Fast spin echo and gradient echo pulse sequences shorten imaging times. The fast spin echo sagittal image is used to assess for central canal and thecal sac compromise by osteophyte or disk. [ 29 ] ...

Before the first cine acquisition, the gradient-echo pulse sequence was fine-tuned to ensure that the read gradient was balanced, resulting in a more nearly flat background when phase images were ...

Have you ever wondered why a drumbeat makes your foot tap before you even realize it? It’s not magic or mystical prediction; ...

The three-dimensional balanced turbo-field-echo (3D BTFE) sequence is a commonly used fully balanced steady state coherent imaging pulse sequence using a very short repetition time, designed to ...

OBJECTIVES To measure the sensitivity and specificity of five MRI sequences to subarachnoid haemorrhage. METHODS Forty one patients presenting with histories suspicious of subarachnoid haemorrhage ...

Copernicus Sentinel-2 satellite image of the Dickson Fjord in East Greenland. Credit: Thomas Monahan. Credit: Thomas Monahan. It was as if the Earth itself was humming a strange, rhythmic tune—one ...

First, the paper shows a novel sorting method based on delaminating coupling and support vector clustering (SVC). Secondly, it presents a notion of type-entropy. And recognition technology of ...

Some of these warnings could be eliminated by changing the gradient_log.zero and gradient_log.slice parameters. We have also noticed that changing these parameters will yield completely uncorrelated ...

Design criteria are given for low-noise, wideband front-end electronics suitable for pulse-echo operation of capacitive micromachined ultrasonic transducers (CMUTs). To investigate which configuration ...
