detection of foreign bodies by spiral computed tomography and cone beam computed tomography in maxillofacial regions
background and aims. the imaging techniques commonly used for foreign body detection include plain radiography, xeroradiography, computed tomography (ct) scans, magnetic resonance imaging (mri) and ultrasonography. the aim of the present study was to compare cone-beam computed tomography (cbct) with conventional ct scan in determination of the exact location of a foreign body in the maxillofaci...
متن کاملSpontaneous hemorrhage during cranial computed tomography.
Computed tomographic (CT) scann ing is very accurate in the recog nition of intracerebral hemorrhage. However, when radiographic contrast material has been administered, there may be confus ion between an unsuspected hematoma and an enhancing brain lesion . We recently encountered two cases of spontaneous hemorrhage occurring during the enhancement phase of the CT examination immediately after ...
متن کاملAssessment of Accessory Mental Foramen by Cone-Beam Computed Tomography
Introduction: Any foramen in the buccal surface of mandibular body that transfers mental nerve and vessels except mental foramen, is called Accessory Mental Foramen (AMF). The objective of this study was the determination of the AMF using cone-beam computed tomography (CBCT). Materials and Methods: this descriptive study was done on 180 CBCT projections which were selected by convenience samp...
متن کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
