Yes, a magnetic resonance imaging scanner uses an RF pulse to excite nuclei in the body.
Practically all medical MRI scanners are tuned to excite hydrogen nuclei.
Other MRI scanners used in physics and chemistry labs are tuned to excite other nuclei -- see the links for a detailed list.
What else can I help you with?
Name of the thumb pulse?
The neck pulse is the corotid pulse; the wrist pulse is the radial pulse; the arm pulse is the brachial pulse. it seems that the pulses are named according to the artery palpated; therefore, your thumb pulse must be your princeps pollicis pulse. this is an educated guess.
How do you work out RF value?
Rf = distance to color/distance to front line
What does an Rf value indicate?
Rf value indicates the relationship of the distance moved by a pigment to the distance moved by a solvent.The Rf can be calculated by the following equation. Rf=distance pigment migrated/distance solvent front migrated.
What is the minimum value of Rf?
Zero
How do you use excited in a sentence?
I was very excited when I got a puppy for Christmas.
How do you use the word throbbed in a sentence?
He was excited and tired and his pulse throbbed.
What has the author Samuel Devons written?
Samuel Devons has written: 'Excited states of nuclei'
What is staggered PRI?
Background: PRI = Pulse Rate Interval. PRI is a term used in Radio Frequency (RF) systems. Specifically, Pulse mode RF systems, as apposed to continuous wave (CW) systems. Each pulse has an on period, pulse width (PW), and an off period. PRI is the time from the start of one pulse to the start of the next pulse. For example, if a pulse on time is 10 microseconds (uSec) and the off time is 90 uSec then the PRI is 100 uSec. Answer: A staggered PRI does not have a constant on and off time. The off time varies.
A rapid pulse and shortness of breathe in a patient usually indicates the patient is excited and does not need to be reported to the nurse?
False
How does pulse change?
It goes up and down, as you become active or inactive, excited or calmed.
DoesTV affect the pulse-why?
yes because it's certain types of television shows,and movies that you watch and you may get excited and pulse might start at a normal level,and when you get scared then it could get faster,or something.
What is refocusing pulse in mri?
A refocusing pulse in MRI is a radiofrequency pulse applied after the initial excitation pulse, aimed at rephasing the spins of hydrogen nuclei in the magnetic field. This pulse corrects the dephasing caused by magnetic field inhomogeneities and spin interactions, allowing for coherent signal detection. It is commonly used in techniques like spin-echo sequences to enhance image contrast and resolution. By refocusing the spins, it improves the overall quality of the MRI images obtained.
What is the digital pulse modulation?
There are 3 main types of digital pulse modulation:Pulse time modulation (PTM), somewhat similar to analog phase modulation.Pulse width modulation (PWM), the width of the pulse represents the signal.Pulse code modulation (PCM), serial transmission of binary bits forming numeric or character codes that represent the signal.All of these can be modulated on an RF carrier using any of the standard modulation techniques: AM, FM, Phase Modulation, etc. One advantage with AM digital pulse modulation techniques over AM analog is that the carrier can be 100% modulated, which cannot be done with analog, thereby allowing significant reductions in transmitter power without loss of coverage range. Sometimes FM digital pulse modulation techniques are referred to as Frequency Shift Keying (FSK). A very complex method of combining Phase Modulation and AM to increase the bit density of digital pulse modulation on an RF carrier is called Quadrature Amplitude Modulation (QAM).
