The list of functionalities which should be included into such a system is described. The system enables the user to edit the thickness of dowels and their directions, which results in building an editable model of the surface of the skin. The set of dowels called the “Rhine configuration” [1,2] is used by default , but there is a possibility to make new statistics for the population being analysed. Further processing is required and the paper shows the ideas of an algorithm of surface splitting taking into consideration the curvature of the skull or, for example, the use of morphing techniques.01092nas a2200121   4500000000100000000000100001008004100002100002100043700002600064700002300090245010600113520075100219       2006                            d1 aSzymon Kadłubek1 aAgnieszka Anna Tomaka1 aRyszard Winiarczyk00aComputer System for the Registration and Fusion of Multimodal Images for the Purposes of Orthodontics3 a<p>The paper presents aspects connected with development of a computer system for registration and fusion of multimodal images for orthodontic purposes. The idea of the system, of the multimodal image registration, lies in 3D surfaces registering, reconstructed from the sets of MRI or CT planar slices. The system enables the user to perform registration using different approaches based on localised landmarks, based on selected regions of 3D surfaces or based on automatic matching of the whole surfaces. The rigid-body transformation found during the registration is then used to transform the set of slices to generate images that can be fused. The usage of the system was illustrated and the accuracy of the registration was assessed.</p>

The cooperation began from the inspiration of late prof. A. Mrózek. Computer Vision in supporting orthodontic diagnosis means all the problems connected with proper acquisition, calibration and analysis of the diagnostic images of orthodontic patients. The aim of traditional cephalometric analysis is the quantitative confirmation of skeletal and/or soft tissue abnormalities on single images, assessment of the treatment plan, long term follow up of growth and treatment results. Beginning with the computerization of the methods used in traditional manual diagnosis in the simplest X-ray films of the patient’s head we have developed our research towards engaging different methods of morphometrics, deformation analysis and using different imaging modalities: pairs of cephalograms (lateral an frontal), CT-scans, laser scans of dental models, laser scans of soft tissues, finally merging all the image information into patient’s specific geometric and deformable model of the head. The model can be further exploited in the supporting of the surgical correction of jaw discrepancies. Our laboratory equipment allows us to design virtual operations, educational programs in a virtual reality with a CyberGlove device, and finally to verify the plan of intervention on stereolithographic solid models received from a 3D printer.00363nas a2200145   4500000000100000000000100001008004100002260000700043100002600050700003100076245007600107300001400183490000600197022001400203       2005                            d  c101 aAgnieszka Anna Tomaka1 aB.

Jej celem jest wyodrębnienie obszarów twarzo-czaszki w których istnieją określone tendencje rozwojowe i opisanie tych tendencji. Wszystkie zmiany w tych zachodzące w tych obszarach zarówno na skutek normalnego wzrostu, istniejących patologii czy zabiegu chirurgicznego, bądź też wynikające z porównania obszarów wzajemnie symetrycznych określane są ogólnie jako deformacja. Metody stosowane w analizie deformacji powinny cechować się łatwą do odczytania przez lekarzy semantyką. Z tego względu analiza jest przeprowadzana na podstawie tzw. punktów charakterystycznych, wskazywanych przez lekarza na teleradiogramach, wykonanych w różnych chwilach czasu. W referacie przedstawiono metody opisu deformacji na płaszczyźnie teleradiogramów wychodząc od tradycyjnie stosowanych w Polsce metod, aż po metodę tensorów Booksteina i metody zaczerpnięte ze współczesnej mechaniki. Pokazano dlaczego wyniki analiz płaszczyznowych, przeprowadzonych na podstawie cefalogramów, wydają się być niewystarczające i jakie warunki powinny zostać spełnione, aby móc analizę zachodzącej deformacji przeprowadzić w trzech wymiarach. Zaproponowano rozszerzenie metody tensorów na przypadek trójwymiarowy. Rozpatrzono zagadnienia związane z komputerową implementacją tych metod, a więc z akwizycją punktów charakterystycznych, kalibracją i skalowaniem obrazów o różnym powiększeniu, pozycjonowaniem pary wzajemnie ortogonalnych teleradiogramów, wyborem odpowiednich parametrów do wyznaczania, a następnie prezentacją wyników.

