What is it?
Medical imaging is the use of physical techniques to produce images or information about structures and processes inside the human body for medical examination and diagnosis.
In simple words
- Medical imaging uses physical signals to obtain information about internal body structures.
Recommended for Class 12
Full school-level explanation
Medical imaging is the use of physical techniques to produce images or information about structures and processes inside the human body for medical examination and diagnosis.
X-ray Imaging
Medical imaging allows doctors to examine internal body structures without directly viewing them through surgery. Different imaging techniques use different physical principles. Uses X-rays, which are electromagnetic waves with high photon energies. Different tissues absorb X-rays by different amounts.
Ultrasound
Uses high-frequency sound waves. Reflections from boundaries between tissues are detected and processed to form an image.
CT Scanning
Uses many X-ray measurements taken from different directions. A computer processes these measurements to create cross-sectional images. Medical imaging is an important application of waves, electromagnetic radiation, electronics and computer processing.
Formula / Key Relation
A general imaging idea is: Physical signal → interaction with tissue → detector → processing → image
Remember
- waves, electromagnetic radiation, electronics and computer processing
- Physical signal → interaction with tissue → detector → processing → image
