Markerless Strategy Based on Image Registration Combined with Correlation Model
Introduction: A new method based on image registration technique and an intelligent correlation model to calculate. The present study aimed to propose inter- and intra-fraction motion errors in order to address the limitations of conventional Patient positioning methods. Material and Methods: The configuration of the markerless method wa...
