Explain how the detection of signals in MRI contributes to image formation.
Model answer
What a good answer should say
- In MRI, signals are detected from the resonance of hydrogen nuclei in the body when exposed to a strong magnetic field and radio-frequency pulses.
- These signals are processed to create detailed images of internal structures, allowing for accurate diagnosis.
Explanation
Why this works
This answer demonstrates an understanding of the relationship between signal detection and image formation in MRI. It tests the student's ability to link theoretical concepts with practical applications in medical imaging.
