Patient positioning is an integral part of perioperative care and yet it is an area of patient care which can easily be compromised as staff try to accommodate surgeons and work through busy operating lists. Inadequate padding and incorrect positioning can cause serious and long term injury and disability, and can result in litigation against perioperative nurses and ODPs.

in present pet/ct scanners, pet attenuation correction is performed by relying on the information given by ct scan. in the ct-based attenuation correction methods, dual-energy technique (dect) is the most accurate approach, which has been limited due to the increasing patient dose. in this feasibility study, we have introduced a new method that can implement dual-energy technique with only a si...

In this paper, the problem of achieving high accuracy positioning of a medical robot is studied. The Northeast Proton Therapy Center, at the Massachusetts General Hospital, is a new cancer research and treatment facility. A major component of the center is a robotic patient positioning system that will carry and position patients in a proton beam. The desired positioning accuracy of the robot i...

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...

Study design: Prospective Observational study. Objectives: To study whether the acetabular cup size and vertical offset in primary total hip arthroplasty are correlated or both independent of each other. If correlated, directly related to other inversely. Methods: A prospective was conducted Department Orthopaedics, PGIMSR, New Delhi. 25 cases ages 20 70 years were identified who had undergone ...

this article is intended to provide an overview of various aspects of clinical pet/ct. these include discussions of: (i) important areas of clinical application; (ii) opportunities in clinical research; (iii) scanner and operating-mode considerations (e.g. bgo vs. lso, lyso or gso scanners, 2d vs. 3d imaging). (iv) study-specific considerations (e.g. patient preparation and positioning issues, ...

To investigate Cherenkov imaging (Cherenkoscopy) based patient positioning and movement tracking during external beam radiation therapy (EBRT). In a phase 1 clinical trial, including 12 patients undergoing post-lumpectomy whole breast irradiation, Cherenkov emission was imaged with a time-gated ICCD camera synchronized to the LINAC pulse output, during different fractions of the treatment. Pati...

1  Abstract—The radio interferometric positioning system (RIPS) is an accurate node localization method featuring a novel phase-based ranging process. Multipath is the limiting error source for RIPS in ground-deployed scenarios or indoor applications. There are four distinct channels involved in the ranging process for RIPS. Multipath reflections affect both the phase and amplitude of the rang...

Over the last years precise point positioning (PPP) has been receiving more attention as it provides a cheaper way to achieve decimetre and centimetre precision levels when compared to the typical differential techniques. While differential techniques rely on two or more receivers to differentiate their observations and cancel out most errors, PPP only uses undifferenced observations from a sin...
