why would someone be curious about Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI)? and how is it related to modern physics?

Expert Solution

Nuclear magnetic resonance has lately become a significant tool in medical science where exposure of the patient to a strong uniform magnetic field causes detailed images of his internal structure of organs, tissues, blood vessels etc.

MRI is the machine that creates the field that excites water molecules in the body parts which radiate electromagnetic waves. The effect of these waves on interaction with the tissues gets demonstrated as images.

The protons of water molecule get aligned along the direction of the field and the MRI disrupts it by a producing a weak field . This causes protons to realign gradually. As a result a low energy photon of the frequency of radio waves. Thus, depending on the thickness of tissues, images are produced of tissues where water molecules are present.

Hence, the application and importance of NMR and MRI is a can be well seen as the application of modern physics

You recently requested bids for a new MRI (magnetic resonance imaging) machine in for your radiology department. As a result, two vendors have submitted quotes based off the specs in your proposal. You anticipate the service life of this machine to be 10 years and that it should generate $600,000 per year at 50% capacity. To remove any potential for bias, your compliance department has provided the bids to you (below) and removed the name of each company. Bid: Company...

3) The very first magnetic resonance imaging (MRI) devices employed multi-layer copper solenoids, like the one shown in the figure below. The solenoid dimensions were: length = 2 m and inner radius = 0.4 m. The required magnetic field was 0.3 T. Due to thermal considerations, the copper wire conductor was chosen to have a square cross-section, 10 mm×10 mm, which limited the maximum current in the conductor to 1,000 A. A) What is the minimum number of solenoid layers...

Roxbury's Radiology Center (RRC) performs X-rays, ultrasounds, computer tomography (CT) scans, and magnetic resonance imaging (MRI). RRC has developed a reputation as a top radiology center in the state. RRC has achieved this status because it constantly reexamines its processes and procedures. RRC has been using a single, facility-wide overhead allocation rate. The vice president of finance believes that RRC can make better process improvements if it uses more disaggregated cost information. She says, "We have state-of-the-art medical imaging technology....
