3D Multislice and Cone-beam computed tomography (CBCT) in forensic odontology has been shown to be useful not only in terms of one or a few of dead bodies but also in multiple fatality incidents. 3D Multislice and Cone-beam computed tomography and digital radiography were demonstrated in a forensic examination form. 3D images of the skull and teeth were analysed and validated for long ante mort...

Imaging procedures are a mainstream tool in the daily ENT workflow. Cochlear Implant patients are representing a special population with specific demands for imaging. There are different imaging techniques available for pre-operative evaluation, surgery and postoperative controls with different indications and consequences. High-resolution computed tomography and magnetic resonance imaging are ...

Aims: The purpose of this review includes the following: 1) to identify indications for volumetric X-ray digital linear tomosynthesis by using a filtered back projection (FBP) algorithm and 2) to compare X-ray digital linear tomosynthesis, X-ray digital radiography, conventional tomography, and computed tomography. Review: The methods include the following: 1) an overview of the tomosynthesis s...

Modern treatment of adult patients with complex dental problems often requires an interdisciplinary collaboration between different specialties of dental medicine among them frequently orthodontics: interdisciplinary orthodontics. Good diagnostic tools and easy communication are essential in such complicated cases. Computer technology has an increasing impact in the practice of orthodontics; ev...

Objective(s): Alternative normalization methods were proposed to solve the biased information of SPM in the study of neurodegenerative disease. The objective of this study was to determine the most suitable count normalization method for SPM analysis of a neurodegenerative disease based on the results of different count normalization methods applied on a prepared digital phantom similar to one ...

Although ultrasound, computed tomography, magnetic resonance imaging and nuclear medicine are digital, they have been displayed in analogue format in the form of films. Other modalities like digital radiography units and scanning of conventional films (computed radiography) are accepted technologies with resolution similar to the conventional film/screen. This advancement in technology is criti...

Several methods have been proposed to integrate digital models into Cone Beam Computed Tomography scans. Since all these methods have some drawbacks such as radiation exposure, soft tissue deformation and time-consuming digital handling processes, we propose a new method to integrate digital dental casts into Cone Beam Computed Tomography scans. Plaster casts of 10 patients were randomly select...

Neuroimaging is a key element in the management of patients suffering from subarachnoid haemorrhage (SAH). In this article, we review the current literature to provide a summary of the existing neuroimaging methods available in clinical practice. Noncontrast computed tomography is highly sensitive in detecting subarachnoid blood, especially within 6 hours of haemorrhage. However, lumbar punctur...
