Objectives Cone-beam computed tomography (CBCT), despite its advantages, has some drawbacks, such as artifacts and movement of the patient during scanning may lead to motion artifacts (MAs). This retrospective study aimed to evaluate the MAs in three different CBCT devices and to analyze their relationship with age, the …
Ancient Egyptian artwork often depicts people wearing ceremonial head cones, but the role of these head dressings remained a mystery. Journalist and author Annalee Newitz talks about the first piece of physical evidence found of these head cones and what they may have been used for.
The aim of this study was to evaluate the repetition rate of examination due to motion artifacts in horizontal cone beam computed tomography, using three different kinds of head support, with reference to the patient's age. Further purpose was to evaluate ...

Objectives The aim of this study is to investigate the effect of head motion on the reconstruction image quality in relation to patient positioning in dental cone-beam computed tomography (CBCT) systems. This study should be intended as the first step to evaluate the effect of the head movements also in more stringent conditions. Methods …
We give a modern statement and proof of Poinsot's characterization of an arbitrary attitude trajectory in terms of the motion of a cone rolling without slipping on a …

A gradient-based approach to fast and accurate head motion compensation in cone-beam CT ... Cone-beam computed tomography (CBCT) systems, with their portability, present a promising avenue for direct point-of-care medical imaging, particularly in critical scenarios such as acute stroke assessment. However, the integration of CBCT …
Knowing the head positioning reproducibility of frameless systems and their respective ability to limit intrafractional head motion is important in order to safely perform SRS. The purpose of this study was to evaluate and compare the intrafractional head motion of an invasive frame and a series of frameless systems for single fraction SRS and ...
mechanism used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. Fracture occurs in the feed material when the strain developed in it due …
Therefore motion has to be avoided or compensated. Fixation of patients (or organs) is usually difficult. For instance, a recent study showed that even the use of a dedicated custom-made head-rest could not prevent the occurrence of head motion and related artifacts [1]. The method presented in this paper is based on the tracking of …
Computed tomography (CT) reconstruction methods assume imaging of static objects; object movement during projection data acquisition causes tomogram artifacts. The continuously moving heart, therefore, represents a complicated imaging case. The associated problems due to the heart beating can be overcome either by using very …
mechanism used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. Fracture occurs in the feed material when the strain developed in it due to sufficiently applied impact forces, pressure or shearing effect exceeds the elastic limit .Generally crushers are very rugged, massive and heavy in design.
First understanding how motion per se is encoded in the auditory nervous system and second, understanding how the listener is able to disambiguate the actual motion of a source from the apparent motion. Despite almost constant head motion, the fact that we still perceive the world around us as stable may provide some important …
Cone-beam CT (CBCT) is increasingly common in guidance of interventional procedures, but can be subject to artifacts arising from patient motion during fairly long (~5-60 s) scan times. We present a fiducial-free method to mitigate motion artifacts using 3D-2D image registration that simultaneously …
Hyperextension is the abnormal or excessive extension of a joint beyond its normal range of motion, thus resulting in injury.Similarly, hyperflexion is excessive flexion at a joint.Hyperextension injuries are common at hinge …
In a press conference on Friday afternoon at Newman Arena, Jon Jaques '10 was introduced as the new head coach of men's basketball. Jaques, who was a team captain on Cornell's 2009-10 Sweet ...
The cast manganese steel mantle has Jaques Bac epoxy between the shaft and mantle to provide support. The mantle is then secured to the mainshaft by a wear-resistant head nut. A torch ring is also fitted to assist with mantle replacement. Dust sealing mechanism A dust-seal ring serves as a simple but effective way to stop
They reported that Varian exhibits superior image quality (8 lp/cm resolution for head scan and 4 mm low contrast detectability for chest and pelvis scans), but yields higher doses for the head (effective dose 0.12 msV) and pelvis scans (effective dose 4.34 msV) compared to Elekta XVI (effective dose for head scan 0.04 msV and pelvis scan 3.73msV).
Introduction. Cone-beam computed tomography (CBCT) is a well-established three-dimensional (3D) radiographic diagnostic tool for oral and maxillofacial tasks.1,2,3 In addition to its widespread availability, another advantage of CBCT imaging is its lower radiation dose than that of classical computed tomography (CT).4,5,6 As with …
