Practical Applications
## Seeing Inside the Body
Modern physics has led to amazing medical tools that let doctors look inside the body without surgery.
### MRI and CT Scans
MRI uses magnets and radio waves (quantum physics!), while CT scans use X-rays to create detailed images.
### Fluid Dynamics in Medicine
Understanding how blood flows helps diagnose heart problems and design better treatments.
### Improving Health
These technologies have saved countless lives and improved healthcare worldwide.
Examples
- Doctors use ultrasound to check on a developing baby’s health.
- MRI scans help spot brain injuries quickly and safely.
