OBJECTIVE The fetal electrocardiogram system for electronic fetal monitoring (EFM) (STAN S21, Neoventa Medical, Moelndal, Sweden) has led to improved perinatal outcomes in other countries. We aimed to assess the ability of United States (US) obstetricians to use this system appropriately for intrapartum care. STUDY DESIGN A prospective nonrandomized trial(More)
PURPOSE To develop a phantom and measurement protocol for quantifying spatial accuracy of an MR imaging system over its entire imaging volume. METHODS The measurement protocol is comprised of a phantom, a set of MR sequence parameters for imaging the phantom, and analysis software for calculating spatial errors in the acquired phantom images. The phantom(More)
PURPOSE To develop improved distortion correction of MR images based on higher degree spherical harmonic models of the gradient system and the main magnetic field. METHODS The induced field gradient along all three axes can be modeled by first order spherical harmonics. These models provide a true encoding of the physical location of a spin to the(More)

Oxy-coal combustion with recycled flue gas is one of the leading technologies for carbon capture and storage. A mixture of oxygen and recycled flue gas is used to burn the fuel as well as moderate the flame temperature. A flue gas stream consisting mainly of CO2 is produced, which after gas treatment is ready for transportation and storage. However, high(More)