All image data for one person form the patient specific record, which can be used for dignosis, progonosis, treatment planning, and the evaluation of treatment outcome, however, the analyzes performed for particular imaging modalities have to be integrated in the mind of a medical specialist. The paper presents an integration method for multimodal imaging data. The main idea relies on registration - a transformation of various imaging data into the same coordinate system, connected with the patient. A type of transformation has to be defined for each modality, according to the data representation used. The basis assumption is the presence, in the imaging data from various modalities, of common areas, which can be used to find the transformation through an optimization process. For disjoint images, where such common areas are not available, the use of additional reference objects is suggested and special transferring devices are designed. Registration of 3D images acquired at the same time amounts to a seek for a rigid-body transformation. Relating 2D and 3D images to each other involves identifying a projection. Presented examples of integration of multimodal image data include: fusion of 3D facial photography and digital dental models, producing digital gnathostatic models; segmenting the CT data with separation of craniomaxillary complex and the mandible using virtual dental models: determinig patient position during radiographic examination.</p>

  The purpose of this chapter is to discuss methods of acquisition,
visualization and analysis of the dynamics of a complex biomedical system,
illustrated by the human stomatognathic system. The stomatognathic system
consists of the teeth and the skull bones with the maxilla and the mandible.
Its dynamics can be described by the change of mutual position of the
lower/mandibular part versus the upper/maxillary one due to the physiological
motion of opening, chewing and swallowing. In order to analyse the dynamics of
the stomatognathic system its morphology and motion has to be digitized, which
is done using static and dynamic multimodal imagery like CBCT and 3D scans data
and temporal measurements of motion. The integration of multimodal data
incorporates different direct and indirect methods of registration - aligning
of all the data in the same coordinate system. The integrated sets of data form
4D multimodal data which can be further visualized, modeled, and subjected to
multivariate time series analysis. Example results are shown. Although there is
no direct method of imaging the TMJ motion, the integration of multimodal data
forms an adequate tool. As medical imaging becomes ever more diverse and ever
more accessible, organizing the imagery and measurements into unified,
comprehensive records can deliver to the doctor the most information in the
most accessible form, creating a new quality in data simulation, analysis and
interpretation.</pre>

Laser scanners and other precision 3D imaging devices are expensive and cumbersome, which limits their use in medical practice. Photogrammetry, using ordinary 2D photographs or video recordings to create 3D imagery, offers a cheaper and more convenient alternative, replacing&nbsp; the specialised equipment with handy consumer cameras. The present paper addresses the question to what extent, and under what conditions, this technique can be an adequate replacement for the 3D scanner. The accuracy of simple surface reconstruction and of model embedding achieved with photogrammetry was verified against that obtained with a triangulating laser scanner.</p>

<p>To roughly evaluate the impact of image imperfections on photogrammetric reconstruction, the photographs for photogrammetry were taken under various lighting conditions and used either raw or with a blur simulating defocus. Video footage was also tested as another 2D imaging modality feeding data into photogrammetry. Results show significant potential of photogrammetric techniques.</p>

This methodological proof-of-concept study presents a computer-aided approach for designing and evaluating occlusal positioning splints. The primary aim is to demonstrate the feasibility and geometric accuracy of the proposed method at the preclinical stage. In this approach, a three-dimensional splint is generated using a transformation matrix to represent the therapeutic mandibular position. An experienced operator defines this position using a virtual patient model reconstructed from intraoral scans, CBCT, 3D facial scans, and a digitized plaster model. We introduce a novel method for generating splints that reproduces occlusal conditions in the therapeutic position and resolves surface conflicts through virtual embossing. The process for obtaining transformation matrices using dental tools and intraoral devices commonly employed in dental and laboratory workflows is described, and the geometric accuracy of both designed and printed splints is evaluated using profile and surface deviation analysis. The method supports reproducible, patient-specific splint fabrication and provides a transparent foundation for future validation studies, supporting multimodal image registration and quantification of occlusal discrepancies in research settings.</p>

We propose a transformation-driven framework for synthetic projection imaging from multimodal anatomical data and demonstrate it on mandibular-motion scenarios.
In contrast to conventional Digitally Reconstructed Radiograph (DRR) approaches primarily designed for registration, projection realism, or rendering efficiency, the proposed formulation treats projection imaging as an observation process operating on an explicitly represented anatomical scene.
Independently transformable volumetric and surface-based anatomical objects are embedded within a shared scene representation and propagated directly into projection space through explicit transformations. Projection geometry, acquisition modelling, material interpretation, and image presentation remain explicitly separated, enabling controlled exploration of methodological assumptions while preserving reproducibility and direct comparability between generated projections.
Particular emphasis is placed on transformation-driven anatomical scenarios relevant to craniofacial analysis, including mandibular motion and therapeutic repositioning. Using a shared anatomical reference scene composed of CT/CBCT volumes, segmented structures, surface models, and auxiliary anatomical or therapeutic objects, the framework enables generation of directly comparable VirtualRTG projections from multiple anatomical configurations while preserving identical imaging assumptions.
Rather than aiming at fully physically faithful radiographic simulation, the proposed approach provides a controllable and reproducible methodological environment for studying anatomy--projection relationships, motion observability, and transformation-aware imaging workflows.
