Kilovoltage cone-beam computerized tomography (kV-CBCT) systems integrated into the gantry of linear accelerators can be used to acquire high-resolution volumetric images of the patient in the treatment position. Using on-line software and hardware, patient position can be determined accurately with a high degree of precision and, subsequently, set-up parameters can be adjusted to deliver the i...

Introduction: The application of 3D volumetric imaging modalities in treatment planning of radiation therapy can provide more precisely define tumor localization, and computed tomography (CT) is the most common accepted method for treatment planning. Given the lack of a CT scanner stationed in all radiotherapy departments and equipping most of the medical linear accelerators wi...

Aim: To assess the response of clinicians and patient towards various imaging modalities used in diagnostic evaluation of dental implant therapy. Materials and Methods: 200 clinicians with more than 5 years of experience in implant dentistry were selected in study. Every clinician was requested to judge accessibility, maneuverability, accuracy, reproducibility, reliability, ease of understandin...

  Objective: Diagnosis of vertical root fractures (VRFs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. Despite Cone Beam Computed Tomography (CBCT) has significantly enhanced image quality compared to digital radiography (DR) which aid the diagnosis, artifacts has remained as a problem in VRF detection . ...

Abstract Objectives To measure in vivo 3D accuracy of backward‐planned partially guided implant surgery (PGIS) based on dental magnetic resonance imaging (dMRI). Material and Methods Thirty‐four patients underwent dMRI examinations. Tooth‐supported templates were backward planned using standard software, 3D‐printed, placed intraorally during a cone beam computed tomography (CBCT) scan. Treatmen...

as you will no doubt notice, this issue of the AJO-DO includes our annual Product Guide, which highlights many materials that we use daily in our private practices. as in the past, we have given this issue a special theme. all original, online, and techno Bytes articles in this issue are on the topic of three-dimensional (3d) imaging. We are presenting articles that not only discuss cone-beam c...

Abstract Background The aim of this study was to compare the trabecular bone microstructures anterior and posterior edentulous regions human mandible using cone-beam computed tomography (CBCT) micro (µCT). Methods Twenty volumes interests consisting six fourteen were obtained from mandibular cadavers. A CBCT system with a resolution 80 µm (3D Accuitomo 170, J. Morita, Kyoto, Japan) µCT 35 (SkyS...

OBJECTIVE The objective of this study was to determine the most suitable material for indirect pulp treatment (IPT) clinically and to determine the thickness (in mm) and type of tissue in terms of radiodensity (in Hounsfield units [HU]) formed after pulp capping using cone-beam computed tomography (CBCT) scan. MATERIALS AND METHODS A longitudinal interventional single-blind randomized clinica...

Background The Optical Surface Management System (OSMS) is a simple, fast, reproducible, and accurate solution for patient set-up and can minimize random day-to-day set-up errors. However, studies in breast cancer patients are rare. Objective To analyze 200 patient set-ups in 20 patients with breast cancer by comparing the OSMS with the conventional cone-beam computed tomography (CBCT). Met...
