this workshop features, (live) demonstration of sonographic technique of the upper extremity joints; patient positioning; transducer choices, operation and position on the anatomic landmarks; optimal evaluation of the anatomic structures in shoulder, elbow and wrist; hopefully on thursday or friday.

Introduction: Integration of single photon emission computed tomography (SPECT) and computed tomography (CT) scanners into SPECT/CT hybrid systems permit detection of coronary artery disease in myocardial perfusion imaging (MPI). Misregistration between CT and emission data can produce some errors in uptake value of SPECT images. The aim of this study was evaluate the influence...

When setting up patients via image-guided positioning for external-beam radiotherapy, one can often determine the rotational corrections needed for optimal alignment, but once measured, they are not always applied. However, in rigid-body setup calculations the optimal translational component of the setup correction will be different depending on whether rotations are included or excluded from t...

The code-phase divergences, which are minimal for GPS, GLONASS, and Galileo satellites, are commonly found in BeiDou Navigation Satellite System (BDS) Geostationary Orbit (GEO), Inclined GeoSynchronous Orbit (IGSO) and Medium Earth Orbit (MEO) satellites. Several precise positioning applications which use code observations are severely affected by these code biases. We present an analysis of co...

Pectus excavatum deformity often remains clinically asymptomatic even in cases of a severely diminished thoracic volume and frequently remains uncorrected. In the patient population that requires left ventricular assist device (LVAD) placement, a diminished thoracic volume can be problematic and lead to significant challenges in pump and outflow cannula positioning. Here we present a case of pe...

Patients undergoing surgical correction of scoliosis present many challenges to anesthetists because of the pathophysiologic derangements caused by the disease and the demanding nature of the anesthetic care that is required. A thorough understanding of the pathophysiology of the disease, intraoperative concerns specific to the procedure, and the efficacy of various anesthetic management techni...

The reproducibility of lateral radiography of the knee joint in the lateral position is low because patient positioning can be easily affected by passive rotation of the knee joint. We calculated the correction angle of the femoral external rotation and the lower leg elevation and developed our own auxiliary tool for obtaining a lateral view image. We were able to obtain, in a single attempt, a...

We introduce a wearable pedestrian indoor localization system with dynamic position correction. The system uniquely combines dead reckoning and fiducial marker-based localization schemes, exclusively using widely available, low end and low power consumer hardware components. The proposed system was tested with various walking patterns inside a building, achieving an indoor positioning accuracy ...

Integrated PET/MR is a newly available imaging technique that includes a simultaneous whole body MR and PET examination Integrated PET/MR avoids co-registration errors in image reconstruction due to differences in patient positioning and has potential for MRI based motion correction to improve registration in the upper abdomen PET/MR is most likely to be advantageous for cancers that are now im...

In fluoroscopy guided interventional procedures, a ceiling suspended screen is used to protect personnel for scattered X-ray radiation arising from patient treatment. The correct positioning of the crucial proper occupational protection. proposed solution in this paper provides reliable and efficient protection radiation, based on an device protective merging into one system via appropriate int...
