30s - Q3
Transitions between quantized energy levels can occur only when energy is supplied or absorbed at a specific frequency in the range of radiowaves, called the:
Larmor resonant frequency
Faraday's law of induction
RF
SNR
30s - Q4
The unit of field strength outside of the magnet is:
Gauss
Tesla
30s - Q5
True or False: Bo has its intensity expressed in terms of tesla (T).
truefalseTrue or False30s - Q6
True or False: Receiving radiofrequency coils can only measure the MRI signal along the X and Y axes; i.e. no measurement can be made along the axis of the main magnetic field.
truefalseTrue or False30s - Q7
Which of the following statements best describes the reception of the MR signal from the patient?
Precessing nuclei, within the patient, send a radiowave to the wire loop antenna
vibration
30s - Q8
Faraday’s Law of Induction states that if a loop of wire is moved through a magnetic field, it will create in the wire
A voltage
A signal
30s - Q9
In a typical whole-body superconducting magnet, the direction of the magnetic field is:

The direction of the magnetic field in a typical permanent magnet is:
Vertical
Horizontal
30s - Q11
Family members and ancillary personnel accompanying the patient into the scan room:
Do not have to be screen since they are not actually going into the isocenter of the bore
Should be screened as if they are going through the procedure themselves
30s - Q12
The people who should be educated about the effects of the static magnetic field, especially in high field superconducting magnets, include
Users sort answers between categoriesSorting30s - Q13
A mathematical operation performed on the FID to produce an image is called:

Shim Coils
RF Coils
30s - Q15
