BACKGROUND Tidal volume (V(T)) must be accurately delivered by anaesthesia ventilators in the volume-controlled ventilation mode in order for lung protective ventilation to be effective. However, the impact of fresh gas flow (FGF) and lung mechanics on delivery of V(T) by the newest anaesthesia ventilators has not been reported. METHODS We measured delivered V(T) (V(TI)) from four anaesthesia...

Abstract Increasing the Main Injector beam power above ∼ 1.2 MW requires replacement of 8 GeV Booster by a higher intensity alternative. In this paper, we consider an linac that produces H - for injection into Recycler Ring or Injector. This upgrade will maximize available neutrino production long baseline DUNE experiment to greater than 2.5 and enable next generation frontier experiments. The ...

Methods ECV measurement was by EQ-CMR. The T1 mapping sequence was ShMOLLI. The contrast agent was Gadoterate meglumine (Dotarem) at 0.1mmol/Kg (bolus) plus infusion at 15 minutes at 0.0011 mmol/kg/min. CMR was at 1.5T (Siemens Avanto). ECV was measured in 43 well-controlled hypertensive patients from a specialist tertiary centre (median age 56, range 21 to 78, 55% male) and 50 healthy voluntee...

Introduction: The presence of heterogeneities such as air-filled cavities in the head and neck treatment fields region, may result in potential dosimetric disagreement because the losses of charged particle equilibrium. Most of treatments planning systems are not able to predict dose distribution of inhomogeneities region accurately. Therefore, dose calculation algorithms need to...

The Gun Test Facility (GTF) was built to test high-brightness sources for the proposed Linac Coherent Light Source (LCLS) at SLAC. The longitudinal emittance exiting the gun has been determined by measuring the energy spectrum after the linac as a function of the linac phase. The phase-space parameters defining the beam pulse width, correlated energy spread, and slice energy spread at the linac...

We present a description and analysis of the data access challenge in the Siemens Energy. We advocate for Ontology Based Data Access (OBDA) as a suitable Semantic Web driven technology to address the challenge. We derive requirements for applying OBDA in Siemens, review existing OBDA systems and discuss their limitations with respect to the Siemens requirements. We then introduce the Optique pl...

INTRODUCTION: The first steps towards Parallel Imaging were made from 1987 on [1]-[5]. Since the introduction of the first clinical examples with SMASH and SENSE by Sodickson [6] and Pruessman [8] it still took several years until the first vendor implementations for Parallel Imaging came up. Siemens introduced the integrated Parallel Acquisition Techniques (iPAT) for the MAGNETOM Sonata, Symph...
