Internal inspection of semi-transparent objects by digital holographic micro-tomography
(Elsevier Gmbh, 2013-09)
The combined use of digital holographic microscopy and computer tomography, here named digital holographic micro-tomography, is used to examine the interior of transparent channels. The proposed method is used to identify ...
Comparison between cone-beam and multislice computed tomography for identification of simulated bone lesions
(Sociedade Brasileira de Pesquisa Odontológica, 2011)
There are many studies that compare the accuracy of multislice (MSCT) and cone beam (CBCT) computed tomography for evaluations in the maxillofacial region. However, further studies comparing both acquisition techniques for ...
Intranasal osteosarcoma in a blood hound dog: computed tomography, cytological and histopathological findings
Osteosarcoma is a common neoplasm described predominantly in large breed dogs. Most of the cases occur in the long bones, but other anatomical locations, such as axial skeleton and extra-skeletal sites, are also described. ...
Large axial range frequency-domain optical low coherence interferometry
(Institute of Electrical and Electronics Engineers, 2019-01)
In this letter, we propose a new experimental setup to extend the measurement range of frequency-domain low coherence interferometry (FD-LCI) from 3 mm to 2 cm. The FD-LCI can be extended to the technique of frequency ...
Estudo tomográfico do atlas relacionado com a inserção de implantes na massa lateral
(Atha Comunicação & Editora, 2009)
INTRODUÇÃO: A técnica de Harms para a realização da artrodese atlantoaxial possibilita o uso de manobras de redução transoperatória da subluxação atlantoaxial e facilita a fixação dessa articulação, principalmente nos ...
Manufacturing of a maxillofacial prosthesis from an axial tomography using simulation technologies with a virtual machine tool and four-axis machining
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-03-01)
The surfaces of a personalized maxillofacial prosthesis were manufactured in a relatively short time with moderate cost. The topography of the surface was generated with a Computer-Aided Design system from a Computerized ...
A Comparative Analysis between Ultrasonometry and Computer-Aided Tomography to Evaluate Bone Healing
An ultrasonometric and computed-tomographic study of bone healing was undertaken using a model of a transverse mid-shaft osteotomy of sheep tibiae fixed with a semi-flexible external fixator. Fourteen sheep were operated ...

Predicting dysthyroid optic neuropathy using computed tomography volumetric analyses of orbital structures
(HOSPITAL CLINICAS, UNIV SAO PAULOSAO PAULO, 2012)
OBJECTIVE: To evaluate the ability of orbital apex crowding volume measurements calculated with multidetector-computed tomography to detect dysthyroid optic neuropathy. METHODS: Ninety-three patients with Graves' orbitopathy ...
Cone beam computed tomography study of apical root resorption induced by Herbst appliance
(Univ Sao Paulo Fac Odontologia Bauru, 2015-09-01)
Objective: This study evaluated the frequency of root resorption during the orthodontic treatment with Herbst appliance by Cone Beam Computed Tomography (CBCT). Material and Methods: The sample comprised 23 patients (11 ...
