Our pourpose was to compare the radiographic diagnostics observed in bitewing and panoramic techniques a sample of 50 adult patients' x-rays, examined by same observer. On it analyzed area corresponding bitewings, looking for coincident diagnostics. Furthermore evaluated additional information supplied technique. The proportion bitewings significantly larger suggesting no differences between as...

For multi-sensor integrated systems, such as the mobile mapping system (MMS), data fusion at sensor-level, i.e., the 2D-3D registration between an optical camera and LiDAR, is a prerequisite for higher level fusion and further applications. This paper proposes a line-based registration method for panoramic images and a LiDAR point cloud collected by a MMS. We first introduce the system configur...

In this article, we present some development results of a system that performs mosaicing (or mosaicking) of panoramic faces. Our objective is to study the feasibility of panoramic face construction in real-time. To do so, we built a simple acquisition system composed of 5 standard cameras which, together, can take simultaneously 5 views of a face at different angles. Then, we chose an easily ha...

In this paper, we present a novel method to generate a panoramic background image from a sequence of moving camera images. Our method is based on nonparametric statistics and robust model estimation using meanshift. Each frame is projected to panoramic space by homography matrix which is calculated by SURF(Speeded Up Robust Features) matching. To generate reliable panoramic background image, we...

PURPOSE The present study was performed to compare the planning of implant placement based on panoramic radiography (PAN) and cone-beam computed tomography (CBCT) images, and to study the impact of the image dataset on the treatment planning. MATERIALS AND METHODS One hundred five partially edentulous patients (77 males, 28 females, mean age: 46 years, range: 26-67 years) seeking oral implant...

BACKGROUND The purpose of this study was to investigate the presence of punched-out lesions in craniofacial bones using three different radiographic protocols in a large cohort of patients. MATERIAL AND METHODS One hundred fifty-five MM patients were evaluated using panoramic and skull (frontal and lateral) radiographs, which were performed in all patients at the time of MM diagnosis. The dia...

OBJECTIVE To compare the mesiodistal root angulation of panoramic images generated from traditional panoramic tomography or cone-beam computed tomography (CBCT). METHODS CBCT scans and panoramic radiographs of 20 patients were collected. The Invivo- Dental 5.0 was separately applied for maxillary or mandibular panoramic image generation. The generation method was assorted by two head position...

PURPOSE The aim of this study was to assess and compare the diagnostic performance of panoramic and occlusal radiographs in detecting submandibular sialoliths. MATERIALS AND METHODS A total of 40 patients (20 cases and 20 controls) were included in this retrospective study. Cases were defined as subjects with a submandibular sialolith confirmed by computed tomography (CT), whereas controls di...
