Download or read book Comparative Linear Accuracy and Reliability of Cone Beam CT Derived 2 dimensional and 3 dimensional Images Constructed Using an Orthodontic Volumetric Rendering Program written by Danielle R. Periago and published by . This book was released on 2007 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to compare the accuracy and reliability of linear measurements made on 2D projections and 3D reconstructions using Dolphin 3D software (Chatsworth, CA) as compared to direct measurements made on human skulls. The linear dimensions between 6 bilateral and 8 mid-sagittal anatomical landmarks on 23 dentate dry human skulls were measured three times by multiple observers using a digital caliper to provide twenty orthodontic linear measurements. The skulls were stabilized and imaged via PSP digital cephalometry as well as CBCT. The PSP cephalograms were imported into Dolphin (Chatsworth, CA, USA) and the 3D volumetric data set was imported into Dolphin 3D (Version 2.3, Chatsworth, CA, USA).Using Dolphin 3D, planar cephalograms as well as 3D volumetric surface reconstructions were (3D CBCT) generated. The linear measurements between landmarks of each three modalities were then computed by a single observer three times. For 2D measurements, a one way ANOVA for each measurement dimension was calculated as well as a post hoc Scheffe multiple comparison test with the anatomic distance as the control group. 3D measurements were compared to anatomic truth using Student's t test (P [less than or equal to] 50.05). The intraclass correlation coefficient (ICC) and absolute linear and percentage error were determined as indices of intraobserver reliability. Our results show that for 2D mid sagittal measurements that Simulated LC images are accurate and similar to those from PSP images (except for Ba-Na), and for bilateral measurements simulated LC measurements were similar to PSP but less accurate, underestimating dimensions by between 4.7% to 17%.For 3D volumetric renderings, 2/3 rd of CBCT measurements are statistically different from actual measurements, however this possibly is not clinically relevant.
Download or read book Cone Beam Computed Tomography in Orthodontics written by Sunil D. Kapila and published by John Wiley & Sons. This book was released on 2014-08-29 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its introduction to dentistry, cone beam computed tomography (CBCT) has undergone a rapid evolution and considerable integration into orthodontics. However, despite the increasing popularity of CBCT and progress in applying it to clinical orthodontics, the profession has lacked a cohesive, comprehensive and objective reference that provides clinicians with the background needed to utilize this technology optimally for treating their patients. Cone Beam Computed Tomography in Orthodontics provides timely, impartial, and state-of-the-art information on the indications and protocols for CBCT imaging in orthodontics, clinical insights gained from these images, and innovations driven by these insights. As such, it is the most current and authoritative textbook on CBCT in orthodontics. Cone Beam Computed Tomography in Orthodontics is organized to progress sequentially through specific topics so as to build the knowledgebase logically in this important and rapidly evolving field. Part I provides the foundational information on CBCT technology, including radiation exposure and risks, and future evolutions in computed tomography. Part II presents the Principles and Protocols for CBCT Imaging in Orthodontics, focusing on developing evidence-based criteria for CBCT imaging, the medico-legal implications of CBCT to the professional and the protocols and integration of this technology in orthodontic practice. Part III provides critical information on CBCT-based Diagnosis and Treatment Planning that includes how to interpret CBCT scans, identify incidental pathologies and the possible other uses of this technology. Part IV covers practical aspects of CBCT’s Clinical Applications and Treatment Outcomes that encompasses a range of topics, including root morphology and position, treatment of impacted teeth, virtual surgical treatment planning and outcomes, and more.

This book was released on 2008 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to compare the accuracy and precision of linear measurements made on conventional lateral cephalograms (LC) and simulated LC using cone-beam computed tomography (CBCT) to direct measurements on dentate skulls. The linear distances for 5 mid-sagittal and 4 bilateral measurements between anatomical landmarks on 22 skulls were measured by two observers. The skulls were imaged using a CBCT scanner at 4 scan settings: high resolution (0.2mm) and normal resolution (0.4mm) at 20-sec (306 projections) and 40-sec scans (612 projections). Three simulated LC were generated: Ray sum image reconstructions of the maximum thickness mid-sagittal multiplanar projections, a single frame basis projection, and the scout image. LCs were acquired using a storage phosphor system. Projection images were exported into a cephalometric analysis program and linear measurements determined. Analyses were repeated three times and statistically compared to measured anatomic truth using repeated measures general linear model (p [less than or equal to] 0.05). The mean absolute error was used as an index of precision. While there were statistical differences between skull and modality measurements for 6 of the nine measurements, there were no overall differences between LC and CBCT derived image measurements irrespective of method of construction. CBCT imaging provides clinically reliable 2D simulation images however, dose considerations demand that evidence-based selection criteria should be developed for CBCT in orthodontics that take into account the ALARA principle.
