A solenoid used in magnetic resonance imaging (MRI) is wound from a niobium-titanium superconducting wire 2mm in diameter, with adjacent turns seperated by an insulating layer of negligible thickness. ( The solenoid is 2.4 m long and 95 cm in diameter )

Calculate the current in the superconducting wires necessary to produce a magnetic field of flux density 1.5 T at the centreof the solenoid.

The answer is 1.2 k A

Can someone help me please ?

1. Magnetic resonance imaging (MRI) is a powerful diagnostic tool used in medicine. The imagers used in hospitals operate at a frequency of 4.00 x 10^2 MHz (1 MHz = 10^6 Hz). Calculate:
a. the wavelength
b. the energy in joules per photon
c .the energy in kilojoules per mole.

2. Carbon dioxide absorbs energy at a wavelength of 1498 nm.
a. In what spectral range does the absorption occur?
b. Calculate the frequency of this absorption.
c. What is the energy absorbed by one photon?
Please show/explain all work.

I have scoliosis and I had massage today. Therapist pushed my spine too hard and I felt strong pain. This was the place that caused some pain to me before, but now I feel like it was crushed and pain is terrible. I’m afraid that this massage damaged my spine that I was trying to heal for so long. Did anyone heard about similiar cases?
Should I do xray or magnetic resonance to determine the damage, or go directly to hospital?
Please, any information is appreciated.

Im looking for a school that offers magnetic resonance imaging certifications

A patient is having a magnetic resonance imaging scan (an MRI) and has neglected to remove a 6.7 cm diameter metallic bracelet. The resistance of the bracelet is 0.0110 Ω. The magnetic field within the MRI’s solenoid perpendicular to the opening of her bracelet. While taking the scan, the magnetic field decreases from 1.32 T to 0.51 T in 0.900 seconds. What is the magnitude of the average induced current in the bracelet?

Thank you!

Which of the following statements about a system is untrue?
(A) Modern computed tomography (CT) systems use a pencil beam of X-rays to acquire sufficient projections to reconstruct the final image.
(B) Modern fluoroscopic imaging systems use an image intensifier to capture the transmitted X-rays and display radiographic images in real-time..
(C) A Magnetic Resonance Imaging (MRI) system uses the radio-frequency resonance of unpaired protons in strong magnetic fields to produce images.
(D) Reconstruction from projections requires many iterations and the application of complex algorithms to produce an image.

Magnetic resonance imaging needs a magnetic field strength of 1.5 T. The solenoid is 1.8 m long and 75 cm in diameter. It is tightly wound with a single layer of 2.30-mm-diameter superconducting wire. ***What current is needed?
—–im getting 2974 A but this is not right——

I need to know how an MRI works with some simple details.
I also need to know what the magnetic resonance phenomenon is.
Also what does it mean when it says that a nucleus is described to be resonance.
How much would the machine itself cost? 2,000,000?

I am working on methods of segmentation of brain MRI results.I need T1, T2 and Proton Density weighted brain Magnetic Resonance Images. The resolution for these images must be 256×256 or higher.

Thanks
