SSFP Diffusion prepared SSFSE
Introduction The bright signal of fluid and blood can affect tumor detection in screening applications. Diffusion weighted EPI is now frequently employed to attenuate these signals and highlight tumors. Gradient pulses can also be added to unbalanced SSFP sequences to attenuate the signals with motion. It has been demonstrated that SSFP sequence is strongly sensitive to self-diffusion or other ...
متن کاملCalculation of the Scattered Radiation Profile in 64 Slice CT Scanners Using Experimental Measurement
Introduction: One of the most important parameters in x-ray CT imaging is the noise induced by detected scattered radiation. The detected scattered radiation is completely dependent on the scanner geometry as well as size, shape and material of the scanned object. The magnitude and spatial distribution of the scattered radiation in x-ray CT should be quantified for development of robust scatter...

15 صفحه اولEvaluation of techniques for slice sensitivity profile measurement and analysis
The purpose of this study was to compare the resulting full width at half maximum of slice sensitivity profiles (SSP) generated by several commercially available point response phantoms, and determine an appropriate imaging technique and analysis method. Four CT phantoms containing point response objects designed to produce a delta impulse signal used in this study: a Fluke CT-SSP phantom, a Ga...
متن کاملCorrection of B0 induced slice profile distortion using parallel transmit
Introduction: With the advent of parallel transmit (PTx), there has been much interest in creating complex spatially localised excitations. The algorithms which calculate the requisite pulses [1,2] require an estimate of the B1 field produced by each coil, and also a map of the B0 (off resonance) field, since this distorts the excited magnetisation profiles. In fact spatially localized excitati...