Download or read book Comparative Linear Accuracy of Cone Beam CT Derived 3D Images in Orthodontic Analysis written by April A. Brown and published by . This book was released on 2008 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective. To compare the in vitro reliability and accuracy of linear measurements between cephalometric landmarks on CBCT 3D images with varying basis projection images to direct measurements on human skulls. Methods. Sixteen linear dimensions between anatomical sites marked on 19 human skulls were directly measured. Skulls were imaged with CBCT at three settings: 153, 306, and 612 basis projections. The mean absolute error and modality mean of linear measurements between landmarks on 3D images were compared to the anatomic truth. Results. No difference in mean absolute error between the scan settings was found. The average skull absolute error between marked reference points were less than the distances between unmarked reference sites. Conclusion. CBCT measurements were consistent between scan sequences and for direct measurements between marked reference points. Reducing the number of projections for 3D reconstruction did not lead to reduced dimensional accuracy and potentially provides reduced patient radiation exposure.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive review of the state of the art in Ultrasonography (USG) dentomaxillofacial imaging to help radiologists and dentists in their training and daily practice. The book examines the relationship between clinical features, diagnosis, and choice of minimally invasive technique for a range of dentomaxillofacial disorders and provides information on post-treatment therapy. Accurate interpretation of indications for treatment is the cornerstone of success in medicine, and as such, the book explains how the selection of imaging technique is closely linked to clinical and diagnostic aspects and how recognition of this relationship forms the foundation for optimal outcomes. In addition to examining the various modalities, the book highlights the role of the latest USG imaging techniques. Further, it discusses in detail the pathology, treatment, and prognosis of common and rare diseases, as well as congenital/developmental malformations in the dentomaxillofacial, an area that is often underestimated and largely ignored by dentists. Featuring updated high-resolution images created with state-of-the-art equipment, the book introduces readers to current imaging modalities. It also includes pathological descriptions of radiologic diagnoses to help clarify the pathophysiology of the disease, while the pearls and pitfalls of image interpretation provide a quick reference guide for practitioners. Written by leading international experts, this outstanding book is a valuable resource for both radiologists, dentists and students seeking a more in-depth appreciation of the subject and its contribution to the scientific radiology community.
Download or read book Comparative Accuracy of Linear Measures from Conventional Digital and Cone Beam Computed Tomography Simulated Posterior Anterior Cephalograms written by Brian M. Mannari and published by . This book was released on 2007 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to compare the accuracy and reliability of linear measurements on posterior-anterior (PA) cephalograms made conventionally using photostimulable storage phosphor imaging plates (PSP) and simulated PA cephalometric images from ray sum reconstruction of cone beam computed tomographic (CBCT) volumetric datasets of the same anatomic specimens. The sample consisted of 19 dried dentate human skulls which were imaged using PA cephalometry using PSP imaging plates and three CBCT datasets at 10 s., 20 s. and 40 s. scanning times from which ray sum simulated PA images were produced. Various anatomic landmarks were identified and truth measurements of 13 selected cephalometric linear dimensions were measured directly on the skulls using a high precision caliper. CBCT datasets were imported into a reconstruction program (Dolphin 3D Software) from which ray sum PA images were constructed. Linear cephalometric measurements on PSP and CBCT simulated PA images were performed by one observer using Dolphin Imaging Software. Intraobserver reliability was determined by calculating and comparing Intraclass correlation coefficient. Mean absolute and percentage errors were calculated for each dimension and modality to quantify the reliability error. Mean modality measurements were compared. All other groups were compared using one-way ANOVA with Tukey post hoc comparisons (p [less than or equal to] 0.05). While the ICC was high, PSP cephalometric absolute error was greater than anatomic distances and CBCT image measurements for 8 for 13 measurements. We found that for most measurements, simulated PA images produced from reconstructed CBCT volumetric dataset were accurate and compared well to PSP cephalometric images except for Z-Ag. We also found that PSP cephalometric images consistently underestimated MO-MO dimensions. Measurements on CBCT simulated PA images are more reliabile and as accuracte as PSP cephalometric measurements. The number of projections comprising the reconstructed simulated PA image did not influence reliability or accuracy. Therefore in accordance with ALARA, when CBCT imaging is used to generate simulated PA images, the lowest number of projections are recommended.
