Signal to Noise Ratio Analysis of Bloch-Siegert B1 Mapping

Introduction: B1 mapping is important in a variety of new MR applications, including the design of RF pulses in parallel transmit systems and flip angle calibration for T1 mapping. The Bloch-Siegert (BS) B1 mapping method has been recently introduced as a fast, accurate and robust technique for B1 mapping [1]. In order to compare the quality of B1 maps acquired with the BS method to other metho...

Signal-to-Noise Ratio Estimation

Of the many measures that characterize the performance of a communication receiver, signal-to-noise ratio (SNR) is perhaps the most fundamental in that many of the other measures directly depend on its knowledge for their evaluation. In the design of receivers for autonomous operation, it is desirable that the estimation of SNR take place with as little known information as possible regarding o...

Signal-to-Signal-to-Noise-Ratio of Full-Field Fourier-Domain Optical Coherence Tomography: Experiment

We report a new approach in optical coherence tomography (OCT) termed full-field Fourier-domain OCT (3F-OCT). A three-dimensional image of a sample is obtained by digital reconstruction of a three-dimensional data cube, acquired using a Fourier holography recording system illuminated with a swept-source. This paper presents theoretical and experimental study of the signal-to-noise ratio of the ...

Cryo-electron tomography of rubella virus.

Rubella virus is the only member of the Rubivirus genus within the Togaviridae family and is the causative agent of the childhood disease known as rubella or German measles. Here, we report the use of cryo-electron tomography to examine the three-dimensional structure of rubella virions and compare their structure to that of Ross River virus, a togavirus belonging the genus Alphavirus. The ecto...

Cryo-electron tomography of vaccinia virus.

The combination of cryo-microscopy and electron tomographic reconstruction has allowed us to determine the structure of one of the more complex viruses, intracellular mature vaccinia virus, at a resolution of 4-6 nm. The tomographic reconstruction allows us to dissect the different structural components of the viral particle, avoiding projection artifacts derived from previous microscopic obser...
