The aim of this thesis is to perform robot positioning, based on an odometry which is continuously corrected by different landmark detection systems demanding as less modifications as possible for the environment. Two independent correction systems (a supervised and an unsupervised) were implemented into two different experiences which represent the subject of this thesis. The supervised experi...

The perioperative nurse involved in the intraoperative care of the obese patient is faced with numerous issues and challenges. As a growing number of these patients present for medical care, the nurse must consider the special positioning needs for surgery and the equipment needed to promote the safest environment for the patient. This article addresses positioning considerations for the obese ...

The number of total knee arthroplasty (TKA) procedures continuously increases, with good to excellent results. In the last few years, new surgical techniques have been developed to improve prosthesis positioning. In this context, patient-specific instrumentation is included. The goal of this study was to compare the perioperative parameters and the spatial positioning of prosthetic components i...

Certain regions of the body can be relatively difficult to image optimally by computed tomography (CT). The lower neck falls into this category. A routine transverse image at this level includes the shoulders, which can cause beam hardening [1] . Beam hardening reduces subject contrast and often produces streak artifacts between the shoulders [2, 3]. This image degradation is especially trouble...

In corrective osteotomy of the radius, detailed preoperative planning is essential to optimising functional outcome. However, complex malunions are not completely addressed with conventional preoperative planning. Computer-assisted preoperative planning may optimise the results of corrective osteotomy of the radius. We analysed the pre- and postoperative radiological result of computer-assisted...

introduction: injury to cranial nerves ix, x, and xii is a known complication of laryngoscopy and intubation. here we present a patient with concurrent hypoglossal and recurrent laryngeal nerve paralysis after rhinoplasty. case report: the patient was a 27-year-old woman who was candidate for rhinoplastic surgery. the next morning after the operation, the patient complained of dysphonia and a s...

Introduction: The present study was aimed at evaluating common positioning errors on panoramic radiographs taken in the Radiology Department of Mashhad Dental School. Materials and methods: The study sample included 1,990 digital panoramic radiographs taken in the Radiology Department of Mashhad Dental School by a Planmeca Promax (Planmeca Oy, Helsinki, Finland), during a 2-year period (2010–20...

A technique is described by which the sizes, shape and orientation of the brain with respect to detector positioning can be reproduced by computerized simulation. Head size is estimated from the distance between the external acoustic meatus (EAM) and the outer canthus and head shape is determined from the length and height of the skull. These values are used to magnify and alter the shape of a ...

BACKGROUND AND PURPOSE There is agreement, although little evidence, that consistently positioning stroke patients in allegedly reflex-inhibiting positions is therapeutic and will enhance functional recovery. The nursing staff, therefore, needs to know and implement these postures and understand their potential underlying value. We examined nurses' knowledge of and practice in positioning strok...

Anesthesia followed by placement in the prone position takes time and may result in complications. This study aimed to evaluate the feasibility of awake nasotracheal fiberoptic intubation and self-positioning followed by anesthesia induction in prone-positioned patients under general anesthesia.Sixty-two patients (ASA physical status I-II) scheduled for awake nasotracheal fiberoptic intubation ...
