Imaging receiver
WitrynaRF Receiver. An RF receiver is used to process the signals from the receiver coils. Most modern MRI systems have six or more receivers to process the signals from multiple coils. The signals range from approximately 1MHz to 300MHz, with the frequency range highly dependent on applied-static magnetic field strength. WitrynaImage-Path Receivers. The ultrasound image-path receivers are used to detect 2D as well as pulsed-wave Doppler (PWD) signals necessary for color-flow imaging and spectral PWD. The receivers include a Tx/Rx switch; a low-noise amplifier (LNA); a variable-gain amplifier (VGA); an anti-alias filter (AAF); and an analog-to-digital …

Witryna1 sty 2016 · Many linear Fresnel collector designs use a secondary concentrator above a single receiver tube to reflect those rays to the back of the receiver tube that missed it in the first place. Non-imaging optics [2, 3] allow for an additional concentration via the secondary concentrator by a factor of approximately 2. In other words the target area … WitrynaIn conventional receiver-operating-characteristic (ROC) curve analysis of visual detection performance, the observer is credited with a true-positive response if a visual signal is present somewhere in a radiograph called “positive” by the observer; however, the measured true-positive rate can be different for a given false-positive rate if the …
Witryna1 wrz 2005 · Parallel imaging is a recently developed family of techniques that take advantage of the spatial information inherent in phased-array radiofrequency coils to reduce acquisition times in magnetic resonance imaging. In parallel imaging, the number of sampled k-space lines is reduced, often by a factor of two or greater, …
